>Grass
Make it resist Fairy
>Rock
Fine they way it is, but since we're cucking fairy, make a Rock/Steel 3-Evolution line with good speed, good coverage moves, high attack, and a decent mid stage on par with Haunter or Machoke, that way it can fuck up both lower and upper tiers and rape fairies all over the place.
>Ice
Make it resist Ground and Dragon. Since we're also cucking fairies, add a new Ice move called Fimbulvetr that does extra damage to Fairies, kinda like Freeze Dry. Give it to a few nice Ice types that could use a movel ike that, such as Kyurem, Jynx, Glaceon, and Cryogonal. Also, make a new ice type, a fast special attacker with more than 100 of SA and Speed. We need more fast ice beam user and less shitty avalugg-style walls.
