Hidden Power Dragon counts now k?
Jks anyway, Ampharos gets Dragon Pulse (gets it at 'start' and can be relearnt at level 65 in case you're wondering). Could be more but Bulbapedia only has that one.
Edit: Screw Bulbapedia. In addition to Dragon Pulse, it gets Outrage (move tutor b2w2). Serebii says so :> and showdown has it.
