Looks cool. A couple questions:
1) Is he supposed to be able to use Cowabunga! multiple times a turn, or only once per OM reveal?
2) What exactly triggers the "the attacking figure's turn immediately ends" part in Lock and Strike? It seems like it's supposed to be the excess shields, but I think it could also be easily read that he ends the attacker's turn even if he doesn't get excess shields (assuming their attacking with an adjacent normal attack of course).
Otherwise,
