Well, what are you looking for?
MT has the famous Magmortar Lv.X, Blissey, Feraligatr, and Typhlosion
SW has the hated Gardevoir, Gardevoir Lv.X, Gallade, Banette and Magmortar.
GE has the wonderful Pachirisu and Claydol, along with Magmortar's new partner, Blaziken.
Whatever you want to build. I've named some of the better cards in each set, but there are some other good cards. So yeah.
