>>44353603This is in the right direction, but you could do better.
>Delete hail>Make snow weather that harms Fire and Dragon types and grants +10% chance to freezeSee, Freeze is such a busted status as is, and playing around RNG is unironically cringe. Remove freeze chance, but give and overall buff to Ice type damage, and reduction to Fire type damage, just like in Pokemon Reborn. Could be nice if it harmed types weak to Ice, rather than just Fire and Dragon, but it might be too much.
>Make Icy TerrainLove it. Icy Surge would be so based.
>Slows down not Ice PokemonI feel like this is a bit too much, but it could be alright depending on the context. HDB, flyers and levitators aren't effected, but that'd have to be the only thing to it otherwise it'd be over-saturated imo.
>Frozen Pokemon do not thaw outAgain, playing around Freeze is super cringe. It's already a strong status as is.
>Protects from burnsYes, but move it to Snowy weather.
What I'd add to that:
Hail's accuracy boost to Blizzard would stay, and also apply to all Ice type moves, so Triple Axel would be more reliable without personal set up. And also, Ice types now get a Defense boost, just like Sandstorm's Sp. Defense boost.
