This potent spell-loop harnesses **Swarm Intelligence** as your engine, doubling every instant or sorcery you cast to generate compounding value. By casting **Brass's Bounty**, you flood the board with Treasure tokens that feed the mana needed to keep the chain alive. You then target your own *Brass's Bounty* with **Narset's Reversal**, copying it through the enchantment while bouncing the original spell right back to your hand. As the copied *Narset's Reversal* perpetually recasts and returns your spells, you continuously mine the treasures from *Brass's Bounty* for an endless supply of mana and artifacts.
