How it works

1. Activate Warren Soultrader by paying 1 life and sacrificing Reveillark.
2. When Reveillark dies, it triggers, returning Seedship Broodtender and Boss's Chauffeur from your graveyard to the battlefield. Boss's Chauffeur will enter with a +1/+1 counter on it equal to the number of creatures you control.
3. When Seedship Broodtender enters, it, Case of the Uneaten Feast and Boss's Chauffeur trigger.
4. Resolve the Case of the Uneaten Feast trigger, causing you to gain 1 life.
5. Resolve the Boss's Chauffeur trigger, putting a +1/+1 counter on Boss's Chauffeur.

7. Resolve the Warren Soultrader ability, creating a Treasure token.
8. Activate Warren Soultrader by paying 1 life and sacrificing Boss's Chauffeur.
9. When Boss's Chauffeur dies, it triggers, creating a 1/1 Citizen creature token for each +1/+1 counter on it.
10. When the Citizens enter, Case of the Uneaten Feast triggers that many times, causing you to gain that much life.
11. Resolve the Warren Soultrader ability, creating a Treasure token.
12. Activate Warren Soultrader by paying 1 life and sacrificing a Citizen, creating a Treasure token.
13. Repeat step 12 two additional times.
14. Activate five Treasures by tapping and sacrificing them, adding 3.
15. Activate Seedship Broodtender by paying 3 and sacrificing it, returning Reveillark from your graveyard to the battlefield.
16. When Reveillark enters, Case of the Uneaten Feast triggers, causing you to gain 1 life.
17. Repeat.

This intricate recycling loop puts Warren Soultrader at the center of a sacrificial engine that continuously exploits Reveillark’s leaves-the-battlefield trigger to recur Boss's Chauffeur and Seedship Broodtender. As those creatures cycle back and forth, Case of the Uneaten Feast keeps your life total safely insulated from the costs while tracking every entering body, allowing Boss's Chauffeur to amass massive swarms of Citizen tokens. Those tokens feed right back into Warren Soultrader to generate the treasures and mana needed to replay Seedship Broodtender's resurrection ability, ultimately pulling Reveillark straight back to the field to do it all over again.
