This delightful little loop turns a simple sacrifice outlet into an engine of endless rebirth, relying entirely on Melira, Sylvok Outcast and her passive immunity to prevent the usual toll of death. When you feed Trapjaw Kelpie to Carrion Feeder, the Kelpie's persist ability would normally brand it with a -1/-1 counter and put an end to its usefulness—but Melira's presence completely nullifies that drawback, allowing the Kelpie to return to the battlefield fresh and unblemished every single time. As the cycle spins endlessly, Carrion Feeder grows to colossal proportions while generating an endless stream of entering, leaving, dying, and sacrificing triggers for whatever sinister payoff you have waiting.
