>>41333639you're giving an improbable argument in the first place with that sort of criteria demand
you don't ever "switch in" to a diverse powercreep bazooka attacker, you take the fucking L to whatever it blows up and then force their swap or revenge kill it
with smogon going full babyshit mode and crying for arena trap/shadow tag bans this early into the meta, there's no true 'switch in' counters for things like this. a banded g-darminitan isn't going to just sit there spamming an ineffective move vs a counter until it dies, it's also going to switch out to counter your counter etc etc
tl;dr - you're asking for something that isn't a thing, what you want are reliable 'revenge killers' - even resisted hits from gi-darmininantan are going to blow a huge fucking hole in whatever you raw swap in front of it
