2. When Jirina enters the battlefield, it and Mana Echoes trigger.
3. Resolve the Jirina trigger, creating a 1/1 Human Soldier creature token for each time you've cast Jirina from the command zone this game.
4. When the Human Soldiers enter the battlefield, Mana Echoes triggers that many times.
5. Resolve the first Mana Echoes trigger, adding C for each Human and Soldier you control.
6. Repeat step 5 for each remaining Mana Echoes trigger created in steps 2 and 4.
7. Activate Umbral Collar Zealot twice by sacrificing Jirina and a Human Soldier.
8. Choose to return Jirina to the command zone from your graveyard.
9. When Jirina and the Human Soldier die, Pitiless Plunderer triggers twice, creating two Treasure tokens.
10. Holding priority, if you control a Human Soldier, activate Umbral Collar Zealot by sacrificing a Human Soldier.
11. If you sacrificed a Human Soldier this way, Pitiless Plunderer triggers, creating a Treasure token.

This loop centers on recasting Jirina Kudro from the command zone to flood the board with Human Soldier tokens, which immediately supercharges Mana Echoes to generate an avalanche of colorless mana. As those tokens and Jirina are sacrificed to Umbral Collar Zealot, Pitiless Plunderer steps in to turn every single death into a valuable Treasure token. With the treasures funding your next commander tax and the engine looping seamlessly, you get an endless supply of death triggers, colored mana, and creature tokens to overwhelm the table.
