If you have the cards and want to stretch some creativity, try an Asmodeus deck. He can basically freeze everyone at 6 resources, so you can recruit Dracula-6 to "counter up" on opposing characters, eventually becoming a fearsome beatstick (and usually starting with a strong attack via Mist Form and/or Black Magic). I don't have a decklist, because this is a deck a friend of mine made, and it was a great idea and really aggravating to play against. Our games typically go to turn 7+, and I never had backup drops for characters of cost 6+, so I'd be sitting there with just one big guy and have to drop out a smattering of lower guys while looking forlornly at my game-enders in my hand. I'd be throwing myself at Asmodeus each turn, but Drac would still be feasting away...

He later combo'd it with Anti-Matter, for the From Qward With Hate angle, to continue to forcibly limit everyone's resources (and character count).

A friend and I played a game of sealed between DOR and DSM packs just yesterday. It was great fun, and anyone who wants to spice up their gaming should try it. I try to run regular sealed events at Trilogy, where everyone can just buy 5 packs of whatever set they want and go to town. That is always a lot of fun!
