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, Impassioned Orator and Boss's Chauffeur trigger.
4. Resolve the Impassioned Orator trigger, causing you to gain 1 life.
5. Resolve the Boss's Chauffeur trigger, putting a +1/+1 counter on Boss's Chauffeur.
6. Resolve the Seedship Broodtender trigger, causing you to mill three cards.
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, Impassioned Orator 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, Impassioned Orator triggers, causing you to gain 1 life.
17. Repeat.

This intricate loop transforms a quiet graveyard into an overwhelming engine of life, mana, and tokens, anchored by Warren Soultrader as the ultimate sacrifice outlet. By feeding creatures to Warren Soultrader, you trigger Reveillark's leaves-the-battlefield ability to pull Seedship Broodtender and Boss's Chauffeur right back from the dead. Meanwhile, Impassioned Orator quietly offsets the life payments with a steady stream of healing every time a new creature joins the fray. Boss's Chauffeur accumulates counters through its own alliance ability and the steady churn of entries, eventually bursting into an army of Citizen tokens upon death that help fuel the mana generation needed for Seedship Broodtender to recycle Reveillark all over again.
