Ceaseless Bidding

Mill a card, then return each creature card from
your graveyard to the battlefield. They're black Zombies in addition to their other colors and
types and they gain haste and decayed.
(A creature with decayed can't block. When it attacks,
sacrifice it at end of combat.)
Epic (For the rest of the game, you can't cast spells.
At the beginning of each of your upkeeps, copy this
spell except for its epic ability.)
