Huntress of the Mortal

Changeling (This card is every creature type.)
Whenever a creature enters the battlefield that
shares a creature type with Huntress of the
Mortal you may pay {1}{r/w}. If you do, destroy
target Human. You gain life equal to its mana
cost.
"The race of humans is fallible and foul. Thankfully
they can be easily deceived."
