Identifier X= # of opponent's Redeemed Souls
If your hero wins a battle and a Redeemed soul is not put in your land of Redemption you may look at the top X cards of deck, place a card in your hand, and underdeck the rest or you may search opponent's deck or discard pile for a lost soul and begin a Rescue attempt for a lost soul of your choosing in opponent's land of Bondage. Limit once per turn. CBN
That's it for now. Let me know what you think.
