This set is good with Perish Song Lapras in Doubles:
Sandaconda-Gmax @ Binding Band
Ability: Sand Spit
EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature
- High Horsepower
- Glare
- Rock Slide
- Coil / Protect
I'm still deciding on Coil or Protect, so I'll change it once I've made that decision. But for now, pair it with this:
Lapras @ Leftovers
Ability: Water Absorb
EVs: 252 HP / 4 SpA / 252 SpD
Calm Nature
IVs: 0 Atk
- Freeze-Dry
- Perish Song
- Protect
- Brine
Go for the Perish Song with Lapras, and then use G-Max Sandblast to lock the target(s) in so they can't switch out. Make sure your slower than your opponent or Switch out, or else you'll die first, leaving your opponent with the W.
