Spend only black mana on X.
Consume Spirit deals X damage to any target and you gain X life.

Released on September 4, 2009
The amount of life you gain is equal to the number chosen for X, not the amount of damage Consume Spirit deals (in case some of it is prevented).
If the targeted permanent or player is an illegal target by the time Consume Spirit would resolve, the entire spell doesn’t resolve. You won’t gain any life.
