This verdant loop lets you turn a single mana-dork into an endless wave of green mana, storm count, and creature triggers. The engine hums when you tap Circle of Dreams Druid for a flood of green mana, which easily pays for Temur Sabertooth’s bounce-ability to scoop the Druid right back to your hand. From there, you simply replay the Druid to the battlefield to net a profit of green mana on each iteration, letting you repeat the cycle indefinitely. While Samut, Tyrant Smasher isn't strictly required to make the core loop fire, her passive ability ensures that your recasted Druid—and any other creatures you bring along for the ride—gain haste immediately so you can tap them without missing a beat.
