Conversion Apparatus converts excess energy into artifact tokens and feeds those tokens back into more energy, making it a self-sustaining loop piece in the right shell. In Satya, Aetherflux Genius decks specifically, it does exactly what the engine demands — and for two mana, the cost is trivial.
Best Commanders
Commanders with the highest synergy
Satya, Aetherflux Genius
Satya, Aetherflux Genius creates token copies of artifacts that enter tapped and attacking, and Conversion Apparatus turns those tokens into energy while also spending energy to make more tokens — the two cards form a closed loop that fuels Satya's whole game plan.
Dr. Madison Li
Dr. Madison Li rewards you for crafting artifacts, and Conversion Apparatus produces the Clue tokens she wants while converting energy into bodies, making it a reliable source of both artifact ETBs and card advantage triggers.
Saheeli, Radiant Creator
Saheeli, Radiant Creator cares about artifacts entering and copying them for value, and Conversion Apparatus generates a stream of artifact tokens that she can interact with while the energy exchange keeps the machine running.
Liberty Prime, Recharged
Liberty Prime, Recharged needs a critical mass of artifact permanents to threaten its win conditions, and Conversion Apparatus supplies a steady trickle of Servo tokens while the energy payoff adds incremental advantage.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |
|---|---|
| commander | legal |
| legacy | legal |
| modern | not legal |
| pioneer | not legal |
| standard | not legal |
| vintage | legal |
| pauper | not legal |
| oathbreaker | legal |
Conversion Apparatus is legal in Commander, Legacy, Vintage, and Oathbreaker, but it's effectively a Commander card — Legacy and Vintage have no interest in a two-mana artifact that produces energy and tokens at sorcery speed. In Commander it earns its slot almost exclusively in energy-matters or artifact-token decks, where the synergy density makes both halves of the card live. Outside those shells, it's too low-impact to justify a slot.

Price Context
Current price
$0.35 bulk tier
At $0.35, Conversion Apparatus sits firmly in bulk territory — pick it up without a second thought if it fits your build. Bulk artifact role-players like this rarely climb in price unless a new commander dramatically spikes demand, so don't expect appreciation.
