Aetherstorm Roc card art
Aetherstorm Roc turns energy into a self-growing threat and a tap-down control piece — the cost is four mana for a creature that does nothing without an energy engine behind it. In decks that already generate energy in volume, like anything built around Satya, Aetherflux Genius or Aethergeode Miner, the Roc snowballs quickly; outside that context, it's a vanilla 3/3 with upside that never triggers.

Satya, Aetherflux Genius

Satya, Aetherflux Genius

70.1% of decks · synergy 0.65

Satya, Aetherflux Genius is the natural home — she generates energy on every attack, and Aetherstorm Roc converts that energy into +1/+1 counters and creature taps that clear the way for the next swing, creating a tight attack-trigger loop that compounds each combat.

02
Dr. Madison Li

Dr. Madison Li

26.0% of decks · synergy 0.21

Dr. Madison Li rewards artifact and energy synergies, and Aetherstorm Roc slots in as a repeatable energy sink that doubles as board control, tapping down blockers or key utility creatures each time Dr. Madison Li's engine feeds it.

Format Analysis

Where it lives, where it can’t

FormatVerdict
commander legal
legacy legal
modern legal
pioneer legal
standard not legal
vintage legal
pauper not legal
oathbreaker legal

Aetherstorm Roc is legal in Commander, Legacy, Modern, Pioneer, Vintage, and Oathbreaker, but it's a Commander card in practice — the 60-card formats have no interest in a four-mana 3/3 whose power depends on energy density, and energy as an archetype is too fragile in Legacy and Vintage to support it. In Modern and Pioneer, dedicated energy shells exist, but Aetherstorm Roc is too slow and too low-impact compared to what those decks actually want. Commander is where it lives, specifically in energy-focused builds where the tap ability functions as repeated pseudo-removal and the counter accumulation makes it a genuine late-game threat.

Price Context

Current price

$0.10 bulk tier

At $0.10, Aetherstorm Roc is deep bulk — you're not paying for it, you're finding it in a common box. That price reflects real demand: it's a niche card that only performs in a narrow slice of Commander builds, so don't expect movement.
