Best ability ever: Gamble.

So I'm thinking about a new character, I know there are a few gamble kind of dudes in the Marvel universe.

All his abilities are a gamble. The more AP in given color you have the better the attack could be.
Let's say you have 10 red AP. That's enough to trigger his nuke attack. Would you...

Spend all 10 AP for a 7000 damage nuke at a 50% hit chance?
Spend 5 AP for a 3500 damage nuke at 100% hit chance?
Spend 7 AP for a 5500 damage nuke at 75% hit chance?

From here on there are endless opportunities in healing abilities (heal one team member for 25% or maaaaybe try to heal them all at 25% at a risk?)

Stuns; spend a bit of your AP for a 100% 2 turn stun or spend all AP for a lower chance of a 5 turn stun?
