I don't know why roost can't be learn by it or why we have roost now means we won't have a flying type. Please explain?
fire/ice (I personally like the ones that contradict)
After using Roost, the Pokemon loses its Flying type. So it's kinda impossible for them to create a pure flying type. I think they made it default that "pure" flying types must have Normal type as their secondary type.
