Veil of Purity

Ward {3}

Permanents entering the battlefield don’t cause
abilities of permanents your opponents control to trigger.

Whenever a creature enters the battlefield under an
opponent's control, you may create a Sin token attached to
it. (They're enchantments with "Enchanted creature has
defender." and "Prevent all combat damage that would be
dealt by enchanted creature.")

"Purity binds sin and silence darkness."
