Flower Trick | Grass | 60 BP | 101% Accuracy | 15 PP | Always results in a critical hit; no accuracy check.
Role: Strong speed control option. Extremely effective vs CM Kyogre specifically, as Flower Trick will bypass its boosts. Flower Trick does around 59-69 to max HP Kyogre, and 63-75 to 252/196+ Sp. Def Groudon. Limber allows it to be an effective pivot into Thunder Wave, and its potent STABs are capable of threatening all of the Latis, Mewtwo, and the Kaijus. It can also act as a disabler, with access to moves like Leech Seed, Trick, Taunt, and Thief.
Checks/Counters: It fails to make much progress vs the Steels, the normal blobs (Flower Trick does around 25% to +Sp.Def Snorlax), and Ho-Oh. It has a really bad Hidden Power dilemma, as using HP Fire in the Sun can help it take down the Steels, but it both doesn't help it vs Rain Steels and makes it hard walled by Ho-Oh. While it might be faster than +Spatk Mewtwo and can therefore apply pretty good damage onto it, Mewtwo also threatens it extremely hard with Ice Beam and Fire Blast. Flower Trick only does 43-51 to Mewtwo, so it's not exactly an effective way around CM Mewtwo either. It doesn't have many great entry points either outside of Thunder Wave from Groudon. It is also obviously revenged by Deoxys-Attack and struggles a bit with Rayquaza.

Stats: 85/90/84/90/86/120 | 550 BST
Abilities: Shield Dust / Ice Body
Movepool: Astonish, Attract, Bide, Bite, Blizzard, Block, Body Slam, Charm, Confuse Ray, Crunch, Curse, Disable, Double Team, Double-Edge, Dream Eater, Endure, Facade, Fake Tears, Frustration, Hail, Haze, Headbutt, Helping Hand, Hidden Power, Hyper Beam, Ice Beam, Ice Punch, Icicle Spear, Icy Wind, Imprison, Leer, Light Screen, Mimic, Mud-Slap, Night Shade, Pain Split, Powder Snow, Protect, Psych Up, Psychic, Rain Dance, Reflect, Rest, Return, Rollout, Safeguard, Scary Face, Secret Power, Shadow Ball, Shock Wave, Signal Beam, Sleep Talk, Snatch, Snore, Spikes, Spite, Substitute, Take Down, Taunt, Thunder, Thunder Wave, Thunderbolt, Torment, Toxic, Trick, Water Pulse
Role: Can fulfill a myriad of roles, but it can function as all of a Spiker, Spinblocker, and revenge killer simultaneously. It's a very effective lead as well, much like what Deoxys-Speed is supposed to do, except it actually threatens some damage onto both Mewtwo and Groudon. Removed Destiny Bond to remove a lot of the pressure it would have with the move and potentially cause it to be too high value of a pick. Sing for the same reason. Offensively, it does decent damage to Groudon, the Latis, Lugia, and Mewtwo. Its access to several disabling tools makes it positioned pretty well vs stall teams, as while it may let Blissey in, it can Taunt it to get positive progress.
Checks/Counters: Damage wise, it does very lackluster damage to anything remotely bulky that isn't hit by its STABs, such as Metagross, Snorlax, Kyogre (Thunder does around 37%), and Ho-Oh. Of course, it can turn Pokemon like Snorlax into Spikes, but its average bulk makes it hard for it to both effectively set Spikes and keep them up. Spin Armaldo completely ruins it, both offensively and as a Spiker.
Name: Ribombee
Type: Bug/Grass
Stats: 73/98/60/93/87/124 | 535 BST
Abilities: Shield Dust / Swarm
Movepool: Absorb, Aerial Ace, Agility, Aromatherapy, Attract, Baton Pass, Calm Mind, Charm, Covet, Double Team, Dream Eater, Endure, Facade, Fake Tears, Frustration, Giga Drain, Helping Hand, Hidden Power, Hyper Beam, Imprison, Leech Life, Light Screen, Magical Leaf, Mega Drain, Nature Power, Protect, Psych Up, Pollen Puff*, Psychic, Reflect, Rest, Return, Safeguard, Signal Beam, Silver Wind, Skill Swap, Sleep Talk, Snore, Solar Beam, Stun Spore, Substitute, Sunny Day, Swagger, Sweet Scent, Swift, Synthesis, Take Down, Thief, Toxic, Trick
Pollen Puff | Bug | 90 BP | 100% Accuracy | 10 PP | For 2 turns, the target is prevented from healing.
Role: Good speed control vs the Psychics and Groudon. Fairly strong vs bulkier teams thanks to Pollen Puff as well. Unboosted Pollen Puff is a roll (in your favor) to OHKO Latios, but it has just enough bulk to be able to survive +96 Sp. Atk Kyogre Ice Beam from 100%. The 4x resist to Earthquake allows it to take Groudon hits not terribly, although 0 invest neutral HP Ghost still does around 40% and Rock Slide does around 90%. Aromatherapy is the large selling point of the Pokemon, and it allows it to function as a cleric on more offensive teams, allowing you to take Paralysis or Burn trades. Can viably run a Choice Band set as well, especially with Trick as an option. Theoretically, it can utilize a Swam + Liechi Berry set as well.
Added some extra grass moves to its moveset mostly for flavor (Mega Drain), and Synthesis so it can take maybe 1 attack and then heal up.
Checks/Counters: If the Groudon calcs were not apparent enough, Ribombee is made of toilet paper. Almost every single physical attack does upwards of 70%. Even most special attacks will put a massive dent in it, but thanks to Shield Dust, it can swap into Thunder and avoid getting Paralyzed. The Steels answer it extremely effectively, with even HP Fire Forretress outside of the Sun landing a 2hko on Ribombee. Ho-Oh somewhat has to fear the possibility of Hidden Power Rock, but Ribombee can only choose to either hit Steels with HP Fire or hit Ho-Oh with HP Rock.
