Golem w/ Druddigon

Simple setup, wall with Druddigon if possible. Evolve a Geodude ASAP and use Brock with Golem to get Guard Press up. Very good damage and the -30 to next attack makes Golem very beefy. You could even drop Blue for another potion, but Blue can help mitigate damage for Geodude/Graveler if you're struggling to get Golem in hand or set up for a whopping -40 damage to next attack when Guard Press is up.

Leaf is nice to help swap out Druddigon or even Geodude if you have your benched Geo/Graveler/Golem ready to go.
