Lilith, Daughter of Hatred

All creatures you control are demons in addition
to their other types. All demon creature types
receive +1/+1
Succumb to sin: {b/r}{b/r}{b/r}, Attacking or defending creature opponent controls deals
damage to itself equal to its power. If that
creature would be put into a grave yard, create
a 2/2 demon token creature.
(The daughter of Mephisto, prime evil demon of
hatred, finally returned to sanctuary.
Now the lands will run red with blood...)
