Z-Dragon Dance has a nice perk towards Intimidate users, because it resets the user's stats lowered, and thus you can proceed to set-up to dish out a +1 Atk move out of nowhere.
You can even use a Z-boosted Outrage if you don't need to reset your lowered stats before boosting Dragonite with Dragon Dance.
Ice coverage is really helpful in many situations, even if you have to forget to hit Scizor or Ferrothorn without boosts. Scizor and Ferrothorn are easily answered anyway, because they are quite passive or predictable.
In the last slot I really like Earthquake over Extremespeed, which is good, but not so good due to being unstabbed and Psychic Terrain is a thing this generation.
