This looping engine relies on the red mana generation of Ardent Electromancer—assuming your party is three or four strong—to repeatedly cycle itself and Stormfront Riders through Sneak Attack. While Sneak Attack provides the fast, discounted entry and haste for just one red mana, Stormfront Riders acts as the mechanical hinge: its entry ability bounces both itself and the Electromancer right back to your hand, while its triggered passive ability creates a 1/1 white Soldier token every time a creature leaves the battlefield for your hand. Because the mana produced by the Electromancer outweighs the cost to recast them both, you can continuously repeat the cycle to generate an endless storm of Soldiers, entry and exit triggers, and red mana.
