As always, don't forget to press the ♥ if you like the Deck and want to give visibility to my work :)


Introduction

Finishing this series of 6 investigator decks (all but Gloria), to help people who have little time to deckbuild, or are still getting familiar with the new cards. May these serve as a base for you to build your own decks and adapt to any other campaign or group size.

Disclaimer These decks have been play-tested in 2 teams, yet not through The Drowned City Campaign since they are published before its official release. Enjoy the reading, and I hope you'll have fun with these!


Sorry for the longer waiting time for this deck, but there was a bug on ArkhamDB that had to be fixed first. Thanks Felice for the pull request, making it possible for everyone to create Agatha Crane decks! Be sure to check his incredible work on Arkham.build for a greatly improved deckbuilding experience.

Overall Agatha wasn't the highest on my hype list, but after playing her, I think she is one of my favourite investigators of the new set, and her ability involves a lot of decision making and rewards greatly careful planning and decision making.

Main Strategy

Find the Text Between the Lines

Agatha Crane's ability is extremely powerful but is tricky to trigger reliably, especially on her side. In this deck, we are using two different ways of triggering your ability:

  • Ocula Obscura to reveal the hidden text. It is the best option since it triggers your ability by playing the game, with even the benefit of having Premonition every phase.

    • A little word about the Ocula Obscura since it really is the star of the show here. Once it hits the table, you will be almost guaranteed to trigger your ability each turn. The only issue is when you pull symbol tokens, but since your ability counts the whole round, token pulls during the Mythos phase also count.

    • If you have been unlucky with tokens and this is your last test this turn, you can use the Eyes of the Dreamer to pull more than one and increase your chances of finding a non-symbol token significantly. This will not only secure your ability but also give you a known token pull on your next test.

    • Note that the Forced ability of the Ocula Obscura is happening before the ability. So during a test, it is possible to release and seal the same token, effectively keeping it locked with you, as long as you don't test more than once per phase!

  • Eyes of the Dreamer is your imperfect alternative. Using the charges one by one should be enough to cover for at least half a scenario, which provides time to find your Ocula Obscura, or the other copy.

    • Because it uses , you will have to spend resources into Higher Education for every test, though revealing more than one token at a time helps. For instance, if there is a -3 and a -5 in the chaos bag, testing at 3 above will cover any pull but the -5 and .

    • The Eyes force you to spend one action for one clue which is slow and can feel quite frustrating when your hand is full of clue compression. But activating your ability is so important that it will be worth it as long as you have a good target in your discard pile.

  • Correlate All Its Contents is the last option. It is decent, especially since it then comes back with your for another clue. However, it can lead to some feel-bad moments if you cancel the first token revealed and turn a pass into a fail.


Make That Degree Worth it

Since most of our events use and Eyes of the Dreamer uses to investigate, we need a reliable way to boost both stats.

  • In the version, we have access to the recently untabooed Higher Education which conveniently covers both stats, and is permanent.

  • To use Higher Education, we need:

    • 5 cards in hand. There is a critical mass that you want to achieve with draw. If you don't have enough cards in hand to use Higher Education, you'll be tempted to commit cards to compensate, making it increasingly hard to reach the hand size requirement. So if you go lower than 5 cards, don't be scared to power draw for a little bit, especially since you are likely to find one of your many draw events: Boosted Blood-Rite and Preposterous Sketches (2) which can both be doubled with your

    • Once you can activate it, you need a steady flow of resources to pay for each test. This is achieved with Dr. Milan Christopher, and events like Burning the Midnight Oil, Cryptic Writings and Voice of Ra which can all be recurred with your ability.

Supercharged by your ability, both card count, and resources shouldn't be a problem past turn 2 or 3, and therefore, passing tests either.


Access the Hidden Tempo

Now that we know how to pass tests and activate our ability reliably, all we need are high-tempo Spell and Insight events to use and abuse. While playing Agatha, your discard pile will basically act like a second hand, full of great events, that you can pick based on your immediate needs.

Here's a little breakdown of all the replayable events in this deck:

Knowing that all these cards are usually used the first time to land in your discard pile, re-using them with your ability offers incredible compression, and turns when you discover 4 to 6 clues will feel like the new norm.

This is a good moment to discuss one of the things that I love the most about this game: how an investigator's ability can completely change the way we assess a card's value. Crack the Case is almost always better than Cryptic Writings (except in degenerate infinite decks), but because of the strict timing window on Crack the Case, it doesn't work with Agatha's ability, making it a worse option in her deck.


A Little Theorycrafty Note

It seems possible to pilot this deck as follows:

  1. Commit all your resource and draw cards during tests
  2. Only use play actions on clue compression events
  3. Only use your ability on card draw and resource first
  4. As you will cycle through your deck a first time, you will have a deck newly formed with only clue compression stuff, that you can then play and recycle

While this seems possible on paper, I never quite made it there when playing the deck, and I think it's only achievable with a certain starting hand, which probably includes:

  1. Occult Lexicon to add more draw power in your deck
  2. Ocula Obscura, or at the very least Eyes of the Dreamer

However, this strategy comes with a risk. Committing your draw and resource events instead of playing them twice may result in you struggling to reach a hand size at 5 or above for Higher Education, or having enough resources to pay for your events twice, while also having to pay to boost your skill value and pass tests. And once they are removed from the game, if you run out of steam, you'll fall flat.

Instead, the way I have piloted this deck is closer to playing more draw and resources early to build momentum, and then the clue compression later when I have my Higher Education secured and my assets in play.
I would only discard some events with Scroll of Secrets (3) when I was already swimming in resources or had more clue compression than I needed, to thin my deck.
I then used my ability on either maintaining Higher Education and my resources, or on more clues.


Other Cards
  • Scroll of Secrets (3) is amazing in this deck for multiple reasons:

    • To draw 3 cards in one play action
    • To try to find and remove Glimpse the Void or your Random Basic Weaknesses
    • To locate Ocula Obscura
    • To thin your deck by discarding a few events so you can access them with your without needing to play them in the first place. The first copy of Fortuitous Discovery is a great target of course, but Preposterous Sketches or Voice of Ra can also be good targets once you are setup.
  • Dr. Milan Christopher shining brighter than ever, providing a very appreciated static and drip economy for Higher Education

  • Hiking Boots, covering the main action drain which is movement. They feel good because they often give you a move the same turn you play them, softening the action cost. They then move you to another location to investigate as soon as you're done with your current one.

    • The static is excellent since it brings your basic value to 4, which is enough to throw a few evades if need be.
  • Spectral Shield to use your extra Eyes of the Dreamer for survivability.

  • Deduction for a little more compression.

  • Eureka! for more consistency, and they commit to both and tests

  • Promise of Power to have any player in your team pass any scenario test


Early Campaign

The deck is really similar, except for:


Late Campaign

As we get more experience, the deck remains almost exactly the same, and we are only going to add more consistency.

  • Studious increases our starting hand. This offers both a better mulligan and an easier start for Higher Education

  • Ancestral Knowledge gives us a card draw per turn for the first 5 turns of the scenario, and most of the cards are cantrips, therefore thinning the rest of the deck.

  • Cryptic Research is still a fantastic (broken?) card, except that the fast effect doesn't matter for your ability, so it is a little expensive compared to Preposterous Sketches (2). Being able to use it on allies or being fast in the first place still feels incredible and it is a solid late buy.

  • Perception (2) and Deduction (2) are great upgrades since they attach to Ancestral Knowledge for a high tempo even early in the scenario.


Group Size


Notable Exclusions

  • Sadly, after really trying to make it work, Uncanny Specimen didn't make the cut. It's not that it's a bad card. It synergises well with Ocula Obscura by cancelling symbol tokens to hopefully turn them into something that the Ocula can seal. But in practice, I often chose not to cancel symbol tokens because they usually meant passing the test, and I was too afraid to turn a pass into a fail.

  • At a Crossroads isn't here because it felt better to be able to kick my draw at the moment I chose, rather than anytime. Timing is crucial to Agatha since you often try to plan what you are going to do with your ability and losing an action next turn may make it much harder to optimise. On top of that, it doesn't work with her , so it's a good opportunity to let go of the card for once!

  • Backpack (2) was in my deck until late testing. I decided to remove it because if you already find your Ocula Obscura, or at the very least Eyes of the Dreamer, it can turn into a dead draw. So I'd rather invest in pure draw, which will give me value no matter the state of the game, including by increasing my hand size for keeping Higher Education online. Finally, I am also keen on reducing its use because Return to The Forgotten Age is now increasingly harder to find, and I suppose a lot of players will not own this card going forward.

  • Deep Knowledge looks like Preposterous Sketches (2) but at 0xp, right? As Agatha struggles a bit with her skill value, adding to the chaos bag can be more detrimental than usual. Plus using them with your leads you rapidly to 8 in the bag, which is not negligible anymore. If you like consistency like I do, then you'd rather avoid it!

  • Another one is Thorough Inquiry, and the reason is again that it is complicated with your , so I'd rather focus on cards that combo with your special ability!

  • Farsight, because it's 4xp for the equivalent of one extra action each turn. For comparison, Hiking Boots gives me roughly the same output, for 1xp.

Final Thoughts

The Agatha was an interesting challenge. She didn't come with many ways to reliably trigger ability, but this is a good balance to how powerful the events are that she can recur. Compared to Agatha, this deck is less versatile and more focused on emptying locations before others have the chance to come in. I am really happy to have both decks shining in different use cases, rather than one strictly better than the other.

It has been a pleasure to build and play with Agatha overall since she really changes the way we assess events. It feels nice to replace staples that do not work with her with less used cards from the card pool.

Finally, this deck's power will vary a lot between average players like me and experts who will play her often and learn how to pilot her based on each starting hand and the momentum of the deck. I gave her an A+ rating as she is a strong A Tier in my hands, but I have no doubt that some better players will make this deck an S Tier contender.

Nice deck. If the deck guide and the review didn't give it away, i'm quite fond of Sagatha myself. What you've put together look simple, yet effective !

Not that I'm complaining, but I'm not sure what led you to list my deck as an inspiration to yours, since the only important component they really share is Higher Education...

Does Ancestral Knowledge work like that ? My read has always been that you need 10 skills in your deck before purchasing it, as opposed to adding it and filling the extra slots with the required skills.

May 12, 2025 RyanMuQ · 1695

Possibly the most time taken from deck building to actual releasing :)

Nice to see a proven Seeker Agatha deck. It would give me some confidence to refine my own deck (for my first run, I realized how painful is to wait for the key component in the 35-size deck).

I noticed that how thirsty this deck is for resources: 2xDr. Milan Christopher, 2xBurning the Midnight Oil, 2xCryptic Research, 2xVoice of Ra. Is it because of Higher Education?

May 12, 2025 Valentin1331 · 89591

Hey @aurchen Sorry I didn't realise it put your deck as Derived from but it makes sense, since I duplicated your deck to create this one, because I didn't know how to make my own because of the bug ^^'
I read your review for Agatha Crane, and good job summarising all the information, it's a lot. I have to say I am also very found of her too, the more I played with her the more I enjoyed it!

And regarding Ancestral Knowledge, I double checked and basically the way it works is that you check the deckbuilding requirements at the beginning of a scenario, and in between, you can meddle with your deck the way you want to (within the boundaries of your available experience). So as long as your deck is valid at the start of your next scenario, you're good to go!

Hey @Valentin1331, thanks a lot for sharing this deck! I really appreciate the work you put into it — the card choices and synergy look great.

I did notice something that I'm a bit confused about, though. I saw there are 3 copies of Fortuitous Discovery in the list, but I thought the deckbuilding rules limit it to 2 copies per card. Is there something I'm missing, or ...?

Thanks again! Looking forward to your thoughts.

May 15, 2025 Kwaice · 7

@haspergm yeah it has the myriad keyword which allows 3 copies of a card

May 18, 2025 Daerthalus · 16

I dont think the trick where you keep sealing the same token works. The first part triggers from revealed tokens, but the forced effect replaces the token reveal and instead resolves the sealed token. The sealed token is never actually revealed.

May 19, 2025 RichardPlunkett · 12

It's not entirely clear, but I suspect I am with Daerthalus on this. There seems to be a resolved vs revealed issue here, and I am not convinved the forced effect "reveals" the token it "resolves".

Forced - When you would reveal a token from the chaos bag: Resolve the token sealed here instead, then release that token.

After you succeed at a skill test, if no tokens are sealed here: Seal a non-symbol token revealed during this skill test on Ocula Obscura. (Limit once per phase.)

May 19, 2025 Valentin1331 · 89591

Thanks @Daerthalus and @RichardPlunkett. Being not the best with rules myself, and finding it also a big weird, I went to ask where the gurus dwell (#rules-discussion on the Mythos Busers' Discord) when writing this Deck Guide.

The consensus over there was:
It is unclear if it is what they intended, but RAW say it is possible. However, a question was sent to the Devs to clarify this interaction, and as of today, it hasn't been answered.

As soon as we know more, I will come back to the guide to update it if needed :)

With all this being said, as always, if it feels wrong for you, the beauty of a cooperative game is that we can use the rules the way we want to, so feel free to house rule it the other way around until we have a definitive answer!

May 26, 2025 gnarb · 4

This is amazing! I tried it in a standalone and had so much fun.

What do you think of Archibald MacVeigh? :)

There was an interesting deck by SaltyElderberry that tries to get infinite secrets from Tomes to pay for events, but is that too much set up for similar results to this deck? Would more expensive Insight events be worth it?

May 27, 2025 Valentin1331 · 89591

Yeaaah @gnarb I'm glad it worked for you! I had a blast playing Agatha but somehow it seems like the community is not picking up on her...

I really liked the idea behind the Archibald MacVeigh deck for sure, but I think it takes too much space (and experience) to be slapped onto any Agatha deck. Especially because eventually, it's still only about resources, and how many more resources can you expect from the straight output of Dr. Milan Christopher?

So all in all, I'm really happy that there are coexisting builds for Agatha Crane, but I don't think they are mergeable.

Jun 14, 2025 dmance · 1

how can i import that 0xp deck into artkham db?

Jun 15, 2025 RichardPlunkett · 12

It's possible to link your arkham.build account to your arkhamdb account and synchronise decks. Alternatively, try exporting there as text and importing here as text. Should mostly work with perhaps only few things to manually fix, depending on the deck.

Sep 11, 2025 Portinou · 1956

@Valentin1331 Official FAQ states: "If an investigator is instructed to “resolve” multiple revealed chaos tokens, any game or card e ects which refer to “the revealed chaos token” in the singular should be construed to apply to each of the revealed chaos tokens. For example, when applying chaos symbol e ects during Step 4 of a skill test or applying modi ers to an investigator’s skill value during Step 5 of a skill test, the e ects and modi ers of all of the resolved chaos tokens should be applied, even though the rules state “the revealed chaos token.” Similarly, any card e ects that refer to “the revealed chaos token” refer to all of the resolved tokens"

So sealing the just yet resolved token is legit. What is intended? Probably not. But this is literally the rule.

Sep 11, 2025 RichardPlunkett · 12

That last line: "Similarly, any card effects that refer to “the revealed chaos token” refer to all of the resolved tokens" seems pretty darn convincing. Great work @Portinou.

Now all we have to do is hope that nobody gets an answer from the current devs, else they will likely screw it up :)

Dec 11, 2025 Masnonet · 4

According to the ArkhamDB Rules: "A sealed chaos token is not considered to be in the chaos bag, and therefore cannot be revealed from the chaos bag as part of a skill test or ability."

No endless loop on Ocula Obscura I fear
