Unless Dragon is no longer resisting Grass (please oh please GF, please), it has to be either Water/Dark or Water/Fight.

>DragonDragon Pulse, Draco Meteor, Dragon Tail, Outrage
>PoisonSludge Bomb, Venoshock, Toxic Spikes, Gunk Shot
>Coverageit wants Scald for a defensive mon, even without STAB; guaranteed gets Surf, Hydro Pump, Thunderbolt, (Flamethrower?)
Unless it has a radically different secondary ability (not even Swift Swim is enough), it won't be a fully offensive Pokemon. Its lack of high offensive base stat means a full attacking set will only work ingame.
Thunderbolt/Water moves would only be used, off the top of my head, to hit Steels, who resist/immune to both its STABs.
