Indeed, the omni-stat boosts of Ominous Wind, Ancientpower and Silver Wind do come into play quite often. Technician Scyther is also notorious for it's boosted Wing Attack, which it gets STAB on, so that's always a good choice for it's moveset. Togekiss is a very fun Pokemon to use, with attacks like Aura Sphere and Air Slash, I reccomend you find a Shiny Stone and evolve your Togetic :D. The ability Serene Grace is extremely underrated until you actually experience it, on both ends of the spectrum, that is. Iron Head using Jirachi and Air Slash using Togekiss and Shaymin-S have the ability to abuse Serene Grace to the point where your Pokemon can't get an attack in.
