Goryash, Vengeance Incarnate

Haste, Trample
As an additional cost to cast Goryash, Vengeance
Incarnate, sacrifice a creature and pay half your
life total, rounded up. Goryash's power and
toughness are equal to the amount of life lost this
way.
When Goryach dies, it deals damage equal to it's
power to each opponent and each creature.
