Arbiter of Secrets

Flying, ward {1}

When Arbiter of Secrets becomes tapped, create a Sin token attached to target creature. (They're enchantments with "Enchanted creature has defender."
and "Prevent all combat damage that could be dealt by
enchanted creature.")

2{u}: Draw a card. Activate only if you control a Sin.

"With eyes that see beyond the veil, it weighs the hearts of
mortals, rendering judgment in silence."
