This elegant loop relies on Axebane Guardian generating more mana through its defender-scaling tap ability than it costs to replay it, while Temur Sabertooth facilitates the infinite bouncing and recasting of the Guardian. Meanwhile, The Fire Crystal plays a crucial supporting role by granting your creatures haste so Axebane Guardian can tap the very moment it hits the battlefield, and its cost-reduction ability even shaves mana off your red spells if you choose to expand your turn. By looping this mana-positive bounce engine endlessly, you easily generate infinite enters-the-battlefield and leaves-the-battlefield triggers, boundless colored mana, and an enormous storm count.
