>>18772959noice set brudda, living heat wave is definitely good - but you get iced by solarbeam by even timid charizard.
252 SpA Mega Charizard Y Solar Beam vs. 116 HP / 92 SpD Mamoswine: 208-246 (104 - 123%) -- guaranteed OHKO
Unfortunately, you need a spread of 144 HP and 252 special defense with a spD neutral nature to live timid charizard's solarbeam. It's a matchup where mamo should just switch out of unfortunately :/
However, you've intrigued me of the potential of an assault vest set. If I can find a working spread I'll definitely post it here
