I'm totally new to the game (I've only played twice), but I'm totally loving it. I held off on the Marvel stuff (not much of a comics guys), but the D&D re-theme was enough to get me buying packs.
I have the starter and 20 or so boosters (can't remember). I have 1/2 a gravity feed on the way, but it won't make it in time for Saturday. I'll bring my stuff along, though. I'll try to put some decks together tonight and see if I can jump in a game or two.
