Tale of Katara and Toph

Animation Module

Jinnie Fay, Jetmir's Second

Enduring Vitality

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 2/2 Cat creature token with haste due to Jinnie Fay.
4. Repeat.
