Living End

Suspend 3-[2][B][B] (Rather than cast this card from your hand, pay [2][B][B] and exile it with three time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, cast it without paying its mana cost.)

Each player exiles all creature cards from his/her graveyard, then sacrifices all creatures he/she controls, then puts all cards he/she exiled this way onto the battlefield.
