Mega Mane really should have at least B- rank. Its main weakness before was that it had to protect turn one to get the speed boost, but now it doesn't, so it can start being faster right away. It works both with and without the Mega, like Mawile, it can be a good Intimidate VoltTurner with Landorus and has moves to cover its weaknesses, besides hitting like a truck. It's frail, yeah, but it can check and scare so many things that it can be a great glue for any team, specially with Ferrothorn being back to the field.
