Chaos Moon

A coin-flip that never settles, recalculated every upkeep against a board state both players are constantly altering. The parity check (count all permanents, then read odd or even) makes this one of the earliest enchantments to turn the entire battlefield into a single variable, and it hands you the strangest knob in the game: you tune the spell not by choosing targets but by changing how many things exist. Cast a token, sacrifice a land, let a creature die in combat, and you have flipped the moon's verdict. The upside is a board-wide anthem on red creatures plus a Mountain mana doubler; the downside is your own red creatures shrinking and your Mountains stripped to colorless. Because the count runs at the start of every upkeep, the effect resets before your turn and before each opponent's, so the same enchantment can be a threat one turn and a liability the next without anyone touching it. What keeps the card honest is its refusal to be a static tool: it asks you to manipulate permanent parity as a resource, a far weirder demand than any straightforward anthem or mana rock. Ice Age ran several experiments with symmetry the controller had to actively break in order to profit, but few externalized the math this completely. The permanent total is the dial, and anyone who adds or removes a permanent is turning it.
