Anima Forrest Seafarer

If you cast Anima Forrest Seafarer from the
hand, you may draw a card then put a land from
your hand onto the battlefield.
{u}, Return Anima Forrest Seafarer to its owner's
hand: basic lands you control become 5/5 spirit
creatures with flying, haste and indestructible
until the end of the turn. They're still lands.
"This spirit's presence brings peace and creates life.
Those who see it have eternal happiness."
