Aeon's End Engine

Flash, Indestructible
{c} {c}, {t}: End the current turn. If the turn is
ended this way, skip your next turn, then you
may put a card from your hand onto the
battlefield at the beginning of the next turn.
In the twisted corridors of Phyrexia, time itself
bends to the will of the Machine Orthodoxy. Each
tick of this unholy device echoes the death knell
of hope.
