Demon Of Promise

When Demon Of Promise enters the battlefield,
create two 3/3 Black Hellhound tokens with
"When this creature attacks, destroy target
creature with a wish counter."
Whenver a creature with a wish counter dies,
search your library for a card or a card from
outside the game and put it into your hand, then shuffle your library.
{b/r}{t}, pay 3 life: Target creature gets a wish
counter.
