Yeah, now long live the Fairy ruled Metagame. I can't wait for Gen 8 when they have to release another new type to satisfy the whining of people claiming Fairy is too unbalanced. Assuming the rumors are true that it is immune to dragon and resists ice.
If the only weaknesses these things have are poison and steel, all we need is one good defensive Fairy and I guarantee you that thing'll be on everyone's team (or a steel/fairy, neutralizing steel damage and making it immune to poison, giving it 4x resistance to Ice and being immune to dragon)
