Rotomwash

In its own words

Garchomp likely EQ threat vs Gholdengo. Rotom-Wash levitates and can burn it, pivots safely. Preserve Gholdengo.
Shortest explanation on record.
Plan: +2 Garchomp vs 3% Scarf Rotom locked Hydro Pump. EQ is useless vs Levitate, so Dragon Claw is only move that KOs Rotom if it stays. If they switch to Gholdengo to resist Dragon, EQ would be better but Dragon still chips; staying with Rotom and using EQ would leave them alive to hit us. Dragon Claw is safest to secure KO and keep +2 pressure. Don't Mega to keep Speed advantage.
Longest explanation on record.

draft 1 of 3six picked on attempt 1sets legal on attempt 1

"Building around Gholdengo/Kingambit endgame with Dragonite/Garchomp as Dragon-type setup sweepers, Rotom-Wash as defensive pivot, and Volcarona as special Quiver Dance wincon. Gholdengo and Volcarona provide Nasty Plot/Quiver Dance special pressure while Kingambit/Dragonite/Garchomp offer physical Swords Dance/Dragon Dance sweeping with priority. Rotom-Wash gives Volt Switch momentum and Will-O-Wisp support to enable the sweepers."

draft 3 of 3six picked on attempt 1sets legal on attempt 1

"Building for 3v3 BSS pick-3, I need self-sufficient sweepers and pivots.
