I'd much rather have Eviolite than Dark Claw. This deck is meant to tank, and you have Hydreigon for the situations you outlined. Hydreigon's actually better, because you only need one snipe on a Keldeo or a Mewtwo.To protect from garbador, why not play 2 scrappers instead of clutter with energy switch? Have you played around with dark claw at all? I really like it. After playing around with it, I like that I can snipe twice on a keldeo or a mewtwo, then catcher it and dark claw for a OHKO. Then scrapper doesn't make a waste of a card.
