K I see a lot of offensive variants but this one has a little more longevity at the cost of some power.
Dragonite @ Yache Berry/Leftovers
Trait: Multiscale
Adamant Nature (+Atk, -SAtk)
EVs: 252 Atk/ 180 HP/ 68 Spd
- Dragon Claw
- Fire Punch
- ExtremeSpeed
- Roost
this set abuses Multiscale to stay alive a long time and pick the perfect moment to launch a counter attack when put on the defense.
Yache Berry or Leftovers is really if you would rather not risk being KO'd by Dragonites only major (x4) weakness to Ice, and Mamoswine, Weavile, and Donphan can all use Ice Shard to stop Roosting to fix a broken Multiscale. Leftovers is for the those who worry less about Focus Sash Weavile landing an Ice Punch, or Starmie packing Ice Beam. Politoed on Rain Teams can also prove troublesome....
Dragon Claw is chosen over Outrage to avoid becoming locked into one attack and becoming and easy target for Ice Sharders.
Fire Punch provides coverage obvious coverage against Ferro and Scizor.
ExtremeSpeed is to help control the momentum and take the offensive back when you see an opportunity. it also protects against a predicted Ice Shard from a 1HP Focus Sashed opponent, hence we see the logic behind Dragon Claw > Outrage.
this is definitely better suited for Stall oriented teams, or teams that need something to provide decent walling ability while still packing plenty of punch.
