Enchant creature
When enchanted creature dies, you gain X life and draw X cards, where X is its toughness.
Fruit of the First Tree can enchant any creature, but Fruit of the First Tree’s controller will gain life and draw cards.
Use the creature’s toughness when it left the battlefield to determine the value of X. If that number is 0 or less, you won’t gain life or draw cards. (You won’t lose life or discard cards either.)
