I haven't seen anyone talking about how busted hail teams could be this gen. First of all, we finally got a great slush rusher in Arctozolt. Electric/Ice stab is amazing, only rotom-frost had it before. But the icing on the cake has got to be its new move: bolt beak. Physical electric at 85bp, but it doubles if you attack first (Arctozolt moves first under hail most of the time). This is essentially an electric type V-Create, busted as hell. 55 base speed might seem poor, but with slush rush and jolly you still outspeeding everything not scarfed, and even if you're adamant all you miss out on is Dragapult. Arctozolt bout to single-handedly put hail back in the weather war.
Eiscue also looking broken on hail teams too. Unless I'm missing something, its ability makes it immune to almost all physical attacks under hail (only multi attacks like rockblast breaking it). This mon sounds annoying AF, if I'm right you beating almost every physical attacker under hail. I don't know what moves it would run since its support movepool kinda trash. Maybe bellydrum + agility, or some ungodly substitute + whirlpool trapping bs.
Not to mention, Abomasnow and Vanilluxe get auroraveil this gen, so alolan tales isnt the only veil setter now. Hail teams looking like a huge potential threat this gen.
