>>48912337>MamoswineDecent, but Thick Fat helps mitigate one of its weaknesses.
>WeavileAnything with that much attack speed and access to stab knock off is a guaranteed OU anyway.
>Galarian DarmanitanOnly broken because of its ability.
>GlastrierBatshit stupid stats and Moxie make it hard to sleep on but the typing alone holds it back.
>VanilluxeUseless.
>CloysterOnly broken because of Shell Smash + Skill Link coupled with lots of multihit moves.
All of those Pokémon bar Vanilluxe are more or less good indeed but not by virtue of being ice-types, in fact in most cases the type is more of an hindrance than anything and the only utility this type provides to those Pokémon is the boost to their own ice attacks.
