Fauniana, the Friendly Helper

If a spell with Gift would be put into your graveyard from anywhere, you may put it into its owner's library fourth from the top.
Whenever you promise a gift to an opponent,
they may gift you the gift back. If they do,
choose one-
•You and gifted opponent each draw a card.
•You and gifted opponent each gain 3 life.
•You and gifted opponent each create a 4/2
green Beast creature token.
