Just what the title says! I played at PAX and visited the booth all three days (totally fell in love with the game, and every day had a different shirt), so I ended up with a couple extra WW cards. Since I'm fairly new, I've only unlocked Ivy and Wonder Woman. I've seen a few people asking about the WW skin, and I'd love to trade for Crisis Coins, or possibly Flash Point Doomsday.
So far, I have Greek Goddess Wonder Woman, Classic Poison IVy, and Arkham Origins Joker
I have significant feedback on eBay, GameTZ, and CAG, so feel free to message me privately and I'll verify my feedback for you before we trade.
