I've seen some Tornadus/ Terrakion / groudon decks. They are quite the "annoying" deck, as they can tank, and also revenge, and also T1 60... the only thing they need to have in hand is a switch... or if they run a darkrai with prisms as you can catcher up one of the EXP'ed terrakions for "easy" KO... ofcourse you need something which hits for 130.
