>>34795435It's actually pretty good in OU. Its 2 best sets are DD with Kommo-oium Z and Belly Drum Salac. Both sets are some issues but are quite viable.
Z-move set: Dragon Dance, Clanging Scales, Close Combat, Filler (Dragon claw, EQ, Poison Jab).
Salac set: Belly Drum, EQ/Poison Jab, Dragon Claw, Drain Punch.
Both sets have 4mss. The Z-crystal set is easier to setup and give +1 to all stats which you should only use after at least 1 DD.
The Salac set is the stronger of the 2 since it gives +6 attack and +1 speed. But you lose half your health. It's best utilized with a momento/parting shot support.
