What really interested me was NP Mismagius, Heal Bell Vappy, and Hydro Pump Palkia. I don't play UU but NP Missy seems devastating now that it can set up in 1 turn. Heal Bell Vap seems like it will fit into the standard set pretty well, maybe something like Wish, Surf, Heal Bell, Protect/Ice Beam depending on if you want a gaurenteed Wish heal or a way to deal with Mence. Hydro Pump seems like it will wreck Ubers, maybe getting some OHKO's that Surf didn't get in the Rain.
Extremespeed DNite seems like a mixed bag to me, on 1 hand, he beats Scarfers trying to revenge kill him, but on the other hand I don't really see much else use for it unless I'm missing something. It seems like a secondary option to me.
