@xxyzx: I tested that Scarfed Set (Dragon Slayer) and yes, you need Ice Beam to OHKO Chomp. The thing is just a monster when it boils down to OHKO Dragon-types, it's just ridiculous. As long as it isn't Ononokusu or Latios, +1 will never OHKO Dnite, but most cases he will just outspeed and OHKO anyway. And also, thanks for the Chansey tip!
@network: Like Scarf Tar? I didn't use it, only the Scarf Set I posted. But seeing as similar DNite became with TTar, I believe it will work in a similar fashion.
I'm not so sure about the other attacks, but it sounds to me like Brick Break would make an excellent slash in that last slot that I was a little indecisive about. However, I think the standard core of Gale/Thunder/Surf should probably remain unchanged.On a rain attacker, I'd personally use Brick Break, Extremespeed, Hurricane and Surf, with Leftovers, a Rash nature, 4 EVs in Attack, 252 EVs in Special Attack and 252 EVs in Speed. Brick Break is extremely useful for nailing Tyranitar on the switch, as this Pokémon very often likes to come in against such a Dragonite and cancel out the rain, creating a very annoying situation for the Dragonite's trainer in my opinion. Thunder or Draco Meteor over Extremespeed is optional, although I'd personally go with Extremespeed as this move can be very helpful in many situations from my experience.
Also, I cannot really see the point of Ice Beam on the Choice Scarf moveset. Dragonite's Draco Meteor deals more damage to Garchomp than Ice Beam does, and not to mention Garchomp holds Yache Berry over ten times more often than Haban Berry according to statistics.
Surf does more damage to Steel-type Pokémon than Thunder in the rain.
EVs: 252 Spa / 252 Spe / 5 Atk
Oh yeah forgot abou that, my bad.
And how is Roost legal when Stealth rock isn't legal on Damp Swampert?
