Chain of Acid + Quandrix Pledgemage

Chain of Acid

Quandrix Pledgemage

How it works

1. Cast Chain of Acid by paying 3, targeting an indestructible noncreature permanent you control.
2. Quandrix Pledgemage triggers, putting a +1/+1 counter on it.
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 relies on targeting your own indestructible noncreature permanent with Chain of Acid, ensuring the spell resolves safely without actually removing anything while still triggering its copy clause. Because Chain of Acid forces its controller to copy it, you can continuously redirect the copies right back at your indestructible target to keep the chain alive indefinitely. Every single iteration of this spell copying process directly fuels Quandrix Pledgemage's magecraft ability, allowing you to pile an endless number of +1/+1 counters onto your creature.
