I wouldn't advise having both Dragon Rush and Dragon Claw together, as two Dragon attacks are pretty pointless together unless one is special.
My suggestion is to remove Dragon Rush with Iron Head for coverage against Fairy types.
No to Iron Head. Earthquake does enough to them already, while Stone Edge handles Togekiss:
-Draco Meteor
-Earthquake
-Stone Edge
-Fire Blast

(note that Sand Force is useless in 1v1 formats without sandstorm, which this set has no room for)
