It's turn 6 of your kitchen-table magic game. Both players have three creatures out. All of them have big butts, and there are no profitable attacks. You're scratching your head, hoping to draw something - anything - to break the board stall.
But what if... every creature died to a single hit?
Mission Statement: Every creature in the cube must have one toughness. No abilities may directly increase a creature's toughness. Any creature tokens created must also have one toughness.
What Follows: When every creature is an X/1, many facets of the game change drastically. Creatures with first strike are almost guaranteed to kill whatever comes in their way. Trample is going to hurt a lot. 1/1 tokens are no longer chump blockers; they are deadly caltrops. Oh, and actual Caltrops? Banned to power. Just like Tim, who now reads ": Destroy target creature."
This cube is built heavily around the combat step.
