>>51461202Regirock. I was playing a prerelease Tournament, think it was Crimson Invasion. There was one guy who had a deck that was 1 Guzzlord-GX and 39 Darkness energy. Because he mulligans so much I was able to draw half my deck, power up Regirock enough to survive and finish it off in two rounds thanks to the special energy in that set. The dude got so much shit for losing
