Chain of Acid + Deekah, Fractal Theorist

Chain of Acid

Deekah, Fractal Theorist

How it works

1. Cast Chain of Acid by paying 3, targeting any indestructible noncreature permanent you control.
2. Deekah triggers, creating a 0/0 Fractal creature token with four +1/+1 counters on it.
3. Resolve Chain of Acid, failing to destroy the indestructible permanent and choosing to copy Chain of Acid, targeting the indestructible permanent with the copy.
4. Repeat from step 2.
