This clever loop turns Overgrown Battlement and Temur Sabertooth into a self-sustaining mana engine, provided you control enough defenders to generate more than the two green mana required to bounce and recast the Battlement. Dynaheir, Invoker Adept sits alongside them as a proud tactician, granting both haste so your wall can tap immediately upon re-entering the battlefield and a potential copying effect for other non-mana abilities, though the core of the combo relies purely on the profitable recycling of mana and creature triggers.
