Chain of Acid + Witherbloom Pledgemage

Chain of Acid

Witherbloom Pledgemage

How it works

1. Cast Chain of Acid by paying 3, targeting an indestructible noncreature permanent you control.
2. Witherbloom Pledgemage triggers, causing you to gain 1 life.
3. Resolve Chain of Acid, destroying nothing and causing you to copy Chain of Acid, targeting an indestructible noncreature permanent you control.
4. Repeat from step 2.

This clever loop turns Chain of Acid's cascading copy clause into a perpetual motion machine by targeting an indestructible noncreature permanent you already control, ensuring the target survives to endlessly repeat the process. As the copies bounce back and forth, Witherbloom Pledgemage acts as the engine's beneficiary, feeding on every single copy created via its magecraft ability to pile up infinite life.
