Tapu Fini

Tapu Fini leverages its great defensive typing and stats to secure a place at the forefront of the Doubles metagame. Though Tapu Fini is the only Island Guardian whose summoned Terrain doesn't boost the power of its attacks, its ability to block status and weaken Dragon-type attacks on grounded targets is still quite useful. With a solid movepool that contains useful attacks and utility moves alike, Tapu Fini has every tool it would need to thrive, save for a recovery move. As a result, Tapu Fini can end up being worn down somewhat easily. Tapu Fini is also a bit weak unless it's accrued a Calm Mind boost or two, but its STAB attacks are super effective on large metagame threats like Zygarde, Landorus-T, and Incineroar, so Tapu Fini fits onto most teams quite easily.
