Aria and Wiccan. Aria's the tank and Wic's the hard hitter. Why is this you may ask? Sylveon and Umbreon have the exact same sp Def stat...but umbreon is a dark type. Fairy is super effective against dark AND dragon so it only makes sense.

Headcanon voices,
Duchess for Wiccan and Marie for Aria, both voice headcanons are from Aristocats.
