Repeat.
This loop is a masterclass in turning self-discard into a devastating engine, built around the way Surly Badgersaur aggressively rewards you for throwing cards away. By cycling Tranquil Thicket, you trigger the Badgersaur to mint a Treasure while seamlessly feeding Life from the Loam back into your hand via its dredge ability, which replaces your draws with self-mill. Meanwhile, Land's Edge acts as an active discard outlet that not only fuels the engine by binning land cards to continually ping away at your opponents, but also triggers Surly Badgersaur *again* for more Treasure generation. The Treasures effortlessly pay the mana cost to cast Life from the Loam over and over, recurring your discarded lands and Tranquil Thicket so the cycle can repeat indefinitely for near-infinite damage.
