Mystical Space Typhoon: Pretty much mandatory side against any deck that runs or sides into a floodgate card that poopoos on your parade
The sideboard takes advantage of the fact that the desire for colorless lands pushes the deck to have red mana to sideboard Fevered Visions, a card that has really impressed me against control decks, along with Gideon, Ally of Zendikar and a couple of counterspells
Having a lot of creatures on the board is a surefire way of utilizing the power of Craterhoof Behemoth A 5/5 body is already a good thing to have but adds a +X/+X counter to it, and every other creature you control, then you will have a million damage on the board This is a good card to have in ramp decks as well as decks that can cast cards without paying mana costs 8
Having a lot of fun with this
Great work on it, it set the tone and vastness of the ambitious crossover set
