When it Rains, it Pours!

Everybody knows Gholdengo ex can deal essentially any amount of damage it wants with its “Make It Rain” attack—well, that is, as long as you have enough Energy cards in your hand. In this puzzle, you find yourself backed into a corner against one Charizard ex and one Mega Charizard X ex. Your opponent has also attached a Hero’s Cape to their Mega Charizard X ex, putting it at a massive 460 HP! You have already taken 3 Prize cards and have 3 left to go. Can you win the game on this turn?
