Togekiss doesn't need a fairy type move IMO, with that ability; Air Slash+Aura Sphere and/or Flamethrower should be enough; and since it has access to supportive and set up moves such as Roost, NastyPlot, Thunder Wave, Heal Bell, etc. I don''t think a fairy type move such as Moonblast would be better. Is kinda like having Air Slash on a Charizard Mega Y.
