Hey! Yep it went through as a PM too. Well, of course see how it actually works out, but I don't think it's too big of an issue. Rock Slide isn't quite as common as say two years ago (mostly because no Landorus-T). You will see it on other Aerodactyl or Garchomp, but thanks to spread damage it isn't OHKOing much. You do have your a resistance as well at least. Nihilego and Gigalith are the main 2 rock types I can think of off the top of my head. Nihilego could cause some trouble to half your team, but Garchomp (thanks to AV you don't have to fear HP Ice too much) and Pheromosa handle it well. Gigalith could be more of a problem, but really only IF Trick Room goes up (which you seem confident in being able to prevent). Without Trick Room, you have a few checks to it to deal with it.
