If he delays it, it autocorrects itself.
It’s not straightforward because DP cannot be canceled by 1MC in a context we’re talking about DP. The underlying problem is that you are able to super cancel DP. In other words, cancel a defensive mechanic into an offensive one and you gain from it. It does matter what you’re canceling from because being able to cancel a defensive mechanic into an offensive one is huge, it gives you advantage should it work and provides a level of pressure of its own.
The problem with that argument is that it becomes a win-win-lose situation for the opponent. If the DP hits, they got a reversal. If it didn’t hit, the super will. If the super doesn’t hit, oh well, you would have been punished at DP anyways. They have too much to gain for doing a “mistake,” whereas the punishing opponent will have more to lose for getting hit.
