Edit: According to a reader at joystiq the cards are
"Eggplant Wizard, Fiends Cauldron, Skyscraper Club, Firework Cannons, and Minos, along with possible random packs."
Edit 2: Just picked up a pack. All I did was ask about it and he asked if I wanted to try the game. I told him I already own it and he just gave me the pack. There were a couple people instore but not for the event. They had a stack of around 100+ on the counter.
The cards in my deck were: Eggplant Wizard, Fiends Cauldron, Skyscraper Club, Firework Cannons, and Minos.
I'm not sure about the random packs, forgot to ask.
