>>23390143Hydratation set is outclassed by Go.o.dra, also makes you unable to take advantage of wish and heal bell without being retarded.
Water Absorb Cleric is better, but scald will be your only offensive option. Umbreon has foul play, which can remove almost every Dragon/Swords Dancer in the game with a uninvested Def, Sp.Defensive set.
Syncronize and Inner Focus prevent umbreon from beign Paraflinched
Fighting types are losign ground due faries everywhere, especially during Slash test.
Bug-types are Bug-types.
Faries are troublesome so Umbreon works best along a poison-type or steel-type.
I belive Umbreon is better, I have good experience with it in OU. Still, all depends on your core team.
