Spawnsire of Ulamog + Pitiless Plunderer

Spawnsire of Ulamog

Pitiless Plunderer

How it works

1. Activate Spawnsire of Ulamog's first ability by paying 4, creating two 0/1 Eldrazi Spawn creature tokens.
2. Activate the Eldrazi Spawns by sacrificing them, adding CC.
3. When the Eldrazi Spawns die, Pitiless Plunderer triggers twice, creating two Treasure artifact tokens.
4. Activate the Treasures by tapping and sacrificing them, adding 2.
5. Repeat.

By harnessing Pitiless Plunderer alongside Spawnsire of Ulamog, you turn the table's mana generation into a devastating feedback loop; every pair of Eldrazi Spawn tokens you create can be sacrificed for mana, and the resulting death triggers prompt the Plunderer to generate equivalent Treasure tokens to fund the next activation. Because the Treasure tokens yield any color of mana to help offset the cost, this continuous cycle loops seamlessly to churn out infinite creature sacrifices, entry triggers, and leaves-the-battlefield events.
