my aforementioned mono Ice team: https://pokepast.es/61fe374d80952c93
it wins against Fire and Fighting a lot/most of the time but will basically never win against Steel. Rock is a toss-up.
walling with pure Ice types and being dealt, like, 20% by a supereffective Z-move will honestly never not be funny to me
if there’s any Pokémon i *might* replace on it, it’d be Froslass; she does have pretty serious difficulties living, and she isn’t usually the lead. or at least turn her into a Destiny Bond trap. still though, she’s my favorite Pokémon, so i try hard to keep her on there, and she *does* do good work against Fighting teams.
