Welcome t' Wiichat, Twinky; no, I ain't puttin' the second y. :P Hope ya enjoy the forums.
My Wii's semi-busted and refuses to play dual-layer discs, so unfortunately I can't Brawl ya. If you want to do some battles on Battle Revolution with just rentals however (of course I wouldn't use the ones from my game, that'd be horrifically unfair lol), I wouldn't mind diggin' up my disc from the piles of game cases for a few rounds.
... I really hope we get a Battle Revolution-esque game on the Wii U for the Generation 5 Pokemon games (Black/White, Black2/White2). If we do, that'd explain why the Wii never got Revolution 2 for Black & White 1.
