Modified version of the Infect and Defile Event Deck. I went 3-1 in my first Standard tournament, so I'd appreciate any tips for improving this deck! (I was playing against people using Valakut and Primeval Titan+Hydra-based decks mostly. I usually won the first game easily, lost the second easily, and barely lost the third.)
