I think the coolest impromptu trick is Double Exposure by Asi Wind. The guy's a genius. And when you ask a spectator for a phone, they become really curious. After I'm done, I walk away like a boss whle they're still looking at the picture. XD
I have recently been purchasing decks, but have no idea how to deal with the sticker seal. What do you guys do? Cutting across it doesn't let me use the thumb cut... and I can't take off the sticker because it rips and looks ugly..
