Genku, Future Shaper + Crystalline Crawler + Cryptic Trilobite + Hardened Scales

Genku, Future Shaper

Crystalline Crawler

Cryptic Trilobite

Hardened Scales

How it works

1. Activate Genku by paying 3, putting two +1/+1 counters on each creature you control due to Hardened Scales.
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 clever interaction transforms mana-producing artifact creatures into an engine fueled by a clever exchange of counters. Crystalline Crawler and Cryptic Trilobite start with the necessary counters to tap into their abilities for mana, and every time counters are added back, Hardened Scales ensures that growth is amplified by dropping an extra +1/+1 counter onto them. Meanwhile, Genku, Future Shaper sits as the quiet architect of the battlefield, ready to reward your permanent management, though the real magic here is the self-sustaining loop between the two modular artifact creatures and the counter-boosting enchantment that generates infinite colorless mana for abilities and piles of +1/+1 counters on your team.
