Touch of Moonglove

Oracle Text

Target creature you control gets +1/+0 and gains deathtouch until end of turn. Whenever a creature dealt damage by that creature dies this turn, its controller loses 2 life. (Any amount of damage a creature with deathtouch deals to a creature is enough to destroy it.)

Card Rulings

6/22/2015 The controller of the creature dealt damage by the target creature is the one who loses 2 life, not the controller of the target creature.
