I apologize for the two n00b questions. Just something that's been on my mind.
1) In ORAS I asked a quick question about the use of stat-drop moves (Screech, Featherdance, etc), and was told that they weren't good moves because they don't help with regaining momentum or forcing switches. I was told that it's always better to boost stats. However, I just saw that one of Dugtrio's top ORAS movesets include Screech. Can somebody explain why it's OK in Dugtrio's case? Are there any other examples of pokemon who can use stat-drop moves effectively? It seems a shame to not use these "interesting" moves...
2) This has bothered me for a long time. I've always had the belief that two-turn moves (i.e., Fly, Bounce) should be avoided at all possible. However, I've seen pokemon as Gyrados use Bounce. I understand that the turn in the air can help with leftovers recovery, but still... why? Wouldn't you lose momentum by allowing your opponent to switch in a favorable counter? if I really needed a flying-type move on a pokemon that absolutely couldn't learn any, I would use Hidden Power.
