Hogswatch

Play at any time a creature is sent to the
graveyard.
Put a Replacement Token into play with the
same abilities as the creature that was just sent to
the graveyard, plus Vanishing 2 and Haste. If this creature deals damage equal to its toughness
before the final Vanishing token is removed,
return the original creature to the battlefield
under your control and exile Hogswatch.
