Bristly Bill, Spine Sower + Cryptic Trilobite + Gemstone Array

Bristly Bill, Spine Sower

Cryptic Trilobite

Gemstone Array

How it works

1. Activate Bristly Bill by paying 3, doubling the number of +1/+1 counters on creatures you control.
2. Activate Cryptic Trilobite four times by removing four +1/+1 counters from it, adding eight C that can only be spent to activate abilities.
3. Activate Gemstone Array's first ability twice by paying 4, putting two charge counters on it.
4. Activate Gemstone Array's second ability twice by removing two charge counters from it, adding .
5. Repeat.

This clever loop relies on Cryptic Trilobite as a specialized battery, entering with enough counters to fuel its own ability while interacting with Gemstone Array to filter restricted energy into true colored mana. By activating Bristly Bill, Spine Sower to repeatedly double the creature's +1/+1 counters, the system generates a massive surplus of counters and restricted mana beyond what was originally invested. Gemstone Array then acts as the crucial conversion engine, turning that ability-only mana into the green mana required to pay Bristly Bill's doubling cost and keep the cascade going indefinitely.
