How it works

1. Activate Warren Soultrader by paying 1 life and sacrificing Reveillark.

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.

This intricate loop is masterminded by Warren Soultrader, whose ability to sacrifice creatures for Treasures turns your board state into a dynamic engine. Reveillark acts as the recurring pivot, dragging Seedship Broodtender and Boss's Chauffeur back from the dead to continually fuel the sacrifice chain and swell your counter counts. Meanwhile, Lifecreed Duo gracefully tracks every single entry into the battlefield to steadily pad your life total, ensuring you never run out of health to pay for Warren Soultrader's costs.
