Black and White for me because I loved that it has a lot of good cards. I also liked that it was just abilities and no pokebodies and poképowers anymore. Also it introduced the Full Art cards which we all love. Anyways it introduced some new things and introduced lots of good cards like Revive, Professor Juniper(BSIF), Shift Gear Klinklang, Emboar(Inferno Fangdango), and Reshiram and Zekrom.
