Which pokemon should I teach rockslide to?

[gkstar1229]

I went online and I didn't get a definite answer. And tell me which move I should get rid of when you choose the pokemon. Please help!

Charizard
Wing attack
flame thrower
sunny day
metal claw

Rhydon
strength
stomp
dig
rock blast

Graveler
brick break
dig
magnitude
rock throw

Graveler removing Rock Throw or Charizard removing Wing Attack, but are you sure you want to use the TM with those?

I'm open about teaching it to any of my pokemon, but those are the ones people suggested to me.

Hitmonlee
nidoking

I'm willing to teach it them.
