This clever mana-generation loop turns Axebane Guardian into a self-sustaining engine by capitalizing on its own defender trait. Because Fervor grants your creatures haste, the newly recast Axebane Guardian can be tapped immediately to generate the mana needed to fuel Temur Sabertooth's bounce ability. Temur Sabertooth then whisks the Guardian back to your hand for a cheap cost, allowing you to repeat the cycle as many times as you desire for infinite mana and enter-the-battlefield triggers.
