The official cards in CAH tend to be ghastly and offensive, but the game concept is sound.
With contributions from Mintywolf, I've created a large Final Fantasy themed deck. I've also created a smaller "mundane" deck because sometimes mixing fandom and real life can be entertaining. Both are PG, about the same rating as Final Fantasy games: no sex, no swear words, no offensive humor-at-the-expense-of-marginalized-
We tried to beta test them Saturday, but the third-party server that hosts custom games was overloaded with too many players and kept timing out.
So we're going to try again Monday afternoon. Not quite sure of the time yet, but I'll try to post a half hour warning here and elsewhere before I post the link to the room.
More suggestions for cards welcome. I don't suppose there's a limit, although I haven't checked.
