This clever loop relies on the zero-cost targeting ability of Outrider en-Kor to repeatedly point at Task Force without costing any mana. Each time you redirect damage to Task Force, its triggered ability responds by granting it a massive toughness boost, allowing you to repeat the process to scale that toughness arbitrarily high. Once your defender's stats reach astronomical heights, you finish the sequence by casting Vraska's Stoneglare to destroy Task Force and successfully harvest a colossal amount of life.
