Pir, Imaginative Rascal + Gemstone Array + Power Artifact

Pir, Imaginative Rascal

Gemstone Array

Power Artifact

How it works

1. Activate Gemstone Array's first ability by paying 1, putting two charge counters on it.
2. Activate Gemstone Array's second ability by removing a charge counter from it, adding 1.
3. Repeat.

This clever loop harnesses **Power Artifact** to slash the activation cost of **Gemstone Array** down to just a single generic mana, turning the artifact's energy conversion into a self-sustaining engine. Ordinarily, feeding that loop would merely break even, but the presence of **Pir, Imaginative Rascal** dramatically alters the math by adding an extra charge counter every single time one is placed. Because Gemstone Array gains two counters for the price of one while only requiring a single counter to be removed for mana, you are left with a net gain of floating mana and infinitely growing charge counters.
