Skarmory has amazing resistances and Roost to play with. He can handle a lot of threats in the game, such as Scarf Medicham/Heracross. He's different from Cresselia. Cress, while being one of the hardest walls to take down these days, doesn't do what Skarmory can do: Spike, have a reliable 50% recovery move, and get trapped by Magnezone. Skarmory's handy resistances make it the perfect counter for things like Staraptor who Cresselia won't counter btw.
