You can use any Pokemon as long as it's not on the banned list (Mewtwo, Mew, Lugia, Ho-oh, Celebi, Kyogre, Groudon, Rayquaza, Jirachi, Deoxys, Dialga, Palkia, Giratina, Darkrai, Shaymin, Arceus, Reshiram, Zekrom, Kyruem, Keldeo, Meloetta, Genesect).Does anybody know which pokemon are "banned" from the battle subway/institute, besides the legendaries? Can you use traded pokemon, or ones from previous gens?
