Genku, Future Shaper + Crystalline Crawler + Cryptic Trilobite + Lae'zel, Vlaakith's Champion

Genku, Future Shaper

Crystalline Crawler

Cryptic Trilobite

Lae'zel, Vlaakith's Champion

How it works

1. Activate Genku by paying 3, putting two +1/+1 counters on each creature you control due to Lae'zel, Vlaakith's Champion.
2. Activate Cryptic Trilobite's first ability twice by removing two +1/+1 counters from it, adding CCCC that can only be spent to activate abilities.
3. Activate Crystalline Crawler's first ability twice by removing two +1/+1 counters from it, adding .
4. Repeat.
5. Once you have infinite C, you may forego removing counters from Cryptic Trilobite.

This fascinating loop relies on Genku, Future Shaper fueling an engine where counters effortlessly convert into the exact mana needed to keep the cycle spinning. Crystalline Crawler and Cryptic Trilobite act as your batteries, tapping and stripping away their own +1/+1 counters for mana, while Lae'zel, Vlaakith's Champion ensures that when Genku's activated ability pumps your board, you net an extra counter every time. Because those counters are continually replenished and expanded upon, you can endlessly pay Genku's steep mana cost using the exact resources your creatures generate, creating an abundance of colorless ability-mana and infinite growth for your board.
