This clever loop turns Zirda, the Dawnwaker's cost-reducing presence into an engine of endless value by slashing the activation cost of Emiel the Blessed down to just a single mana. With that discount, you can repeatedly blink Skullport Merchant to trigger its entrance ability, generating a fresh Treasure token every single iteration. That generated Treasure can then be immediately sacrificed for the exact mana needed to pay for Emiel the Blessed's next activation, keeping the cycle going infinitely.
