Hey i know its about stats and stuff, but i would change some pokemons:
Alakazam hard
Charizard hard
Exeggutor medium
Farfetch'd medium
Gengar hard
Gyarados hard
Lapras medium
Nidorina easy
Omanyte easy
Vaporeon medium

It better suits, for example every starter has hard at last Evolution, but Charizard is medium. Eeveelutions should be similar to each other too etc.
Maybe other players will also say something about their thoughts

gyarados does not have to be in medium since its stats are really the highest is not the same a gyardos level 40 than a starmie level 40
