Resolve the first Unlucky Cabbage Merchant trigger, causing you to search your library for a basic land card and put it onto the battlefield tapped.
When the land enters, Tireless Provisioner triggers, creating a Food token.
Repeat steps 3 and 4 for the remaining Unlucky Cabbage Merchant trigger.
Repeat from step 1.
This clever loop turns the unassuming Unlucky Cabbage Merchant into an engine that pulls every basic land straight out of your library. By sacrificing the Food tokens provided by the Merchant itself—or generated on demand by Tireless Provisioner's landfall ability—you feed them to Krark-Clan Ironworks to generate the colorless mana needed to fuel Emiel the Blessed's blink ability. Each time Emiel blinks the Merchant, it re-enters to generate another Food, while its sacrifice trigger lets you tutor up a fresh basic land to keep the chain reaction rolling.
