This dazzling loop relies on Emiel the Blessed to continuously exile and return Alena, Kessig Trapper to the battlefield, resetting her ability each time she flickers back in. Because Alena checks the greatest power among creatures that entered the turn, her tap ability produces a growing surge of red mana that easily outpaces Emiel's activation cost once you've generated enough mana to start the engine. Meanwhile, Fires of Yavimaya quietly grants haste so that Alena can tap the very moment she re-enters the battlefield, letting you generate infinite red mana and infinite creature enters-the-battlefield triggers.
