Corrode Reality

During each player's upkeep place a decay counter on Corrode Reality. If it has 10 or more decay counters on it, they lose the game.
Each player decreases their maximum hand size
by X, draws X additional cards each draw step,
and X creatures they control must attack each turn if able, where X is the number of decay counters on Corrode Reality.
Even the universe rots. Even time bleeds.
