Like A dude said, I think Support Tornadus would be a good addition.
Another suggestion is that you replace
Ambipom with
Hitmontop.
Hitmontop is far better at abusing priority than Ambipom, plus he can spin. I suggest a mix between smogon's Rapid Spin and TechniTop sets.
Set
Hitmontop @ Fight Gem / Life Orb
Intimidate
252 HP / 252 Atk / 4 Spe
Adamant [+Atk -SpA]
- Fake Out
- Mach Punch
- Rapid Spin / Close Combat / Sucker Punch / Bullet Punch
- Rapid Spin / Close Combat / Sucker Punch / Bullet Punch
This is a set I used on an old OU sun team I had, and it was great. Fake Out guarantees damage and breaks sashes, and a boosted Mach Punch wrecks anything that doesn't resist it. The last 2 moves are sort of filler, Rapid Spin is what you should go for, but if entry hazards don't trouble you, you can go for something else. Close Combat is a reliable STAB that is crazy powerful with a Fight Gem, Sucker Punch helps nail ghosts trying to spinblock, and Bullet Punch is another reliable priority move that can hit ghosts. There are tons of other moves Hitmontop can use, such as Stone Edge, Toxic, Foresight, Aerial Ace, Low Sweep, High Jump Kick, Revenge, or even Triple Kick. You can also opt for a Life Orb if you don't care about recoil and want consistent power for all of you attacks. In the end, it's all up to you how you use it, you can look up the smogon article if you want more info.
