This elegant loop relies on reducing the activation cost of Emiel the Blessed down to just a single generic mana using Biomancer's Familiar, allowing you to repeatedly blink Skullport Merchant without breaking the bank. Each time Skullport Merchant returns to the battlefield, its enters-the-battlefield ability generates a fresh Treasure token that you can immediately sacrifice to fuel the next activation. Because this continuous cycle triggers whenever Skullport Merchant leaves and enters the battlefield, you can easily leverage these infinite iterations to trigger any number of additional enter-the-battlefield or leave-the-battlefield effects your deck has to offer.
