I used DougJustDoug's statistics to work out how many Pokemon are used in 75% of teams. Note that this is different from 'used in 75% of battles'. The problem is that Doug counted not just the Pokemon that appear in a battle, but all the Pokemon that feature in a team, even if some of them end up not being used in a battle. So if a team had Metagross and it ended up not being used in a battle at all, Colin's usages list would not have counted it as a usage, whereas Doug did. Anyway, this is what I found: 75% of OU teams select their 6 Pokemon from 42 Pokemon: Code: Azelf Blissey Breloom Bronzong Celebi Cresselia Deoxys-S Dragonite Dusknoir Electivire Forretress Gallade Garchomp Gengar Gliscor Gyarados Heatran Heracross Hippowdon Infernape Jirachi Jolteon Lucario Machamp Magnezone Mamoswine Metagross Salamence Scizor Skarmory Snorlax Spiritomb Starmie Suicune Swampert Tentacruel Togekiss Tyranitar Vaporeon Weavile Yanmega Zapdos 75% of UU teams select their 6 Pokemon from 39 Pokemon: Code: Absol Altaria Blastoise Claydol Clefable Drapion Drifblim Froslass Gastrodon Glaceon Grumpig Hitmonchan Hitmonlee Hitmontop Hypno Kabutops Kangaskhan Lanturn Lapras Leafeon Manectric Meganium Nidoking Nidoqueen Ninetales Omastar Persian Poliwrath Primeape Probopass Rapidash Rotom Scyther Sharpedo Steelix Swellow Toxicroak Venomoth Vileplume 75% of Uber teams select their 6 Pokemon from 15 Pokemon: Code: Blissey Darkrai Deoxys-A Dialga Giratina Groudon Jirachi Kyogre Latias Latios Lugia Mew Mewtwo Palkia Rayquaza That means that UU as it is now is even more centralising than OU!
