How it works

1. Activate Mikaeus' second ability by tapping it and removing a +1/+1 counter from it, putting two +1/+1 counters on each other creature you control.
2. Activate Crystalline Crawler's first ability twice by removing two +1/+1 counters from it, adding .
3. Activate Pemmin's Aura by paying , untapping Mikaeus.
4. Activate Mikaeus' first ability by tapping it, putting two +1/+1 counters on it.
5. Activate Pemmin's Aura by paying , untapping Mikaeus.
6. Repeat.

This clever loop relies on Loading Zone to supercharge the counter manipulation between your permanents, doubling every instance of counters placed on them. With Mikaeus, the Lunarch enchanted by Pemmin's Aura, you can continuously tap and untap Mikaeus to generate a surplus of +1/+1 counters on your board thanks to that replacement effect. Meanwhile, Crystalline Crawler acts as both your mana source and a repository that feeds the loop, letting you peel off counters for mana and easily rebuild them. The result is an explosive engine that completely breaks the economy of the game, generating infinite colored mana and infinitely large creatures.
