^ Well, nothing really does. But at the end of the game it's sorta unavoidable. Decks usually only run a 1 or 2 Night Maintenances, save Beedrill... and I highly doubt any of them will waste it on energy. If they do, congratulations, you just disrupted your opponent. Now hope Flygon Lv. X continues to discard unretrievable Pokemon as well as energy to continue to fuel Vibrava, in between every turn.
Really, Vibrava will very rarely attack with more than 1 prize left. If there's like, 5 energy in the discard pile, you're already doing 100 for 1 Energy. You can prolly Warp Point for the final prize, too, because late game not much will have anything < 100 HP on the bench. Vibrava only has 70 HP, so you're really only trading prizes mid-game (Sometimes you have to, however), but you'll unlikely hit for a whole lot of damage. Memory Berry does fix the HP issue, though.
