You should also have a Mimikyu on your team, courtesy of Disguise, or have Rest and Chesto Berry, Protect, Detect, etc. This is the first of Maxevil's Death Battle to be a Battle Royale and the first to pit 2 or more characters from the same series against each other; the next three episodes are the W.I.T.C.H. Have a Pokemon that have moves that can hit multiple Pokemon at once (e.g. Dazzling Gleam, Surf, and Earthquake.) Also, go to the moveset checker to see what Pokemon have the most coverage.
