It's ok- most people use sucker punch anyway. I wish there was a warning that explained why certain things aren't allowed. It would make move selection easier when you have weird gen-restricted movepools like Stunky does.Alright, sorry should have extended that. I assumed sucker punch and that was wrong of me.
Defog is a Gen 4 HM and cannot be obtained on Stunky (or Skuntank) any other way, so it is incompatible with Play Rough.
Back on the mons!
Froakie is amazing for setups. Just be wary of predicts who will blast you with elemental attacks knowing you probably have Protean.
Stealth rock is heavily abused from all users so far. Dwebble and Onix are pretty common.
Defog is neglected. Consider using a water type as ground/rock/flying are everywhere.
Koffing is a great wall against anything without psychic moves. Explosion can be added in case of actual threats and clear smog is great against boosters.
Aipom always uses fakeout and power-up punch. You're not likely to see anything else.
