Urtet, Remnant of Memnarch + Crystalline Crawler + Pemmin's Aura + Maskwood Nexus + Doubling Season

Urtet, Remnant of Memnarch

Crystalline Crawler

Pemmin's Aura

Maskwood Nexus

Doubling Season

How it works

1. Activate Urtet by paying and tapping it, putting six +1/+1 counters on each creature you control, as they are all Myrs due to Maskwood Nexus.
2. Activate Crystalline Crawler's first ability six times by removing six +1/+1 counters from it, adding .
3. Activate Pemmin's Aura's first ability by paying , untapping Urtet.
4. Repeat.

This mesmerizing loop turns a modest board of metal into a boundless fountain of growth by leveraging Maskwood Nexus to make every creature you control count as a Myr for Urtet, Remnant of Memnarch. Doubling Season supercharges this synergy, ensuring that Urtet's activated ability heaps twice as many +1/+1 counters onto your permanent base—including Crystalline Crawler. You then strip those freshly minted counters right off Crystalline Crawler to generate the exact five-color mana required to pay Urtet's activation cost again. Finally, the blue mana left over in your pool fuels Pemmin's Aura to untap Urtet endlessly, closing the circuit for infinite mana and infinite +1/+1 counters.
