Each player shuffles their hand and graveyard into their library, then draws seven cards. If it's your turn, end the turn. (Exile all spells and abilities from the stack, including this card. Discard down to your maximum hand size. Damage wears off, and "this turn" and "until end of turn" effects end.)

Day's Undoing (CMM 85, Foil) is a blue sorcery from Commander Masters that resets players' hands and graveyards into their libraries and draws seven cards. When you cast it on your turn, it also ends the turn, exiling the stack and moving the game straight to cleanup. The card is commonly used as a draw-reset tool that can disrupt opponents' stack actions while refilling your hand for a big follow-up turn.
