I have been toying around with my Garchomp deck for a while now, and I decided to take out altarias and replace them with 2 big basics and some more trainers:
Strategy: Do early damage/tank with Landorus/Terrakion EX while setting up Garchomp. Energy Switch+Max Potion keep my Pokemon alive while being able to reuse the energy. Terrakion was put in because I didn't have a 2nd Lando EX, but he's nice against Darkrai decks and isn't weak to Keldeo like Lando.
I'm still having a bit of trouble against Keldeo decks and Darkrai decks. Any help would be appreciated
