Tapu Fini

Tapu Fini has a fantastic typing offensively and defensively, with its Fairy-typing giving it a big selling point over other Water-types, giving it a Dragon-type immunity and a Fighting-type resist. While Misty Terrain isn't as game defining as the other Terrains, preventing status and weakening Dragon-type attacks is still very useful overall, especially on something as bulky as Tapu Fini. Tapu Fini's bulk and typing also makes it one of the best Blaziken answers in the metagame. However, Tapu Fini's offensive stats aren't that great, and it can have trouble competing with Suicune due to worse bulk.

Below are some sample sets. These sets are likely to be standard, but they will be expanded upon and updated as the metagame progresses.
