Name of the Pokemon: Kubfu (Is Eviolite compatible)
Role(s): Hazard Remover, Hazard Removal Deterrent, Offensive Pivot, Setup Sweeper
Type: Fighting/Poison
Abilities: Defiant /
Inner Focus
Stat Distribution: 50 / 110 / 80 / 70 / 80 / 80 (470 BST)
Movepool Additions: Court Change, Poison Jab, Toxic, Taunt, Poison Fang, Knock Off, Bullet Punch, Fake Out, Slack Off, Burning Jealousy, Venom Drench, Stone Edge, Rock Slide
Movepool Removals: N/A
Justification: Court Change is one of the coolest moves in the game, but it's stuck on something broken in vanilla. So, here's Kubfu to fix that. Kubfu can pretty easily come in on hazards thanks to its pretty good 50/80/80 bulk when holding the Eviolite and access to recovery to Slack Off. Plus, thanks to its Fighting/Poison-typing and Defiant, the only hazard it really cares about is Spikes, as Webs give it a free Attack boost, it resists Rocks, and absorbs Toxic Spikes. Defiant is also cool because, whenever it switches up the hazards, the opponent now has pressure put on them to remove it, as Defog gets abused by Defiant and opposing Kubfu's can get Taunted. Also, there's the hyper-niche option of punishing Rapid Spin with Burning Jealousy, which is funny
Name of the Pokemon: Leavanny
Role(s): Hazard Setter, Physical Wall, Cleric
Type: Grass
Abilities: Grass Pelt / Overcoat /
Grassy Surge
Stat Distribution: 82 / 70 / 112 / 88 / 85 / 67 (514 BST)
Movepool Additions: Toxic Spikes, Spikes, Shadow Ball, Grassy Terrain, Leech Seed, Aromatherapy, Psyshock, Taunt, Body Press, Tailwind
Movepool Removals: Swords Dance, Calm Mind
Justification: To counteract Kubfu's hazard setting ability, we have a bulky hazard setter in Leavanny. Kubfu exists to foil Leavanny's plans of setting hazards, with its super effective STAB Poison Jabs, Taunts, and Court Changes, but that's not to say that Leavanny doesn't have a couple tricks up its sleeve to get its hazards up. Leavanny's massive 82/112 bulk and Grassy Surge's passive recovery mean that it's only 3HKO'd by Kubfu's Poison Jab. Conversely, Psyshock cleanly 2HKOs Kubfu unless it invests a ton in bulk. So, when played right, Leavanny does still have a chance to 1v1 Kubfu, but it'll take a lot of damage in the process. Meanwhile, Kubfu can avoid getting 2HKOed 74% of the time by Bulking Up, meaning that Leavanny will lose unless it predicted Kubfu coming in and Psyshocked instead of setting a hazard. It can also Taunt Kubfu to prevent it from Court Changing, forcing it to kill Leavanny before removing hazards, taking a ton from Psyshock in the process, or use Kubfu coming in as an opportunity to switch to its future teammates. Also, did you know that Tailwind can be Court Changed? Keep that in mind if you decide run Tailwind for some reason
Outside of the interesting Kubfu matchup, Leavanny in general is a flexible wall that can set Spikes, TSpikes, or Webs, brings support for Ground-weak teammates with Grassy Surge, and be a cleric with Aromatherapy.
