Holy ^%$# This Might be Awesome!!!
I just found This on Gamespot. It's called "Magic: The Gathering - Tactics" . I haven't played "Magic:The Gathering" in about 5 or 6 years. Mostly because I couldn't find the time to get together with friends when compared to all of life's other demands.
If they do this game right it could be really, Really awesome. It sounds like you build a Wizard and level him up then take him Online to Tactically Battle another Wizard. It's NOT a card game, but a Wizard's Duel type game Based on the Magic:TG system and in it's universe. Definitely worth watching IMO.
