Dark Fruit

{1}: Attach Dark Fruit to a creature you don't
control. As long as Dark Fruit is attached, that
creature cannot attack. If the attached creature
leaves play, return Dark Fruit to your hand;
if Dark Fruit is destroyed, draw a card.
"Once you taste our rare dark fruit, you won't be able
to stop yourself from eating and eating."
- Prizma, Ep. 60
