Gardevoir

Gardevoir is a solid Trick Room setter and attacker due to its high Special Defense with a strong Pixilate-boosted Hyper Voice. Gardevoir is also one of a few Trick Room setters to have a good matchup against Amoonguss, a big problem for most Trick Room teams. However, Mega Gardevoir's somewhat high base Speed can be an issue after setting up Trick Room, as it ends up being slower than a lot of Pokemon like Tapu Bulu. It also is not quite fast enough to keep up with some of the metagame's bigger threats like Mega Metagross and Tapu Koko outside of Trick Room. Gardevoir's low Defense also means it struggles to set up Trick Room at times and requires Intimidate support to function at its best. Both of Gardevoir's STAB attacks are walled by Steel-types too, one of the more popular defensive types, and so it can find itself unable to deal much damage at times.
