Rulings

From the Super Slam release notes

Jaws of Victory’s first ability triggers when it resolves on the stack and becomes an attacking card against a hero. Whether or not you have less than that hero is checked when this triggered effect resolves. If you have less than them, the crowd cheers you.
Jaws of Victory’s second ability generates a conditional continuous effect that is always checking. If the crowd hasn’t cheered you when you attack with this and then the crowd cheers you, this will get go again.
Go again is checked during the resolution step. If the crowd hasn’t cheered you this turn but then the crowd cheers you before the attack’s resolution step (i.e. after damage is dealt, but before moving into the resolution step), you will gain an action point from go again during the resolution step.
You don’t retroactively get an action point from go again if you’ve passed the resolution step and the crowd hasn’t cheered you, and then the crowd cheers you later in the turn (e.g. after you’ve played another attack, closed the combat chain etc.)

Keyword notes

Go again - Go again allows multiple actions to be played in a turn when usually playing an action with use up your action point, and therefore end your turn. A card with go again gives the controller of that card or activated ability 1 action point when it resolves.

When an action with go again resolves, its controller gains 1 action point.
Multiple instances of go again on the same card or activated ability do not stack. If a card or activated ability has multiple instances of go again when it resolves its controller gains 1 action point only.
If an action with go again does not resolve, its controller does not gain 1 action point.
You cannot reveal a card with no to Belittle. The card must have a value to its power that is 3 or less. (0 is a value)
