My point is every team in OU can consist of poison immune pokemon, so you just wasted 2 turns when your opponent could have Gyarados, Blissey, Flygon, Celebi, Skarmory, and Rotom-A.
Natural Cure on Blissey/Celebi wouldn't help too much though, as it's the same as if they didn't, as they'd be re-poisoned/get damage once they switch in again, while if they stay in, they get crippled.
But in NU, Beedrill, Dustox, Victreebel, Swalot, etc. roam, as well as stuff like Zangoose (Immunity), etc...
