Sledge -> A,A,A,B,C,D The A,A,A,B hits. The C needs to be blocked (usually is), and the D has caught everyone off guard so far. Even if blocked, you have a magnetized opponent.
After I do that twice or so, I go for the 360B for big soviet damage or a 720.
Also, pro tech:
A,A,A,A,A,720C
Never see it coming.
