Off my head (ignoring staple-moves) top-9:
66K - Awesome, mixup BS-throw/1K on hit. Puts player on CH (BS Throw will work fine if you expect WS B-move. Risky though). So good.
4A - Good on block, goes BS.
1[k] - Ofcourse
2A+B - Awesome move. Also great oki.
6:6B - So good punisher. Honestly, I think people need to get better at punishing. I see top-players not even punishing Asura Dance.
A+B - Goes under High. Damaging. Safe. LOVE this move. Underused.
BS 1A - Not to spam, can be blocked on reaction. Great though as it has awesome range, damaging and make Voldo evade so many attacks.
BS Throws - One of the reasons I picked him. LOVE his stepping. Evades so good.
Honorary:
4K - Good move to get into stances.
3B,B - Not safe, but almost to abuse when your opponents Soul Gauge is low.
CR B_K - CR B for RO. Good oki-moves.
BS FC B - For BS-ROs
