Agatha of the Vile Cauldron + Fire Nation Archers + Phyrexian Altar

Agatha of the Vile Cauldron

Fire Nation Archers

Phyrexian Altar

How it works

1. Activate Fire Nation Archers by paying 1, dealing 2 damage to each opponent and creating a 2/2 Soldier creature token.
2. Activate Phyrexian Altar by sacrificing the Soldier, adding .
3. Repeat

This clever loop turns your battlefield into an unstoppable engine by leveraging Agatha of the Vile Cauldron's cost-reduction ability. Because Agatha reduces the activation cost of creature abilities by her power (which defaults to 2), Fire Nation Archers' costly ability is discounted down to just a single generic mana. You pay that {1} to trigger the Archers, then feed the resulting 2/2 token into Phyrexian Altar to generate the exact red mana needed to fuel the next activation. The Altar provides the sacrifice outlet and mana generation to keep the cycle going forever, dealing infinite damage to your opponents through the Archers while racking up endless enter-the-battlefield, death, and sacrifice triggers.
