No Competitive Ability
Clear Body / White Smoke
Heatproof
i like to let people know my thoughts so, here goes
my first option by far is no competitive ability, I feel like water veil is enough and I don't really think we need anything else.
that said, if we do need something it's the ability to not get ruined by intimidate, so Clear Body is cool for that reason
Heatproof is ok for checking fire types, but thats all; korski's right that it halves burn damage, but the damage is bad mostly for nullifying lefties, the extra damage being more of a bonus
early bird is basically just giving CM the option of early bird rest, which i don't like since we have burn/psn immunity, meaning recover is ok, and early bird rest lets even lando-t / excadrill / terrakion switch in for the OHKO, without worrying about a predicted Scald to the face KOing them
