Can you add descriptions and pictures to this RMT please? It would make it look better, and we would know what you want to acheive with each Pokemon.
Anyway, a few quick thoughts:
Unless I'm mistaken, for Bouffalant, Earthquake, Megahorn, and some other moves are all better than Iron Head.
Generally speaking, boosting-type sets with only one move (like Uxie and Cofagrigus) usually don't work well because of the lack of move coverage. I would change a move or two on each of them to make them work better.
For Magneton, replace Light Screen with Volt Switch. Generally speaking, Magneton has an Evolite and a good steel typing, so it can take many hits (even some special hits) well. Also, Volt switch is usually more useful than Light Screen
For Honchkrow, the moves Pursuit and Night Slash are both more useful than Featherdance.
