The Enmity of Eden

Whenever a creature you control attacks, it deals
1 damage to target creature the defending player controls.
Whenever a creature that defending
player controls attacks you, it deals 1 damage to
target creature you control.
And I will put enmity between you and the woman,
and between your seed and her seed. He will crush
your head, and you will strike his heel. Genesis 3:15.
