Some observations:

Since the committed card gains after it's committed, this doesn't let you commit cards that don't a matching symbol or cards (like Emergency Cache) that don't have any skill symbols.

The effect only applied to skill cards, not any card you are using to support a skill check.

Minh Thi Phan, the Secretary. Assistant.

The best* seeker in the game, and the worst^ seeker in the game. Minh revolves completely around her access to her signature Analytical Mind, without it she struggles to pass tests without depleting resources and is forced to huddle around her allies to make use of her ability. Once Analytical Mind is in play, however, her potential is unshackled and she can project unparalleled support across the map while accomplishing her own clue-oriented objectives.

For this reason Minh is below power curve until she has two No Stone Unturned (5)s to guarantee immediate access to her unique asset. Past 10xp Minh begins to outpace her contemporaries, and past the midpoint of a campaign she should be trivializing (through some combination of hard card draw and Deciphered Reality) scenarios which severely hamper others.

Obviously she’s better in higher player counts, but she is more than effective enough in 2p. A late-campaign Minh can reach tiers of effectiveness even a pre-taboo Rex would flinch at.

* above 20xp

^ below 10xp

It’s worth reconsidering Minh a few years after her debut. And it’s because nearly every beneficial card survivors have for clues is in the 0 to 2 XP range.

In terms of assets, the mariner's compass lets you run a speedy-efficient dark horse Minh. In duo, you can clear most locations in one action. With scavenging, you can recur the ice pick(3) and make it three clues. Or use scavenging(2) to continually grab your old keyring.

The new survivor skills are also amazing. In your hands, unexpected courage (2) is a ???. With analytical mind, you can use it all game to mitigate tests they won’t pass but are punished by how much they fail. You even get a card! Plus, you can recur it to help deal with your weakness.

Signum Cruces can fill the bag with blesses, even if you’re intending to use a fire axe and succeed. Unrelenting lets you take test without symbols that penalize you for trying.

On the seeker side and ignoring recursion, Ancestral knowledge and Guided by the Unseen get you more skills. And while Ancestral might make PMP harder to trigger, it allows you to get skills you need later, like stunning blow. Congratulations, the guardian just evaded the boss! No more retaliate this turn!

There’s a lot that makes you hardier than a normal seeker: bandages, jury-rig, hiding space… So many different ways to build the seek-tary. (Although most of them involve the card you can get from either color, grisly totem.) Plus, you can use it to help deal with your weakness.

Now go get a lot of clues and make your team more efficient!

All the reviews I read on Minh do her little justice. You can look at her ability and frown a bit, but it is not what makes her strong. Her stat line is not perfect, but it is perfectly reasonable - at 4 Will and easy access to +2 from comitting a single symbol she is very resilient to the nastier effects of the mythos deck. Her 2 foot is not stellar, but if she commit a symbol and someone else commits a symbol she is at 6 Agility. Plus her 7/7 health pool is a blessing, since Seeker allies tend to soak horror better.

She is ridiculously strong and among the best Seekers in the game after only 4xp. The reason? Scavenging 2 + Seeker 5. Its an unique combination that gives you the best of red plus the best of yellow. Scavenging in a Survivor deck is all nice, but most Survivors have trouble to pull it off easily out of the box and even when they can survivor has very few items worth scavenging. Darrel can, but he doesn't have access to good cards to scavenge aside from Old Keyring. Minh and Rex are unique in this regard, but Minh does it more consistently from Turn 1 and can play scavenged items without spending an action with Scavenging. Considering that Rex get a clue for free, but has to spend turns playing scavenged items almost evens the clue game all by itself.

Two cards make the core: Scavenging and Schoffner's Catalogue

Shoffner can pay for all of your AND your allies items. And it takes no slot. It's basically a 3 resource card (2 cost, 5 return) that auto-recurs. It is easy to over succeed after you play your seeker items. Even on tough shroud you only need to commit 1 symbol to reliably overshoot the check (on Standard difficulty. On higher difficulties Encyclopedia or Dream Diary should be considered.

Scavenging + ANY item with ? (Rabbit's Foot or Encyclopedia or Hyperphysical Shotcasterfor commit turns her ability into a mini-Darrel. You never actually play these items. You just commit them over and over again.

Scavenging + The Necronomicon. Minh is THE BEST Necronomicon user by none. Overstack on Hand slots, play cheap assets like Magnifying Glass to go over your hand slot and discard necronomicon. Recur, play for free with Schoffner. Trivialize every monster.

Scavenging + Scroll of Secrets. Scroll of Secrets is Gloria Goldberg in the form of 3xp 1cost seeker item, which you recur and play for free with Schoffner's Catalogue

Expensive Seeker assets like Fingerprint Kit and Fingerprint Kit or Grim Memoir are a joke to pay for Minh. With Research Librarian you can tutor either your Schoffner's Catalogue to load on resourced or The Necronomicon start the chain reaction depending on what you get in your starting hand. Put a single copy of Astounding Revelation makes Research Librarian pay for itself.

Tried her again with the TSK card pool. She's still bad.

The problem is her weakness.

Let's compare Minh to the first seeker in the game everyone has access to: Daisy.

Stats (Winner: Daisy) Daisy has a 5 int, whereas Minh has 4. Daisy has a lower Will, but a higher sanity and can safely fail will checks easier.

Survivability (Winner: Tie) Minh is more durable with 7 health, whereas Daisy is quite squishy with only 5. Minh has access to survivor cards like leather coat and Jessica Hyde, but Daisy has deny existence. Overall, they can both stay on the board pretty well.

Card pool (Winner: Tie) Some really good survivor cards came into play with TSK. However, they both aren't really going to want to delve too deep into their offclass as the seeker cards themselves are still pretty nuts.

Weakness and Sig Asset: (Winner: Daisy, by light years)

Daisy and Minh both get assets that completely lock up a hand slot,and limit each character to one hand. Daisy's signature asset completely locks down her weakness though, and basically ends up netting her one hand at the cost of increasing the auto fails in the bag by 1. Minh's weakness on the other hand completely locks down Minh's signature asset to where she basically can't use it if King in Yellow is on the field. For Minh to clear the King, she's going to want to be draw heavy so she can over commit. Since she's draw heavy though, she's going to be drawing the King a lot too. If youre playing with more than one actove hand slot, you always have the threat of King bumping one of your slots. Compare that to a draw heavy Daisy. Once she has necronomicon safely tucked in her book bag, it's a non issue for the remainder of the game.

Investigator ability (Winner: Daisy, by light years).

Minh can boost each investigator by one each time. They're probably not attempting checks they couldn't innately pass anyway, and this ends up essentially being pretty useless. Daisy on the other hand gets a free action on tome abilities, which she will most likely use on Old Book Of Lore. Draw (and even free asset play) each turn, pretty much every turn, guaranteed.

Overall: Daisy.

The librarian will outperform the secretary in almost every scenario. Since they're both competing for the same role... I find it hard to ever really recommend Minh. I have yet to find a deck build for her that Daisy can't do better, and as such she's a C Tier investigator for me.
