This engine relies on your ability to bounce and replay your own defenders to generate infinite green mana and trigger effects. By using the green mana produced by Overgrown Battlement's tap ability, you can pay for Temur Sabertooth's activation to return that same Battlement safely back to your hand. Once the defender is recast, you simply repeat the loop to scale your storm count and create endless entry and leave-the-battlefield triggers. Meanwhile, Akroma's Memorial sits quietly on the battlefield, granting your entire team a massive suite of keywords like flying, haste, and protection to ensure your looping army is entirely untouchable while you assemble the win.
