Playing the game with an underleveled team

Just to let you know that Umbreon is basically a Tank with average HP (base 110 def and base 130 SPDef) (It managed to live a lv 8x Fully EV and good IV Alakazam's Focus Blast, Lucario's Aura Sphere, and my Ampharo's Signal beam..), so if you want the OHKO, you gotta use physical Bug/Fighting attacks.

I can kill it with a third round rollout in a single hit.
