Koilos Roc is a 3/2 flyer for three mana that puts a +1/+1 counter on itself whenever you gain life — a reasonable rate with a relevant upside in any life-gain shell. The ceiling is real if you're triggering life gain repeatedly, but outside that synergy it's just a vanilla 3/2 with wings.

In Commander, Koilos Roc earns a slot in dedicated life-gain decks where it grows reliably and flies over ground-based blockers — it's not a staple, but it fills a role at the bottom of the curve. In Pauper, the common slot is competitive and a 3/2 flyer for three that requires setup to exceed its base stats rarely makes the cut over more consistent threats. Modern, Pioneer, and Legacy all have far more efficient options at this mana cost, so Koilos Roc doesn't register in those formats outside of budget casual play.

Price Context
Current price
$0.05 bulk tier
At $0.05, Koilos Roc is deep bulk — you're picking it out of a commons box, not buying singles. There's no meaningful price floor to protect here, and bulk commons with niche synergy requirements rarely appreciate.
