[quote=@rush99999]The wording says the move makes use of "an earlier failure". It says nothing about whose failure that is.

It says you "reveal how an earlier failure is part of your larger plan", which implies the trickster would have known about the failure beforehand to have it as part of their plan/long game. The three options listed say you do something, such as seize a resource or create an opportunity, and right after it says "on a miss, you’re the one who is blindsided by your own cleverness; your feint plays right into the hands of your opposition to disastrous and immediate effect." It calls the failure a feint; as in, you pretended to fail, and it does specifically call it "your" feint.

We might just be reading it with different lenses. Either way, I'm not trying to argue that it shouldn't work here, and it seems like Fellsing got an idea of how to implement it already too, so that's great! And I also don't mind if it's broadened to work on everyone's failures regardless of whether they were pre-planned or not, that could lead to more fun stuff. Just saying I don't think that was the original intent of it and it might be difficult to come up with stuff for it at times. 

But also, who knows what the original intent of my chosen move's first sentence was either for example, so-- it's not like the moves are gospel.

Edit: Oh! Before I go sleep, wanted to mention that I'll be away for the weekend, but can post again next week.
