Whenever you sacrifice an artifact create a 1/1 black Transylvanian token creature with "This creature
can't block."

{1}{r}, Sacrifice a Transylvanian: Each opponent loses 1 life.
{1}{w}, Sacrifice a Transylvanian: Gain 1 life, Draw a card.
{1}{b}, Sacrifice an Transylvanian: Return target creature card from your graveyard to your hand.
