Name: Sunflora
New Stats: 95 / 105 / 90 / 135 / 95 / 70
New Typing: Grass/Fire
Movepool Additions: Weather Ball, Dazzling Gleam, Heat Wave, Knock Off
New Abilities: Chlorophyll, Flower Veil, Drought
Justification: Flower Veil makes perfect sense since this is a sunflower Pokemon, Weather Ball and Heat Wave are reliable STAB moves, Dazzling Gleam, Drought, and a Grass/Fire typing fit the "sun" theme, and Knock Off was added in an attempt to improve Sunflora's shallow physical movepool
Niche in OU: Depending on the ability it has, Sunflora can be either a physical setup sweeper that can't have its attack lowered or a sun-based wallbreaker with STAB Weather Ball.
Example Sets
Name: Cacturne
New Stats: 80 / 130 / 80 / 130 / 80 / 90
New Typing: Grass/Dark
Movepool Additions: Knock Off, Pursuit, Toxic Spikes
New Abilities: Sand Rush, Dry Skin, Limber
Justification: Pursuit and Limber are references to its Pokedex entries, Knock Off gives all-out attacking sets a reliable physical Dark-type move (Unless Payback Cacturne is a thing...), Sand Rush is a better sand-based ability than Sand Veil, and Dry Skin because... well... it's a cactus.
Niche in OU: A bulky water check, spike setter, and special attacker for sand teams.
Example Sets
Name: Ludicolo
New Stats: 90 / 100 / 90 / 110 / 100 / 100
New Typing: Water/Grass
Movepool Additions: Belly Drum, Slack Off, Thunderbolt, Aqua Jet
New Abilities: Swift Swim, Sheer Force, Vital Spirit
Justification: Ludicolo doesn't have much to improve on, so most of these changes were added for flavor or lulz. Vital Spirit and Sheer Force are references to its Pokedex entries, Belly Drum allows it to take advantage of its increased attack and diverse physical movepool, and Slack Off gives it reliable recovery.
Niche in OU: A Sheer Force user that doesn't get sniped by every priority move.
Example Sets
Name: Jumpluff
New Stats: 85 / 90 / 105 / 55 / 125 / 130
New Typing: Grass/Flying
Movepool Additions: Spore, Baton Pass, Tailwind, Defog
New Abilities: Chlorophyll, Infiltrator, Unburden
Justification: Unburden is the closest thing we have to a tailwind-starting ability and works well with Jumpluff's Acrobatics sets. Baton Pass allows for safer pivoting, Spore is more reliable than Sleep Powder, and Tailwind and Defog are standard Flying-type support moves.
Niche in OU: A fast pivot with support capabilites
