A game of wits and deception!
Morph and Foretell allow you to play loads of facedown cards to surprise your opponent. Suspend creates interesting tension with by revealing information, which can force you and your opponent to play around it. A sprinkling of ninjutsu, off-color counterspells, and free spells were included to keep players on their toes - your opponent might still have a trick, even if they're tapped out. The cube was then rounded out with cards chosen for their interactions with morph: colorless matters, 2/2 vanilla, 0 CMC, or unorthodox ways of flipping cards up such as flicker.
The cube includes four conspiracies: only cards that significantly alter the way you build your deck were included.
