Enduring sentinel

You and creatures you control have hexproof. As long as Enduring sentinel is on the top of your graveyard, you have hexproof.
Decree - If Enduring sentinel would leave the battlefield, Enduring sentinel's static abilities last until the end of your next turn.
"They have kept the valley safe from the Spawns for ages. In death, they still will, but for how long ? "
