The easiest way to get a Rhydon is by Pokemon XD Gale of Darkness nd in there is a Shadow Rhydon in the game and after purifying it you can trade it to Ruby, Sapphire, FireRed, LeafGreen or Emerald and then if you want you can migrate it to Diamond, Pearl or Platinum.
In indigo, you don't need hold items to evolve them through trade. Just trade a Rhydon. Your welcome :P
You defeat Giovanni (which is also the Team Rocket Boss). He is in Viridian City, and his Pokemons are Rhyhorn, Dugtrio, Nidoqueen, Nidoking, and Rhydon.

It's pretty good, but you should really get Fire Type Pokemon, because they will have the same type attack bonus, so they will do +50% damage with Fire Attacks. Also, You should try removing Rhydon and trying Diglett (it's much faster than Rhydon). Remove Butterfree too and Get Psychic or Ghost Pokemon. They will be valuable when you go into the Pokemon League.
Trade your rhydon while it is holding a "protecter".
Rhydon evolves when the "Protector" is held and the Pokemon is traded.
