>>23022345>already a mega to piloswineby that logic so is gallade, scizor and steelix. don't be stupid.
and your list is completely backwards. gliscor is a nigger and mamoswine is the antimeta since gen 4. togekiss is actually worse after the powercreep despite its fairy type, and weavile is largely outclassed by greninja, bisharp and various megas, and gets fucked by priority.
mega mamoswine literally cannot go wrong short of reducing its stats. you're right that poison heal is tough to beat, but offensive gliscor is actually quite scary, and there are always custom abilities.
