Aetherstorm Roc - Commander: Modern Horizons 3 (Rare) [M3C-164]

Aetherstorm Roc is a 3/3 Bird creature from Modern Horizons 3 Commander with flying, and it generates energy counters whenever it or another creature enters the battlefield under your control. When it attacks, you can spend two energy counters to give it a +1/+1 counter and tap down a creature your opponent controls, making it a solid choice in energy-focused or creature-heavy strategies. However, its effectiveness depends on having enough creatures to consistently generate energy and the right timing to maximise its tap ability.
