I see, the it might be best to lead with with Simipour and Drapion. Mainly since Simipour resist Tentecruel water moves and can potentially deal with Nidoqueen, while Drapion is overall bulky so should be able to take some hits and fire back as well. Since Aya does have a Venusaur now, probably keep either Pyroar or Unfezant and switch the other for for either Ampharos or Muk.

IIRC Aya leads with Muk and Tentacruel, so I would probably lead with Donphan and Unfezant. assuming your Unfezant can outspeed the Tentacruel. If it can try going for Air Slash on the Tentacruel and having Donphan use EQ. The best situation would be that Tentacruel flinches in which case you minimize the amount of damage you take in the opening turn, while potentially OHKO her leads. If all works out, you theoretically have an answer to most of her Pokemon, just watch out for the Sludge Waves and Spike/Toxic Spikes. On the case that Unfezant does not outspeed her Tentacruel, might be best to
