Raviel, Warden of Sinners

When Raviel, Warden of Souls enters the battlefield, exile target non-land permanent
you don't control until Raviel leaves the
battlefield.
At the beggining of each opponent's end step,
Raviel deals damage to that player equal to the
amount of permanentes exiled or enchanted by
an enchantment you control.
"Heavier the sin, tightier the chains."
