Golem: Rock vs Ground moves

Rhydon is better than Golem if you want a ground attacker

However regarding to your question, unless i dont have anything to use the TM, i would if i needed or wanted to have a rock attacker because as rock attacker golem is pretty solid but needs both quickmove and charge move rock attacks

and have to take into consideration your biome, in mines i can farm geodudes so easily that i would just try to get a rock golem insteand of using a TM on him, especially when i haven received a single tm in 10 raids

Keep it man. Why waste 2 tms, get another golem. Double ground hsd its uses.

Double rock beats MS/EQ any day.

Dragonite, Gyarados, Muck, Weezing and Arcanine all vulnerable to him.

If you have 1 ground and 1 rock move, change the ground move to rock.
If you have 2 ground moves, just use it as a ground attacker in raids.

use fast TM on it now. Wait for Charge Tm for latter (legendaries???) or if you lack 1-2 seconds to solo a lvl 3 fire boss.
