>>22837287I would agree on Reasonabke Territory only except the Ground resistence.
Technically all you'd need is adding Freze Dry to Snorunt, Kyurem, Jynx, Glaceon, Regice.
Icicle Crash, Icicle Spear, Ice Fang, Ice Punch, Ice Shard to Kyurem.
Icicle Spear to Beartic.
If not Earthquake at least Bulldoze and Superpower to Kyurem, Zekrom and Reshiram.
Air Slash to Kyurem.
Refrigerate to Mamoswine (too late for Kyurem with the other Dragons is locked in their lore and move+ability combos).
Flash Cannon or Mirror Shot to Glaceon.
Mirror Coat to Cryogonal.
Icicle Crash to the ones you have listed, Empoleon too.
Powder Snow having its power doubled in Hail.
Analytic to all the Regi Trio as HA.
That's all.
