Seedship Broodtender

Reveillark

Boss's Chauffeur

Embalmed Ascendant

How it works

1. Activate Warren Soultrader by paying 1 life and sacrificing Reveillark.
2. When Reveillark dies, it and Embalmed Ascendant trigger.
3. Resolve the Embalmed Ascendant trigger, causing you to gain 1 life and each opponent to lose 1 life.
4. Resolve the Reveillark trigger, 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.
5. When Seedship Broodtender enters, it and Boss's Chauffeur trigger, causing you to mill three cards and put a +1/+1 counter on Boss's Chauffeur.
6. Resolve the Warren Soultrader ability, creating a Treasure token.
7. Activate Warren Soultrader by paying 1 life and sacrificing Boss's Chauffeur.
8. When Boss's Chauffeur dies, it and Embalmed Ascendant trigger.
9. Resolve the Embalmed Ascendant trigger, causing you to gain 1 life and each opponent to lose 1 life.
10. Resolve the Boss's Chauffeur trigger, creating a 1/1 Citizen creature token for each +1/+1 counter on it.
11. Resolve the Warren Soultrader ability, creating a Treasure token.
12. Activate Warren Soultrader by paying 1 life and sacrificing a Citizen.
13. When the Citizen dies, Embalmed Ascendant triggers, causing you to gain 1 life and each opponent to lose 1 life.
14. Resolve the Warren Soultrader ability, creating a Treasure token.
15. Repeat from step 12 two additional times.
16. Activate five Treasures by tapping and sacrificing them, adding 3.
17. Activate Seedship Broodtender by paying 3 and sacrificing it.
18. When Seedship Broodtender dies, Embalmed Ascendant triggers, causing you to gain 1 life and each opponent to lose 1 life.
19. Resolve the Seedship Broodtender ability, returning Reveillark from your graveyard to the battlefield.
20. Repeat.

This intricate loop turns Warren Soultrader into a lethal sacrifice engine by leveraging the recursive power of Reveillark. When Reveillark hits the graveyard, its departure triggers the return of Seedship Broodtender and Boss's Chauffeur, fueling your board state while Embalmed Ascendant quietly ensures your opponents bleed out with every creature death achieved through its max speed static ability. Boss's Chauffeur grows with your expanding board to generate sacrificial Citizen tokens, and Seedship Broodtender eventually spends the accumulated Treasure mana to resurrect Reveillark and start the cycle all over again.
