Any of you ever hear of urban Rivals from numerous ads and crap going about online? I thought I'd try the game a while ago, and I love it. I'd highly reccommend this if you're into TCG's and you dont want to spend (real) money on cards; You could grind ingame currency and buy really powerful cards. You could also level up your characters, like in Pokemon.
