Even with Eviolite on it still falls way too easily though. Garchomp plus an Altaria without Eviolite/Large Cloak, two if they do. OHKOed by Zekrom EX. Reshiram EX, possible Mewtwo EX. 2HKOed by Entei EX. Raikou EX, Tornadus EX... basically anything with the letters EX at the end takes this thing out in a hit or two. And if it gets status locked itself you just gave up a prize if you can't switch out, and even if you do anyone would gladly Catcher back up a then OHKOable EX.
A good surprise tech? Maybe. An entire deck? Too frail.
