This delightful loop turns the humble Kor Skyfisher into a self-returning engine by utilizing Oltec Matterweaver's triggered ability to duplicate your existing artifact tokens whenever a creature is cast. Because Parallel Lives doubles any tokens created into pairs, casting Kor Skyfisher yields two artifact token copies—such as Treasures or Golds—which you can immediately crack for the mana needed to recast it. The Skyfisher's own entry trigger simply bounces itself back to your hand, keeping the cycle seamless while feeding a massive storm count and generating an army of enters- and leaves-the-battlefield triggers.
