Tale of Katara and Toph + Animation Module + Song of Freyalise + Yarus, Roar of the Old Gods

Tale of Katara and Toph

Animation Module

Song of Freyalise

Yarus, Roar of the Old Gods

How it works

1. Activate a creature by tapping it, adding 1.
2. The creature's ability granted to it by Tale of Katara and Toph triggers, putting a +1/+1 counter on the creature.
3. Animation Module triggers, causing you to pay 1 to create a 1/1 Servo artifact creature token.
4. Repeat.

This loop transforms a simple tap for mana into a cascading engine by turning your creatures' own activation costs into growth catalysts. With Song of Freyalise providing the necessary mana-tapping ability to every creature you control, tapping a creature triggers Tale of Katara and Toph to drop a +1/+1 counter on it the first time it taps each turn. That counter sighting instantly wakes up Animation Module, allowing you to feed the mana you just generated right back into the Module to churn out a fresh Servo token. While Yarus, Roar of the Old Gods watches from the sidelines ready to grant haste to your new arrivals or leverage its other face-down triggers, the interplay between the Saga's mana-granting aura, the Katara and Toph enchantment, and the Module's looping token generation lets you flood the board with an infinite army of artifacts and creatures.
