>>20835643Probably Espeon, just because Psychic is so OP in practical terms. We could fly pretty much everywhere with its telekinesis, though that probably wouldn't be necessary if it can just teleport. It's also apparently quite intelligent, I believe, so we could probably have some interesting and mentally intriguing mental conversations and debates.
It's also my favourite of the Eeveelutions, followed closely by Vaporeon, so it'd fit my aesthetics as well.
