If you want a setup Pokemon, this is the way to go:
Toxic spikes: Good for when Pokemon switch in.
Spikes/ stealth rock: Again, good for when they switch a Pokemon in.
Rock tomb: To deal with fire types, (hmmmmm, maybe charizards?)
Rapid spin: Not really a damaging move, I use it personally to get rid of hazards such as stealth rock, sticky web, ect.

I hope this helped :)
