By weaving together these three pieces, you create a self-sustaining engine fueled by Harabaz Druid's ability to scale its mana production with the number of Allies you control. Concordant Crossroads provides the haste essential for letting Harabaz Druid tap the very moment it re-enters the battlefield, bypassing summoning sickness entirely. From there, Temur Sabertooth steps in to scoop the Druid back to your hand for a modest investment, allowing you to replay it, tap it for a surplus of mana, and repeat the loop indefinitely for infinite colored mana, storm count, and creature triggers.
