The Plan is to use Forest Curse on Volcanion and Sunny Day in the first two turns while Volcanion does some attacks. Then if Trev is still alive use Trick Room, either to utilize it myself or to negate the enemy trick room team. Sudowoodo is also there to potentially gain this benefit of the added Grass Stab to Rock Head Wood Hammer. Togekiss is their to be a nuisance in either flinches or Follow Me moves, and then Incineroar and Marowak are there to simply work alongside Tricanion in their own special ways. Is this strategy good? How can I improve upon this?
