This cube was played at the Salt Box in Baltimore! One player named Sylvia (the eventual champion of the event) played a deck with both Blood Moon effects, and pointed out that each opponent was able to easily sideboard or change their fetch habits between games to dramatically reduce their value. Also, Moons in constructed were meant to catch opponents by surprise which is harder in a small pod, and there is no Tron or Inkmoth Nexus to punish anyway. Another cut I'll be making is Obstinate Baloth: Black Discard suffers here and doesn't need any additional hosing.
In their place, I want to give a Ponza-like deck a chance with Molten Rain, and Goblin Dark-Dwellers can recur it, or can go in a variety of decks like Nahiri control, Mardu Pyromancer, or Jund. In Baloth's place, Acid-Moss can flesh out a RG Ponza like deck, or get Scapeshift up to the key land number.
In the event, one of the FINALS matches was Death's Shadow/Pyromancer vs a Scapeshift combo deck! This is the most successful I've seen Shadow be, AND the first time I've seen kills with Valakut and it was great to see it work consistently when supported properly (the player was running extra cards to be able to hit the right land numbers mid- and late-game.)
