Genesect

Genesect excels as a strong offensive pivot that can gain the upper hand in the positioning game thanks to its STAB U-turn, 120 / 120 offenses, wide variety of powerful coverage moves, and excellent ability in Download. It can immediately threaten a wide swathe of the tier for super effective damage, including Kyurem-B, Rillaboom, and Zygarde, and many teams appreciate it bringing in setup threats or Pokemon with favorable matchups. It is able to become a potent wincon with Shift Gear, completely dismantling teams that lack study counterplay options such as Heatran, Volcanion, Zapdos, and Urshifu-R. It also has the sustainability that other setup sweepers lack thanks to Leech Life. Unfortunately, not only does Genesect have no way to hit most Fire-types, but its effectiveness plummets when momentum isn't on its side, either due to Fake Out or opposing forms of speed control. This counterplay exposes its meager bulk and 4x Fire weakness while impeding its revenge killing. Lastly, once Choice Scarf Genesect is locked into a move, it becomes a lot easier to play around. Genesect appreciates teammates that threaten Fire-types like Volcanion, Urshifu-R, and Zygarde, while it threatens Kyurem-B, Rillaboom, and Landorus in return. Shift Gear Genesect in particular enjoys support from Pokemon with redirection, such as Volcarona, or Fake Out, like Zeraora.
