Trivia

Different total numbers of cards

Jay would just repeat to me (if I asked), that I should make the expansion as good as it can be and then he'll deal with what cost or whatever that means. But I do nevertheless take into account the tokens/mats; they're an extra cost, and it's nice if the expansions are the same price.

There's no special time I decide the size. I work on the set and gradually have more cards and more of an idea of what tokens/mats/landscapes/non-supply cards are in it. At some point I feel like, this wants to be this many cards. These days the size tends to be as large as it can be while including the other components.
