Breloom

With an amazing Attack stat, access to Spore to put its opponents to sleep, and an ability in Technician to power up its weaker moves, Breloom can be quite the annoying foe to face as a lead or a late-game sweeper. However, Breloom is pretty frail and slow, making it hard to use without a Focus Sash to protect it from Pokemon that outspeed and OHKO it easily. The newly introduced terrain setters in Tapu Lele, Tapu Koko, and Tapu Fini also mess with Breloom’s usage, as Tapu Lele can prevent Breloom from using Mach Punch on opposing foes and both Tapu Koko and Tapu Fini make grounded Pokemon immune to Spore. It is worth mentioning that none of the Pokemon mentioned earlier can switch into Breloom safely to set up their respective terrains. However, these terrains are still fairly common in the Battle Spot Singles metagame, making Breloom tough to bring into battles.

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