Aparajita. In Ice-monotype, Kyurem-White is allowed. Use that. Or nothing.
Without any intention to sound rude, offensive or whatnot, there are some Pokemon that are mandatory for a good Ice monotype. I can nominate among them Kyurem-White, Avalugg and Mamoswine. You can't make a serious team without them, which limits creativity at depends of efficacy.
Articuno means a crippling rocks weakness and this alone justifies not to use it. It can't make use of its wowing 125 SpD base because of horrible typing. Its negative trait take on its positive, so this is why it should not be used on a serious team.
I see what you want to do with Stallrein, but I would try Toxic > Roar for making it even more annoying and naturally forcing switches. This is part of a manipulative loophole since Walrein is a capable staller; I've seen it once while spectating a battle last for 32 turns almost untouched.
Swap Articuno for Kyurem-White. You ought to go for the scarf because you need fast offensive presence that's immediate; Cloyster and Regice being setup sweepers and Mamoswine and Walrein not special attackers, the slow Abomasnow is not capable to play the special attacker role in a team alone.
I would equally consider switching Regice to Froslass for some hazards that can always help any team.
Go for:
Froslass @ Focus Sash
Ability: Cursed Body
EVs: 252 HP / 4 SpD / 252 Spe
Timid Nature
- Spikes
- Taunt
- Destiny Bond
- Icy Wind
Naturally, it's a lead so it's designed to set up Spikes and force switches in some cases. Icy Wind reduces speed and avoids being Taunt-bait. Amusingly enough, Froslass uses Taunt herself, so make sure you're the fastest.
The changes you made so far:
-Mega-Abomasnow
-Toxic > Roar for Walrein
-Regice -> Scarfed Kyurem-White
-Weavile -> Mamoswine
-Articuno -> Lead Froslass
I think that's it. Feed me back!
btw, nice answer Shining. +1
