MrGatr, Well, it's not so much that it's dead, just that it's evolved. Landorus-EX is so good that there's no reason not to use it in a deck with Fighting Energy, so it takes the place of Terrakion-EX and some of Terrakion's spots as well. 60+ damage on Turn 1 for 1 energy is a lot better than 30 or even 90 damage on Turn 2. And Landorus is still arguably better late-game since it gets Max Potion and can OHKO more things.
