Vanilluxe / Mega Greninja Snow

Synergy

Vanilluxe leads with Snow Warning to set hail and Aurora Veil, then Choice Scarf lets it outspeed most threats for immediate Blizzard pressure. Mega Greninja pairs as a second Blizzard user via Protean, converting to Ice type for accurate never-miss Blizzards in snow, while Dark Pulse and Low Kick cover Steel and Normal resistances. Incineroar provides Fake Out and Intimidate support to give the fragile core extra turns, and Gengar with Destiny Bond serves as a last-resort answer to bulky threats like Archeludon that the team struggles to OHKO.

Win Conditions

Set snow with Vanilluxe to enable always-accurate Blizzard from both Vanilluxe and Mega Greninja; use Aurora Veil to make the team durable enough to trade; Destiny Bond Gengar as a fail-safe against boosted threats that cannot be cleanly KOed.
