Corpse Concealer

If a creature an opponent controls would die,
you may pay {1}{b}. If you do, exile it instead.
When a creature card is exiled this way,
create a token that's a copy of it, except its an
artifact called Carpet and isn't legendary if it
was legendary. (It's no longer a creature.)
{t}, Sacrifice a Carpet: You draw a card and you
lose 1 life.
