This elegant loop leverages Dour Port-Mage's activated ability to continuously rescue Possessed Skaab back to your hand, which in turn perpetually recycles Walk the Aeons from your graveyard to secure endless extra turns. Every time you bounce the Skaab, Dour Port-Mage's triggered ability rewards you with a fresh card draw to grease the wheels, turning your recursive engine into a card-advantage machine. Because Possessed Skaab is exiled if it would normally die instead, bouncing it directly to hand bypasses that restriction entirely, keeping the undead horror ready to replay over and over again.
