Procession isn't as bad. If you Procession a duration, the Procession stays in play to remind you that you get two of something, and it's not too tough to remember what it was. But that doesn't happen with this card. You end up with the Duration card in play next turn, which is not as unusual as a Procession in play, so it's easier to forget that it was played more than once.
My question for you is, what is the design goal for this card? As it is right now, it fills about the same niche as Throne Room by letting you play an action twice. Unless there are other pieces that are missing, this is weaker because it requires you have TWO extra actions (one to play Believer, one to play the card that you take back) and it is a bit more flexible (you can split up the two plays instead of getting them back to back).
From a gameplay perspective, is that flexibility really worth using up two more actions than TR? I can't think of any common situations off the top of my head. Menagerie, maybe? Eh.
From a design perspective, is the subtle difference from TR enough to warrant clunky wording and high potential for confusion?
that's the kind of stuff you should post
here. i mean, i haven't even specified how the card works, how much it costs, what it can do, i was just asking about the wording
but alright, the idea of believer was to be a weak throne room variant for 2$, with more flexibility because you can also topdeck the card (I didn't mention that here, because it doesn't matter for the wording issue), and it also has an on-buy effect. but man, it is
strong. so strong you would never guess it just by looking at it, it may be the strongest 2$ in the game. and it's also my personal favorite, I love it, it's complex but incredibly powerful, so yea, it is absolutely worth any issues it might have.
and procession can be even worse, if you play a procession chain, like procession - procession - wharf - wharf - procession - wharf - wharf. now you have +16 cards next turn and not even a single card to remind you of that.
The game state is unaffected by its effects that it has not had yet.
that's neat. i'm not worried about sheme, my only concern with that wording is that it'll look confusing to newer players. still, it's worth considering, maybe i'll do it
