Toxic
Alright, make up you mind on the moveset for Milotic. This is possibly the best one though. Hypnosis has 60% accuracy, and thanks to Sleep Cause in the metagame you can only put one Pokemon to sleep in the whole opponent's party. Anyway, Toxic hits 100% of the time, while also wearing down the opponent. BP Umbreon's Mean Look to Milotic to trap the enemy, and then use Toxic wear down things like Snorlax that are usually hard to defeat.

Make up your mind man! You can't have two moves in one move slot. Too much Special Attack. More in HP and Defenses.
