Elspeth's Shroud

Artifacts, Creatures, Enchantments, and Lands
you control have indestructible
When this card enters the battlefield, if a
creature or planeswalker left the battlefield this
turn, untap all creatures you control.

Once the cloak of a proud Knight of Bant, it now
serves as a reminder of a humble woman who longed
for nothing more than a home.
