Hello, I have been running a mono-ice team with Kyurem-W and I agree with what scpinion said: Kyurem-W is unhealthy to the metagame and should be banned.
While it plays very differently from Talonflame, the end result is the same: Kyu-W is extremely powerful against several types, therefore discouraging their use.
On top of that, besides Mono-Fairy, there is no monotype that is completely safe from it - even mono-steel, fire, rock and fighting, ice's main weaknesses, need to be extremely careful around it (mono-fairy has AV Azumarill and Sylveon as reliable answers).
Mono-ice still has issues against fighting (Scarf Kyu-W is almost mandatory here), fairy (if you give Clefable a chance to setup it can 6-0 the whole team by itself) and bug (the best bugs happen to have a secondary type that gives ice issues, such as Scizor, Volcarona and Genesect).
Everything else is either neutral or in ice's favor as long as Kyu-W is around.
Kyurem-W is very versatile, being able to run Scarf, LO and several Substitute variants. Choice Specs, its trademark set in ubers, is just overkill in this metagame so it's not needed. I personally ran a speedy and offensive Sub+3 attacks set until I hit 1500's on the ladder, then switched to Scarf. My team was the same as scpinion, except I ran LO Weavile instead of Cloyster, and my Rotom-F ran a SubSplit set with WoW and Discharge.
The types Kyurem-W wrecks aren't just the ones scpinion listed (dragon, poison, flying and ground), but also
grass,
electric and
normal (requires Knock Off support for Chansey).
I have seen people going to great lenghts not to have their teams utterly dismantled by Kyu-W, including but not limited to:
Eviolite Mantyke,
Eviolite Lilleep with Mirror Coat , AV Armaldo, AV Victini, AV Walrein, Scarf Landorus-I (not a gimmick, but significantly less standard than LO sets), Specs Moonblast Whimsicott and best of all
Focus Sash Ferrothorn. And despite these incredibly specialized checks Kyu-W was able to come on top most of the time.
Turboblaze is extremely powerful in Kyu-W's hands, as it can OHKO Sturdy mons like Skarmory and Forretress, damage Heatran with Fusion Flare (breaking its Balloon in the process) and bypass Levitate with Earth Power (mono-electric, mono-fire and mono-poison in particular are extremely reliant on that). Its Ice/Ground/Fire coverage not only is unresisted thanks to Turboblaze, but also happens to have incredible SE coverage (
http://pokemondb.net/tools/type-coverage). Like its brother Kyu-B, it doesn't even need to run its Dragon STAB to be a killing machine.
It's also astonishingly bulky: even with minimal EV investiment in HP it can comfortably live powerful hits like Scizor's CB Bullet Punch, Victini's V-Create and Heatran's Flash Cannon. I distinctly remember Kyu-W managing to live M-Mawile
and Bisharp's Sucker Punches, OHKOing both of them in the process.
I'm also leaving this gem here:
0 Atk Ferrothorn Gyro Ball (150 BP) vs. 0 HP / 4 Def Kyurem-W: 336-396 (85.9 - 101.2%) -- 6.3% chance to OHKO
This is against
Choice Scarf Kyurem-W.
When addressing Kyu-W's flaws, we need to be honest here: it's not Kyu-W that is severely flawed, it's the rest of the team that can't fully support it the same way other monotypes could. Unfortunately mono-ice lacks reliable Heal Bell, Wish, Healing Wish, Sleep and Baton Pass users; if it did Kyu-W would be completely unstoppable against every monotype.
Yet monoice has just enough support to let it become a huge threat against most of the metagame. Those replays above clearly demonstrates that mono-ice has turned into an entry hazard war with Kyu-W blasting holes whenever it gets the chance.
The question now here is: if a single pokemon can destroy several monotypes by itself but it's not strong enough to let that type (ice in this case) overcome its major weaknesses, can it still be considered broken?
I'm asking this because I have a hard time believing that Talonflame could easily sweep mono-rock, mono-water (Suicune, Rock/Water types, Rotom-W), mono-steel (Heatran), mono-fire (Heatran and Rotom-H) by itself, yet the fact grass, bug and fighting were almost completely helpless against it was reason enough to ban it.
The same can now be said for Kyu-W against grass, electric and the other types mentioned above. If we're going to treat both the same way then it's pretty clear to me that Kyu-W should be banned.
