Eletric/Ghost
Ability: Entity Switch
This ability senses the opposing Pokemons primary type and will transform into the rotom form type that has a super effective advantage over it (for example it will transform into rotom wash if it is up against a darmanitan or pyroar, but if there is no super effective type for the opposing primary type [fairy, ghost etc] it will stay in its original form), and its ability is switched to levitate. Switching out will make mega rotom revert to its original mega form.
