Beyond The Permafrost

Permanents don't untap during their
controller's untap phase.
{2}{b}{r}: Untap up to {x} target permanents
where {x} is the number of cards in your
graveyard.
{b}{r}: Untap target creature. Destroy it at the
end of this turn. You lose {x} lives where {x}
is the converted mana cost of the creature.
None so cold. Frozen soul. Subzero.
