Sir Haresley, Savior of Easter

Protection from creatures
At the beginning of each player's end step, if no creatures attacked this turn, he or she may create
a green, white and blue artifact token named Easter Egg with "{t}, Sacrifice this artifact: Flip a coin. If it comes up heads, you gain 3 life. Otherwise, create a 1/1 white Chick creature token."
