Old Gnawbone
51% of multiplayer games where Old Gnawbone resolved ended in a win for its controller, a +21.4 percentage-point lift over games where it stayed buried in the library.
Old Gnawbone lands on the battlefield and wins games at a striking clip. Across 518 tracked multiplayer Commander games on Playgroup Live, the card posted a 51% win rate in participations where it was cast, compared to 30% when it never left the library. That +21.4 percentage-point gap is one of the larger deltas we see on any high-cost creature in the dataset, and with 101 and 314 observations in each bucket respectively, it carries real weight.
The card's mana cost of {5}{G}{G} means it rarely lands on curve in the traditional sense. Median first-cast turn sits at 7, well past when most ramp-heavy Dragon decks have assembled enough mana to force it through. Despite that, players cast it quickly once it's in hand: 43% of drawn-and-cast instances were played on the same turn the card was drawn. That's a strong signal that when Old Gnawbone finally arrives, it hits the table immediately.
The commander distribution tells the story you'd expect. The Ur-Dragon leads by a wide margin, but Old Gnawbone shows up across a surprisingly broad slice of the green meta, from treasure-synergy commanders like Korvold to combat-focused Gruul pairings. Its inclusion rate of 3% reflects its mythic rarity and seven-mana cost rather than any lack of desirability among green players who can support it.

n=115The "good card" funnel
542 brought · 218 playersOf 542 Old Gnawbones brought to tracked games, 149 were drawn, 115 of those were cast, and the majority stayed on the battlefield through the end of the game.
Players who cast this card win 51% of the time (n=101) , vs 30% when it never left the library (n=314).
When players drew this card but left it in hand, they won 23% (n=30) — about the same as leaving it in the library. Those players survived long enough to draw it, so the gap above is about the card resolving, not just about surviving.
Observed gap +21.4pp; 95% confidence interval +11.5pp to +31.3pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.

The Ur-Dragon dominates the commander list in raw count, but Old Gnawbone shows up across Dragon-tribal, Treasure-synergy, and combat-focused builds, pointing to a broadly playable card rather than a narrow tribal slot.
