I would say that the high tier should be-
Mudkip Line- Superb Choice.
Torchic Line- Also an excellent starter.
Alakazam- Beast. Best Poke in the game, no questions asked.
Zangoose- Why not?
Magnemite Line- Why did everyone forget about him? Mag is amazing!
Heracross- Why is this behemoth in High? He should totally be in Top.
