I don't think that deo-s was banned just because lo cleaner kills everything (quick mention: I saw Psycho Boost ohkoing rotom-w) it was the metagame that he ''created'' that banned him.
I mean, am I the only one who rage when I see deo-s+5 setup sweepers in team preview?
Of course, HO is a plyastyle, considered by many ''fun'' but everytime I saw ho teams with deoxys-s, be it spiker or screener the match was just a complete mess, at the same level when drizzle+ss were legal. sr+spikes created excessive pressure against opponents team ''hey look I have Starmie, is so good as a spinner'' Yeah, so let's see you use orbmie with the hope to spin away hazards, look gengar came in, no prob i'll kill him with Hydro Pump! (hpump miss- oh wait irrevelant) Ahà! Take that bitch, uh, Rotom-w entered the battle, oh man it's scarfed it's obvious, damn you I hate you volturn (BAN ME PLEASE) with ''hazard deo'' Now i have to switch, I seriously hope that later I can spin this motherfucking rocks, and not entering cbzor bullet punch ohko range''
Starmie is perhaps the best spinner in ou atm, because on the contrary of forretress, donphan and tentacruel it doesn't give momentium to the opponent, thanks to his/her great coverage and excellent speed, sadly it's still not enough to warrant a spin.
What happens? Volturn, or Scrotom, call it whatever you like abuse the sr and 1 (or more) layer of hazards, WITH YOU INCAPABLE to protect yourself, and sooner or later you'll be strained by the ''residual'' damage.
I don't even want to talk about screens, nor screens+smashpass, not even funny srsly, even though deo was banned I hope that Smogon in the future will look and take a decision about smashpass, anyhoo...
The biggest point that sets deoxys-s from azelf, it's not only the coverage (superpower any1) but the greater speed, this was already explained in the topic created by jabba, Azelf and the like will have problem surpassing things like scarftar, and trust me, scarftar in dppt wasn't used only for latias, if things turns out to become like the ''lead metagame'' in dp, then surely he will come out on top, in the usage list, aerodactyl and things can also taunt it, and who knows, we MIGHT see things like scarfrachi again, only time will tell, about the lo cleaner, imo it's not a quesiton of ''it's powerful like thundurus this motherfucker'' it's more like:
''Ok I'm going to send in mah tyranitar who will clean this aline things up
What in the world superpower omg, damn you, now i'm 5 vs 6, and nothing will stop him setting up hazards''
''GO STARMIE SPIN THIS BITCH, what the hell is this, thunderbolt/thunder? IMPOSSIBLE, how am I supposed to spin now?
''wtf, I though that it was the standard sr/spikes/taunt/superpower, ugh, sorry gliscor...
Btw, lopsycho boost who destroy Rotom-w fits in, too.
Anyway, curios to see how the metagame will develop now, and also for the next suspect, heh
