What you do is when you attempt a finisher, the referee will roll a dice. The person attempting the move will call "odds" or "evens" and if what they called is rolled, the finisher connects and they can immediately go for a pin.

If the other is rolled, the person the move is be attempting it on automatically gets to reverse. This doesn't count against the two reversals you're allowed per page.

This is so people don't reverse every finisher.

Ex: Justin attempts a So Cal Slam on Knockout. Evens.

If evens are rolled: Justin can go for a pin witohut waiting for a response from Knockout.
If odds are rolled: Knockout automatically gets to reverse and can attempt another move.
