Right, so:

Moon: Lanturn's Signal Beam at Gardenoir, Fathom to use Helping Hand on Impact.

Rachel: Leave combat to use two rage rockets on Impact. Leaves combat, so hopefully immune to damage.

Impact: Dark ambition, leaving him with 0 Rage. Use second adrenaline boost. Attack Frossqueen with Flamethrower. STAB super-effective. Request Swarm Bow in exchange for Flamethrower.

Charlotte: Spitz' Super Fang on Pegidash, Hammond to use Stone Edge on Pegidash.

Renny: Use Serene blessing (Charlotte's enforcer and Milsha to spend 35 rage to extend protection to Matt and Impact). Mollesk to use Rock Slide on Frossqueen, Swampert to Mimic Stone Edge on Frossqueen. We can test flinching another time.

Pierce: Tyranitar with Stone Edge on Pegidash, Blaziken with Overheat on Frosqueen.

Matt: Venomoth form, use sleep powder on Regina

Harliette: Mineral shot on Pegidash, Blissey's sing, also on Regina, deploy Illumise, Bug Buzz on Gardenoir.

Wilhelmina: Nether Shot on Frossqueen.

Trainer Attacks at Pegidash. If it's dead, target Frossqueen.

Gardenoir: Two quad-effective attacks.
Regina: Sleep Powder and Sing.
Frossqueen: Five super-effective attacks.
Pegidash: Super Fang, three quad-effective attacks. Charlotte's and Pierce's Trainer Attacks.

Threw in Fathom using Helping Hand on Impact.
