Agatha of the Vile Cauldron + Spawnsire of Ulamog

Agatha of the Vile Cauldron

Spawnsire of Ulamog

How it works

1. Activate Spawnsire of Ulamog's first ability by paying 1, creating two 0/1 Eldrazi Spawn creature tokens.
2. Activate an Eldrazi Spawn by sacrificing it, adding C.
3. Repeat.

This ingenious pairing rests on the reduction power of Agatha of the Vile Cauldron, whose static ability discounts the activated abilities of your creatures by an amount equal to her power. Since Spawnsire of Ulamog features an ability that normally costs four mana to create two Eldrazi Spawn tokens, Agatha makes that cost cheap enough to break the economy wide open. By feeding the resulting Eldrazi Spawn back into the loop for colorless mana, you generate infinite tokens, sacrifice triggers, and limitless mana to fuel whatever devastating finisher you desire.
