Slush Rush abuser for fast utility in Rapid Spin and Knock Off for hazard and item removal, respectively. Iron Head for stab and coverage against those fairy
godparents and Rock types, Earthquake to cover some of Ice’s weaknesses.
I mean what’s there to say about this thing? Its offensive capabilities are required on every Ice team. SD to put games away, Crunch to exorcise Ghosts and put Psychic types out of business, Sacred Sword because it’s the 5th Sword of Justice to cut Steel like he’s Zoro from One Piece and make Normal types Abnormal, Ice Shard because sometimes being fast isn’t fast enough. What is this mon, man?
Aurora Veil to make the team bulkier and pairs will with Snow Warning. Freeze Dry to hit Water types hard, Moonblast for Fighting and Dark types, Encore to catch someone lacking for doing the same thing over and over so you can use it to your advantage (or downfall). Max HP so you can get more turns out of Ninetales and Icy Rock to maximize Slush Rush uptime for Sandslash and the bulk for the team overall.
Your hazard setter and it helps absorb a few Fire moves for Ice. Earthquake for STAB against Fire, Rock, Poison, and Steel types. Smack Down to bring down those metal birds. The EVs allows you to make Body Press from Corviknight a 3HKO outside of Snow and a 3HKO from Skarmory’s Body Press while under Snow. Also avoids being OHKO’d by Ogerpon-Hearthflame to EQ and Ice Shard Hearthflame.
White Herb is better than Focus Sash because of what Snow does for Ice types. A massive 180 base Def to be further boosted by Snow allows it to setup Shell Smash against a large portion of the physical attack cast of mon in the tier. Icicle Spear for STAB and Rock Blast to cover Flying and Bug types. Ice Shard to avoid being revenge killed and to tag faster Choice Scarf mons like Latios, Dragapult, and Roaring Moon.
I was debating whether to put HDB or Specs on Kyurem, but I think Specs might edge out as better for this team. Hard hitting already as a special attacker, Choice Specs allows you to muscle past balanced teams and remove some of Ice’s threats to make room for Cloyster and Chien-Pao to close games.
