How good is this card in a regular build that doesn't include something like Lockpicks?
Let's do some math:
On Standard in The Innsmouth Conspiracy, there are 20 tokens in the bag to start. Let's assume that only +1, 0, and will trigger this (since you're trying to be at +2 for all checks). By my calculation, you have a:
- 36% chance if you make two tests per turn
- 48% chance if you make three tests per turn
- 59% chance if you make four tests per turn
I think assuming two tests is fair since you'll be using actions to Play and Move. You might also get tests during the Mythos Phase but you probably won't be at +2 for those checks. If we assume that the scenario is 15 turns long, you'll net 5.4 cards if you play it on turn 1 but only about 2.7 if you play it mid-game. That's not great. Preposterous Sketches will get you three cards immediately for the same cost and not take up your Accessory slot. Obviously, this card starts to look better if you can take more actions per turn (thanks to something like Leo De Luca) or if you routinely test at above +2.
