Bjorn's Failure

As an additional cost to Bjorn's Failure, discard
your hand. You gain 1 life for each card
discarded this way.
Return target creature from your graveyard
to the battlefield. It's a Black Zombie in addition
to its other types and gains haste until end of
turn. Sacrifice it at the next end step.
For the rest of the game, if a card would leave a
graveyard, exile it instead.
