" —Elesh Norn

When Reveillark leaves the battlefield

if each player has 10 or less life

Moss-covered statues littered the area

"It is in our nature to recognize beauty

and the steel became greaves

But I'm not tired

your opponents and creatures your opponents control with hexproof can be the targets of spells and abilities you control as though they didn't have hexproof

Whenever another artifact enters the battlefield

Draw a card for each creature destroyed this way
