Espathra/Archaludon Baton Pass Rain

Synergy

Espathra uses Speed Boost and Calm Mind to accumulate stat boosts, then Baton Passes them to Archaludon, making it nearly impossible to KO while it fires rain-boosted Electro Shots. Mega Scovillain redirects attacks away from Espathra with Rage Powder and spreads burns via Overheat, protecting the setup. Politoed sets rain for Archaludon's Electro Shot and deals independent damage with Mystic Water Weather Ball. Sneasler provides Fake Out support to buy turns for Espathra, and Mega Dragonite serves as an alternate mega that covers Charizard matchups where Scovillain is weak.

Win Conditions

Baton Pass multiple Calm Mind and Speed Boost boosts from Espathra to Archaludon, then sweep with Electro Shot under rain. Secondary mode: Polytoad plus Archaludon rain offense without Baton Pass; Mega Dragonite into Charizard matchups.

Lead Options

Mega Scovillain + Espathra, Sneasler + Espathra, Politoed + Archaludon

Threats

Well-played Mega Charizard Y teams that conserve weather. Special damage reduction tools like Snarl, Light Screen, and Parting Shot from Incineroar that strip Espathra's special attack boosts before they are passed. Tailwind teams that can outpace Archaludon even at plus two or plus three speed.
