Tsutaja's evo: Kind of dissapointing, Imo. High speed, and decent defenses, but offensively it kind of sucks, Imo.
Pokabu's evo: Great HP and Atk/ SpAtk, bad speed. It might be OU, since it will probably be able to take some hits, and hit back hard, but if it has a bad movepool, then... (But I think it'll have a good movepool)
Mijumaru's evo: Good stats overall, except the speed is a let-down. Good HP and defenses, great Atk/ SpAtk, but bad speed. It's movepool is good, though. It has access to Swords Dance. I think it'll be UU.
