Not rating level wise, since you havent had time to level up...
3/10
MAJOR weakness to electricity, and you only have 4 pokemon. The moves are too one-type-centered. (Eg: Blastoise has 3 water moves; Pidgeotto has 3 flying moves). You would need to give the pokemon moves that counter its weaknesses types. (Since Blastoise is weak to electric and grass, you would want to teach it an ice move [ice beam/blizzard] and a ground move [like earthquake].
Ok.
