Description:
This unique hail team was brought by Dragon Claw to a WCoP Finals tiebreaker against TDK. Substitute allows Arctozolt to alleviate pressure in predicting switch-ins, making it easier to utilize its high-power dual STAB combination to break past many common backbones. Its EV spread allows it to KO Kartana and Dragapult with Blizzard after Stealth Rock damage while naturally threatening Buzzwole. Alolan Ninetales is the optimal hail setter, fitted with a good Speed tier and great utility in Encore and Aurora Veil as well as the ability to switch into Weavile in a pinch. Heatran’s Speed investment allows it to outspeed and threaten Choice Specs Magnezone, Bisharp, and Aegislash, which the team otherwise has a very difficult time consistently playing around. Landorus-T covers Heatran's lower Special Defense investment and maximizes its own bulk to take hits from opposing Heatran, Tapu Koko, and Dragapult; moreover, its IVs give it slow U-turns against opposing Landorus-T while still outspeeding Adamant Crawdaunt. Kyurem's natural strength and perfect neutral coverage alongside hail and Aurora Veil helps it force damage quickly and efficiently on Pokemon like Heatran. Its Speed tier is designed to outspeed Modest Tapu Lele and Modest Kyurem. Lastly, Tapu Lele provides immediate pressure on Dragapult and Weavile thanks to Choice Scarf and Psychic Terrain to safeguard Arctozolt and itself from priority options that could threaten key chip damage.
