I think we're pretty much decided on this one AB:

Harliette: Aquashot, fuck yeah. STAB plus weather bonus (on Wildfire, silly!). Nidoqueen to use focused earthquake, Illumise to use helping hand on its master
Charlotte: Pike to use Thunder, Hammond with Stone edge
Pierce: Aria using Thunder, Kingdra using a water attack on Harliette
Rachel: Rage Rocket on Wilhelmina. Rage Rocket on Rachel.
Renny: Swampert use Surf on Impact and Fanthom for cleaning. Magnezone to use Mimic to mimic a water move on Matt for same reason.
Moon: Deploy Fathom and Starmie, one using a water moves on Impact and the other on Matt.
Wilhelmina: Maid to Mistress, two Dark Shots toward Wildfire.
Matthias: Paradigm shift to Porygon Z, use Hyper Beam (paradigm-shifted pokebrids don't need to recharge, do they? If they do, thunder instead.)
Lexhur: Save up his rage.
Impact: HV rifle. Hopefully gets water and fire armor next turn. Hint hint.
Trainer attacks to hit wildfire as well, if they can.
If a water move to wash off oil is used on an already-clean ally, have that water move redirect to Impact. If Impact's clean, wash off Matt, if Matt's clean, wash off Harliette.
