Veil of Despair

Ward {3}

Whenever you draw a card, create a Sin enchantment
token attached to target creature you don't control.
(They’re enchantments with "This creature can't attack"
and "Prevent all damage that would be dealt by
enchanted creature.")

At the beginning of your end step, enchanted player mills
X cards, where X is the number of Sins you control.

"As the tide of sins rises, so do the secrets of the past."
