Repeat.
This intricate loop transforms a murky puddle into an engine of boundless energy by using Emry, Lurker of the Loch to repeatedly pull Lotus Petal from the graveyard. Each time you recast the Petal, Displacer Kitten’s avoidance trigger blinks Pestermite, whose own entry ability untaps Emry so the cycle can begin anew. Meanwhile, sacrificing Lotus Petal provides the colored mana needed to sustain the loop while generating an endless cascade of triggers, letting you flood the board and overwhelm your opponents.
