This ingenious loop revolves around leveraging Drowner of Hope's entry trigger to generate Eldrazi Scion tokens, which are then doubled into an army of four thanks to the explosive token-replacement effect of Mondrak, Glory Dominus. By using three of those freshly minted Scions for mana, you can easily fund the activation cost of Emiel the Blessed to exile and blink Drowner of Hope right back onto the battlefield. Because Emiel the Blessed resets the entire process with mana to spare, you end up with infinite colorless mana alongside an endless swarm of tokens and triggers.
