This dazzling loop hinges on the interplay between Alena, Kessig Trapper and Emiel the Blessed to generate an endless surplus of red mana. Because Fervor grants your team haste, Alena can immediately tap the moment she returns from exile to produce red mana equal to her own power—which remains locked in based on the greatest power among creatures that entered that turn. You then use a portion of that windfall to activate Emiel the Blessed's blink ability, resetting Alena and allowing her to re-enter the battlefield ready to tap for even more mana than the activation cost required.
