Wow I never knew that after I hit a shield with Wolf's Bair that I laser. Does that apply to any and all American Wolf players? If I Bair after I hit a shield with Bair does that make me as good as Gaki? =)
There's lots of crap to do after you hit a shield with Bair. If you think they're going to roll towards you, you can just stay there and grab. If you think they're going to roll away you can boost smash (very satisfying to pull off), if you think they're going to stay in their shield you can grab them. If you think they're going to jump you can do any attack (Bair, Fsmash, Dsmash, Fair etc). If you think they're going to spotdodge then you can pretty much do whatever (Wait and grab, Jab, Charge Dsmash/Fsmash/Usmash). If you think they're going to grab, then punish the grab.
But, of course, ignore all that, you should use Bair after you hit a shield no matter what, duh. =)
