This explosive loop turns Garth One-Eye into an engine for infinite mana, tokens, and spellcasting by continually multiplying its presence on the battlefield. Spark Double is essential because its nonlegendary clause allows you to stack multiple copies of Garth without the legend rule getting in the way, while Parallel Lives doubles the yield of every token created. By using Twinflame to copy these nonlegendary Garths and feeding the loop with Black Lotus and Regrowth, you can endlessly recur your spells to generate infinite colored mana and infinite card draw on the spot.
