Boros Keyrune produces red or white mana and can become a 1/1 double striker — useful in narrow combat situations, but three mana for a rock that taps for one is a structural problem in 2024 Commander. Cheaper, faster options exist at every turn, and the creature mode rarely justifies the slot.

Boros Keyrune sees virtually no play in competitive formats — Legacy, Modern, Vintage, and Pioneer all have access to mana acceleration that laps it on rate, and the creature mode offers nothing relevant in those contexts. Commander is where Boros Keyrune lives, and even there it sits at the bottom of the mana rock pecking order: three mana to tap for one is a tempo loss, and the animating ability doesn't offset that unless you're in a dedicated equipment or double-strike payoff shell. It's a passable budget filler if your Boros deck is freshly built and short on two-drop rocks, but it should be the first cut once you're upgrading.

Price Context
Current price
$0.20 bulk tier
At $0.20, Boros Keyrune is deep bulk — it costs less than a sleeve and that price reflects its power level accurately. Don't expect it to appreciate; there are multiple printings and no competitive demand driving it anywhere.
