I'm thinking Tony Morgan should strongly consider this card as an early upgrade. First off, he's already motivated to fight enemies with Bounties on them with an upgraded .41 Derringer. With his native 5 you can already see that, just by doing what Tony already wants to do, you can easily achieve 5+ action turns. Then you factor in all the ways you'd normally try to get big action turns with Rogues: Leo De Luca, Ace in the Hole, Borrowed Time, an easily activated Quick Thinking on, say, a Derringer Fight test, and maybe couple that with Double or Nothing if you're feeling extra cheeky.
Also I think this was overlooked in the other review, but I think it's interesting that Borrowed Time lets you defer actions by spending actions. This means technically if you have 3 charges on Borrowed Time, you can continually defer those actions all game and you'd technically be taking 6 action turns. This means that, if you choose to defer those actions over and over again, you can play Pay Day for 6 resources whenever it comes up. Not bad.
Now it's unrealistic to say you'd be able to achieve the maximum number of potential actions in one turn because it's so heavily dependent on oversuccess and having the right cards all at once, but just for fun let's see what's possible. Start with your default 3. You gain +1 from doing at least one Bounty Fight and +1 from Leo. Use Quick Thinking and Double or Nothing on a Derringer test (without Taboo you could commit 2 Quick Thinking) to net +4 actions (or +6 without Taboo). Gain +3 from Borrowed Time and another +3 from Ace in the Hole. You're looking at 15 or 17 actions depending on Taboo. Will you ever get that many? Probably not, but you can easily get 5 or so between Tony's ability and Leo, and 6 or 7 won't be hard to pull off thanks to Quick Thinking and Derringer. If you have the Borrowed Time loop happening, you can bump all those numbers up by 3 easily.
