Simic Keyrune card art
Simic Keyrune produces blue or green mana and can become a 2/3 hexproof creature — reasonable flexibility, but three mana for a rock that enters tapped puts it below the bar for competitive Commander. It's a budget filler piece, not a staple.

Simic Keyrune is legal in Commander, Legacy, Modern, Pioneer, Vintage, and Oathbreaker, but it sees essentially zero play outside of Commander. In Commander, it fills a ramp slot in budget Simic builds where you've already run the two-mana options and need to go deeper — the creature mode with hexproof is occasionally relevant against targeted removal. In every other legal format, faster and more efficient mana options make Simic Keyrune a non-starter.

Price Context

Current price

$0.16 bulk tier

At $0.16, Simic Keyrune is deep bulk — you're not paying for power, you're paying for cardboard. It holds no meaningful value and won't appreciate, but if you need a placeholder ramp piece on a shoestring budget, the cost of entry is negligible.
