I played a pheonix deck recently with a janky deck recently. Smallpox on turn two won the first game. Small pox on turn two and again on turn four made the game last forever, despite me never once playing a threat. Pheonix has its weaknesses. A lot of its cards, while synergistic, do nothing but draw more cards. I understand the beauty of that, but it also opens the deck up for disruption since izzet plays very little disruption itself and only bolts.
