Smash Ace
Sonic is the only character I have significant experience with (roommate plays him), so here's a few things that haven't been said.
If Sonic starts spindash on a 45º angle (say, either end of YI), he gains the wierdest priority, and will likely cut through your jabs, or anything else you do. Avoid, wait for the jump/spinshot, and punish.
UAir and UTilt eat his DAir for breakfast. USmash might not. Use one of these to punish, don't wait for him to land. If he's doin' it right, it's lagless.
