The Unshadow

When The Unshadow enters the battlefield,
create an Animus token (It's an artifact
with "{t}: Sacrifice this artifact. Put a +1/-1
counter on target creature you control, then
have that creature deal damage equal to its
power to any target."). The Unshadow's power
and toughness are equal to the amount of
Animus tokens you control. Creatures you
control have "{t}{p/b}: Create an Animus token."
{ut}: Sacrifice an Animus token and lose 1 life
