This ingenious loop relies on casting Broodguard Elite for zero mana via its warp cost, causing it to instantly perish from having zero toughness the moment it enters the battlefield. Pitiless Plunderer watches from the sidelines to turn this continuous death toll into a steady stream of Treasure tokens, which you can sacrifice to generate the green mana needed to repeat the process. Meanwhile, Enduring Renewal swoops in to catch Broodguard Elite on its way to the graveyard and immediately returns it to your hand, bypassing the need to pay regular casting costs and keeping the cycle endlessly spinning.
