>Mewtate>Description: Transforms foes into Mew.>Opponent is temporarily transformed into Mew while Mew is on the field. This only applies to appearance, type and base stats (sans HP), abilities and stat boosts are unaffected. This applies to all pokemon on the opposing side in double and triple battles, and is cancelled if Mew faints or is switched out.Essentially a psychic-type soak that occurs on switch-in, potentially cancelling out STAB on the foe's side, and lowering/raising certain stats. The base stat changes are a double-edged sword. Depending on the mon and it's moveset, you may benefit, or you may not.
