I don't know much about card deck games, but if you don't either then that's what this event is held for - ESPECIALLY for Imas fans!
If you're close to Little Tokyo in L.A. (a few blocks up from the LACC where Anime Expo is held), hobby shop Anime Jungle is holding a workshop by Bushiroad to show fans how to play Weiss Schwarz. Not just any deck, but the their newest one, which happens to be based on Cinderella Girls.
They're also encouraging cosplay, too, so just go to hang out. I'm about 72% certain I'll be there, too, so I'd be down with meeting any of you fine folks!
It's happening on March 19 at 1pm.

I really don't know about any Weiss Schwarz deck games - or any deck games for that matter, but of course, I'm a sucker for anything Imas. Right when the last CG G4U is released, too, they pull me and my wallet back in...
