Corner(stone)-ed!

Well this is awkward... You are running Joltik Box vs Mega Absol Box, and your opponent left their Cornerstone Mask Ogrepon ex in the Active Spot. You are running out of options, since Ogrepon cannot be damaged by attacks from Pokemon with abilities. You are running out of cards in your deck, and your deck is full of Pokemon WITH abilities (excluding Joltik, but it doesn't even do damage). You need 2 prizes to win, so Munkidori doesn't matter here. We need to find a way to knock it out on this turn, else this game might end not in your favor!
