Been working on this decklist for awhile waiting to see what XLN brought us. While the deck feels like a throwback to the AER block, we did gain a few toys that help shore up the build, namely a black draw spell in Costly Plunder that costs 1B instead of a 2BAltar's Reap. Raiders' Wake makes Herald of Anguish's discard ability more potent, along with other discard spells. The deck is designed to not only make our opponents discard and lose life, but also punish them for cycling cards. Our secondary win con is Marionette Master sacking artifacts as we see fit to deal the finishing blow.
