Krasis Incubation + Crystalline Crawler + Zirda, the Dawnwaker + Semblance Anvil + Branching Evolution

Krasis Incubation

Crystalline Crawler

Zirda, the Dawnwaker

Semblance Anvil

Branching Evolution

How it works

1. Activate Krasis Incubation by paying and returning it to your hand, putting four +1/+1 counters on Crystalline Crawler.
2. Activate Crystalline Crawler's first ability four times by removing four +1/+1 counters from it, adding .
3. Cast Krasis Incubation by paying due to Semblance Anvil, attaching it to Crystalline Crawler.
4. Repeat.

This intricate loop turns a simple Aura bounce into an engine for infinite storm count by exploiting heavy cost reductions and exponential counter growth. With Semblance Anvil discounting your enchantment spells, Krasis Incubation becomes cheap enough to replay continuously, and Zirda, the Dawnwaker steps in to make the Aura's return activation cost just {G}{U}. Every time Krasis Incubation is bounced and recast onto Crystalline Crawler, Branching Evolution doubles the incoming counters to supercharge the Crawler, leaving you with more than enough mana from Crystalline Crawler to repeat the cycle indefinitely.
