OHKO moves weren't banned because they were broken they were banned because they take no skill to use and bring an extra level of luck to the game.
It's sad that a Pokemon with such great defensive potential has to be weak to Stealth Rock... Articuno can be a beast with no SR.
So... Would this work?
Articuno @ Leftovers (DW: Snow Cloak)
252 Hp, 200 Def, 52 Sp. Def
Sky Drop
Protect
Toxic
Roost
After the turn of Sky Drop, Snow Cloak gives a chance to rinse and repeat without taking damage.
Its sad that people like you are around....Not really, it gets dominated by Tyranitar, Rotom-W, Scizor, Ferrothorn, Heatran, Jirachi... wait a minute, I just named half of the top 10 OUs. No, Articuno is a garbage pokemon and should rot in NU where it belongs.
Really just waiting till gamefreak changes the type chart around, Ice/Rock got screwed over so badly, particularly with the style of pokemon Gamefreak likes to make those types (Defensive). (I mean seriously why does Ice only resist Ice? Heck if it resisted what it hits SE it would be fantastic)
That's the point, Ice was made to be the glass cannon type. It's a shame it's usually given t defensive or pure-type offensive pokémon, but eh. One day.
ghost/steel with levitate will be the best defensive poke ever
Wow guys.... how about articuno talk more? Because that sounds pretty dandy to me!!!
It's sad to see Articuno so bad, I've always liked it as a pokemon but its typing is just too poor to be effective. When it comes to Toxic stalling Moltres does better due to its Fire typing, and offensively Zapdos is better because of it's Electric typing. The best I think 'Cuno could pull off would be a Specs set to blast through cores, maybe running Snover on a team so it can fire off STAB Blizzards? I haven't touched RU in quite some time so this is probably going to be far off.
Fire type over Ice type isn't that much of un upgrade you know. And Articuno has noticiably better defenses.
The only reason Articuno is "bad" is because it's been mercilessly stripped of its niche (Mind Reader + Sheer Cold).
Oh yeah, that's not-competitive, luck-based and broken because we have tons of data clearly showing Articuno dominating the metagame if it was allowed.
Articuno is one of the many cases that show that our current banning system has a number of flaws in it.
I think you guys might find my RMT intresting, especially regarding its DW ability:

I love Articuno, and even though the chances of SR getting banned here is very slim, I'm hoping that in the next gen Troll Freak would nerf it, and allow Rapid Spin as a TM. Also, expand its bloody move pool as well.
Without snow cloak hax, moltres does this moveset better than articuno on a hail team, resisting fire, fighting, and steel (not really, just bullet punch). Moltres also has naturally higher SpA, so he can't be turned into setup fodder as easily. No 100% accurate blizzard though.
I feel as though articuno desperately needs defensive tools in order to be worthwhile. As a wall, he doesn't exactly do anything outside of roost and toxic. The bad typing would be so bad if he was able to set up on threats, effectively phaze, had a good defensive ability, etc.
