Here's an idea for that pesky prime you got two many of:
Meganium prime + Dodrio for free retreat. Its got a lot of HP, so when you're about to die, move the energy to a meganium/baleef/chickorita, retreat meganium, seeker it, and plop the evolution right back down.
Meganium + expert belt does 100 damage and has 170 HP so it should be pretty good as a tank. And you can use metapod to cover your weakness if needed.
