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, Healer of the Pride and Boss's Chauffeur trigger.
4. Resolve the Healer of the Pride trigger, causing you to gain 2 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, Healer of the Pride triggers that many times, causing you to gain twice 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, Healer of the Pride triggers, causing you to gain 2 life.
17. Repeat.

This intricate loop transforms a graveyard full of small creatures into an overwhelming engine of life, mana, and tokens. Warren Soultrader acts as the ultimate sacrifice outlet, fueling the loop by turning your creatures into Treasures while Reveillark gracefully shuttles your fallen threats back from the graveyard. As Seedship Broodtender and Boss's Chauffeur repeatedly enter and leave the battlefield, Healer of the Pride capitalizes on every single arrival to continuously pad your life total. Meanwhile, Boss's Chauffeur grows larger with each iteration before cashing out its accumulated +1/+1 counters into an army of Citizen tokens, ensuring you have a steady supply of fodder to keep the whole machine running.
