Incremental Harvest

When Incremental Harvest enters the battlefield, search your library for a basic land card or gate
and put it onto the battlefield tapped. Then
create a 1/1 white soldier creature token with
lifelink.
When you cast a spell with convoke, you may
return Incremental Harvest to its owner's hand.
