Chains of Custody2W
Enchantment - Aura (Common)
Enchant creature you control
When Chains of Custody enters the battlefield, exile target nonland permanent an opponent controls until Chains of Custody leaves the battlefield.
Enchanted creature has ward 2. (Whenever it becomes the target of a spell or ability an opponent controls, counter it unless that player pays 2.)
The next pack is the enchantress-focused Constellation pack. Most of the Auras in these decks are meant to be removal, so it's a good thing Sage's Reverie was picked as the go-tall Aura here.
