Infernal sacrifice

As an additional cost to cast this spell, sacrifice a creature.
Add {r}{r}{r}{r}{r}{r}{r}{r} to your mana pool and
you may search your library for a dragon card,
reveal it, put it in your hand and shuffle your
library. This mana stays in your pool as the
phases resolve. Exile infernal sacrifice.
