Lesser Boon of Knox (29) [Radiant Origins: Pantheon]

As you gain this boon, each opponent banishes a card at random from your memory face down. As long as that card is banished, that opponent may look at it and activate it, ignoring its elemental requirements. You draw a card for each card banished from your memory this way. (Start with the opponent next in turn order. You may still look at your own face down card.)
