This is my favorite D-nite Set
Bulky D-nite
Dragonite @ Leftovers
Ability: Multi Scale
Nature: Impish
Evs: 252 HP / 252 Atk / 6 Def
~ Dragon Claw
~ Earthquake / Fire Punch
~ Thunder Wave
~ Roost
Admittedly, he hates Toxic, Mamoswine, and Skarmory (without Fire Punch), but he is amazing wall with this set. You T-Wave on the first turn and if you lucky they will get parahax, and if your not you can just roost of the damage. Dragon Claw is for a powerful STAB attack. Fire Punch has really good type coverage for his weaknesses, but Earthquake has more power.
