Interesting set. Have you ever thought of doing a write-up for it?
P.S: I've been using Groudon to great success, especially along side Swords Dance Rayquaza. Groudon usually breaks down the walls like Lugia while Trick Room is set up, then, Rayquaza has an easier time coming in and setting up under Trick Room (set-up again by Dialga or Bronzong).
I really have to thank you. Your Trick Room Dialga/Palkia sets got me so interested in the Uber meta-game that I started doing research on it, and I finally decided to make an Uber team. Two actually, the first being a team centered around Swords Dance Darkrai and Dragon Dance Rayquaza, and the second focused on abusing Trick Room.
In your Dialga set, you mentioned Swords Dance Groudon with Iron Ball and Fling. Think you could shed some light on that set?
I'm reading the Dialga analysis you wrote, and I have a hard time seeing how come Dragon Pulse is an obligitory move on SpecsDialga, and if so, should I use Aura Sphere or a Fire move...also, why use Hatsy when Naive loses less stat points?
