"No card is an automatic four of, not even Pox and Smallpox." - the father-thread under Card analysis. If anything, I'd just run Big Pox instead of Smallpox. I should test Curse of the Cabal. It's one hell of a bomb. Assuming you keep Teferi, Time Raveler off the table. Since I'm of the mana denial flavor, they'll probably be in deep trouble since I'm hitting the lands, they'll probably be sacrificing relevant permanents to buy time. I'm trading Nether Void to finish my RUG Delver land sets. Turns out that Winter Orb with Artifact Mana is nastier...:cool:
