Bond of Gifts and Gratitude

When Bond of Gifts and Gratitude enters the battlefield, create a 0/3 green and blue Human creature token with defender and a 1/6 green and
blue Turtle creature token with defender.
Whenever a creature you control that's both green and blue blocks one or more creatures, you may draw a card. If you don't, you may put a land card from your hand onto the battlefield tapped.
