This loop achieves infinite green mana by leveraging Elvish Archdruid's massive mana-producing tap ability, which scales with your board state, to completely cover the activation cost of Temur Sabertooth. Because Temur Sabertooth bounces the Archdruid back to your hand, you can recast it fresh every time, and thanks to Fires of Yavimaya granting haste to your creatures, the newly cast Archdruid can be tapped for mana immediately without suffering from summoning sickness. As you repeat this cycle, Elvish Archdruid also pumps the team's stats via its static anthem effect, letting you easily generate infinite enters-the-battlefield triggers, leaves-the-battlefield triggers, and storm count.
