>>21715175>Ferrothorn and SkarmoryMetagross learns Thunderpunch and Hammer arm. TPunch is actually very common on it, as it always fucks up Azumarill, and Hammer Arm lowers your speed, but that's way less important for a Pokemon meant to punch holes in teams.
It has ways around almost any Pokemon, it's issue is that it needs to sacrifice a precious coverage move. It essentially has to choose it's own counters.

Aegislash will need to start running Shadow sneak standard, or it'll stand no chance against a stock M-Meta.
Standard play will be Aegislash soft checking M-Meta by either picking off a weakened one with Shadow Sneak, or tanking the first EQ in Shield form, going for Shadow Ball, and then finishing it off with Shadow Sneak.
Of course it still poses a threat, but it's not as much as a hard check as people thought. Combined with M-Meta's role as a wallbreaker, it's not surefire.
