Something I learned getting my butt whooped in a few MK dittos, is Ftilt, use Ftilt, spam Ftilt, love Ftilt. It goes through almost every move MK has. Other than that, the match becomes a game of who attacks first looses, simply because everytime one MK attacks, the other just shields/dodges and performs the same attack. i.e. if you tornado and I shield it, I can tornado/Dsmash/Shuttle Loop you when your done.
Also, Fair collides with Nado, letting the last two hits of Fair hit MK.
For Hype, I can't even get it to work on Dedede, can you tell me how to do that? I've gone to practice mode, put Dedede at the very edge of SmashVille (The non-moving platform) and I dash grab him, but we never leave the darn stage! Is it simply because I grab to early? Or does Dedede have to face the opposite direction of me?
