the support set u posted is really really bad sure it can stops things from setting up, but it cannot threaten anything stealth rock is just bad on most arceus formes as it limits what it can do the set is also complete hazard bait, which is bad news for any wall in bw2 (eg lugia who hardly saw any use among good players because of this) wow is mandatory on support steelceus so u can actually do something except roar away threats it also means hazard stackers cannot get in scot-free as a burn compromises their ability to wall other things so changes should be sr -> wow btw the reason perish is good is not because it can stop bp chains, although it is a nice perk, but because it can stop last mon sweepers for stall and acts as a win condition, so u might want to change that in the description ~ sd set looks good sub doesnt really deserve a mention on cm set, as it is already immune to toxic, which is the main reason people would run sub on cm arceus
