I'm not sure what the best way to do this is (or if this is already what you're planning to do), but it might be fun to just vote on grammatically coherent and functionally reasonable phrases once we get to non-vanilla text. So the first poll might have options like:
"You may discard", "Trash", "Gain", "Put a card from your hand", "Play a card", "Take a coin token.", "Reveal", "Look at", "Each other player", ...
Then if "You may discard" is chosen, the next poll might have:
"a", "any number of cards.", "up to", ...
You could probably come up with better options if you put some work into it, maybe by comparing each phrase with phrases that follow it on official cards. After the end of a sentence, each poll should have an option to end the text. Or maybe just include that option in every poll (given it leads to a grammatically functional card), and then adjust punctuation to accommodate the text ending unexpectedly.
Alternatively, we could maybe vote for functions of the card and then revise details later. For example, we could decide we want a terminal draw card that trashes n cards and gains a card costing up to x. (We would decide that in three separate polls asking about different functions the card should accomplish, and then a fourth poll where we decided we were done choosing functions.) Then we decide on how each of those functions works; for draw, we might have options like "+1 card", "+2 cards", ..., "+1 card per card in your hand", whatever other crazy options people want.
I voted victory card before I actually finished reading the post, so I didn't realize it would be a pure victory card in that case. I like victory cards a lot, but actions are probably more fun to make with this process, so I'm glad action won. I'm surprised only two people voted Treasure.
