Delve into the Wilds

At the beginning of your upkeep put the top two
cards of your graveyard into your library.
Whenever a creature card enters your graveyard
from anywhere you gain 3 life.
Sacrifice Delve into the Wilds: Return all lands
from your graveyard to the battlefield tapped.
With eager anticipation the Enclave began to explore
the jungles. Their hunt had finally begun.
