His gimmick was a Reverse Field that inverted weaknesses and strengths, effectively more dangerous than a Mountain Field that buffs rocks since the Inversion turns Rock's many weaknesses into resistances. It was a field so bizarre I stopped bothering working on it.
However, using Misty Terrain got rid of it even after it dissipated, so my Prankster Meowstic was a sacrificial pawn. After that Pyukumuku got rid of the Tyrannitar and poisoned the Mega Aerodactyl, then it was all uphill from there as the remaining pokemon were slow, so my Earthquake Krookodile with Moxie sweeped everything.
