Break the Silence

Split second (As long as this spell is on the stack, players can't cast spells or activate abilities that aren't mana abilities.)
Whenever a player casts a spell, sacrifice Break the Silence. If you do, each creature that player controls gains Calamity 3 (At the beginning of your upkeep, put three doom counters on this permanent. At the beginning of your end step, sacrifice it if it has three or more doom counters on it).
