I'm afraid I won't get to BBRR for Kroxa with Pox effects. It's absolutely backbreaking and all my creatures are resistant to it, so I'd like to run it, but how do you deal with the land loss though.
PS: Graven Cairns is in the deck over Urborg because of the need to generate BB and RR for Hymn, Skelemental and Kroxa in case people were wondering.
I'd trade Davriel for Crucible of Worlds. Just need to get to it slowly as the dual mana base won't like Dark Ritual. Or maybe Mox Diamonds? The discarding wouldn't mean anything after all once the Crucible sticks
Three Lilianas to rule them all. One Pox to find them. Smallpox to bring them all and in the Sinkhole bind them!
