Uh, we are talking about if we should ban Deoxys-S or not and whatever has to do with that. Nothing else.What is wrong with Magic Coat Deo-D? A moveset of Snatch/Magic Coat/Recover/Toxic might get walled to hell and back by steels and Gengar but it is hard to destroy. Snatch allows you to steal Heal Bells, Soft Boiled/Roosts, Dragon Dances, etc and very few moves that aren't Choiced will do over 50% to Deoxys. If a move does more, you know it's banded or Draco Meteor (which it can outstall if enough health remains). Snatching Dragonites D-Dance and Toxic on it is fun or if it's banded, wall it with Skarmory and set up Spikes. Without Spikes and Stealth Rock Deoxys-S is useless, the Life Orb set will just kill itself through Recoil, and the Dual Screen Set...I'm not sure if Screens can be snatched but it can at least steal any set up moves.
Not even Adamant Choice Band Tyranitar can ohko and if it's not banded, you could just toxic on it and stall it out unless Crunch lowers it's defense and on banded, send in Terakion. It can even beat Tyranitar with Toxic if
they lock themselves in Pursuit. Deoxys-D is seriously hard to kill and although not good on teams that want fast offense, on a stall or mixed he's amazing. I'm surprised one of the best walls available isn't used.
And that doesn't even do what Deoxys-S does, so that makes it even more redundant.
