Wrenn and Seven

Reveal the top four cards of your library. Put all land cards revealed this way into your hand and the rest into your graveyard.
0: Put any number of land cards from your hand onto the battlefield tapped.
Create a green Treefolk creature token with reach and "This token's power and toughness are each equal to the number of lands you control."
Return all permanent cards from your graveyard to your hand. You get an emblem with "You have no maximum hand size."
