I started playing pokemon early into sun and moon but I always loved the XY cards and had tons lying around the house so this is my first attempt at an XY format deck.
Camerupt may not be my favourite pokemon but its card will always be near and dear to my heart so what better card to base my deck around. (there are lots actually)
As long as you hit 3 energies off of Camerupt you can knock out anything you desire and basic camerupt packs a punch as well and can take out Giratina. (Adding some Burning energies is probably a good idea) And after you have milled most energies and thinned the deck down a bit you can use recycler and super rod to put the energies back in the deck to get a way higher chance to get a OHKO. This deck isn't too expensive so if you're looking for an XY format deck to play casually with friends then why not give it a try!
