Adding to what everyone else has said, I would build the entire moveset around "abusing" Serene Grace. I'm sure that I've battled Togetics in Pokemon XD that had movesets including Silver Wind and/or Ancientpower. Tri Attack is also bloody annoying on Togetic, though only available on the one from Pokemon XD.
I'll also point out that Serene Grace should double Air Slash's probability of causing the enemy to flinch.
So when I migrate my Togetic from XD to the DS & evolve it to Togekiss, it'll have the moveset:
1. Tri Attack - NORMAL, special - STAB, 40% chance of Burning, Paralysing or Freezing opponent /
Air Slash - FLYING, special - STAB, 60% chance of making the opponent flinch
2. Ancientpower - ROCK, special - 20% chance of raising all of Togekiss' stats /
Silver Wind - BUG, special - 20% chance of raising all of Togekiss' stats
3. Aura Sphere - FIGHTING, special - never miss & Super Effective against Ice and Rock types
4. Air Slash / Silver Wind if not already used /
Water Pulse - WATER, special - 40% chance of confusing opponent
Shadow Ball - GHOST, special - 40% chance of lowering opponent's Special Defense by 1 stage
I honestly don't see the point of wasting a slot with a status inflicting move when you have such a high probability of an ailment occurring by chance, although I suppose it's harder if you don't have Tri Attack available...
Thanks for posting this topic - I think I'm going to grab me a Togetic & get in on the Togekiss action!
