The Soul Stone
80% of drawn Soul Stones are cast before the game ends, and decks that resolve it win 32% of the time versus 26% when it stays buried in the library.
The Soul Stone is a mythic black artifact from Marvel's Spider-Man that doubles as mana acceleration and a repeating reanimation engine once harnessed. Across 949 tracked multiplayer Commander games on Playgroup Live, 80% of copies that reached a player's hand were cast before the game concluded.
The cast-versus-library win-rate gap sits at +6.2 percentage points: 32% when the Stone resolved versus 26% when it never left the library. Both sample sizes are large enough to treat this as a meaningful directional signal, though Playgroup Live's dataset is still growing and the gap should be read as early evidence rather than a settled conclusion. Median first cast lands on turn 5, which is late relative to its 2-mana cost, consistent with players drawing it after the early game has passed.
The Stone fits most naturally into mono-black and black-heavy shells that can supply the 7-mana activation cost and want a steady stream of creatures returning from the graveyard. Its indestructible body also provides a durable mana rock in the early turns before harnessing becomes relevant. At 5% inclusion across tracked decks, it is a focused staple rather than a universal one, concentrated in reanimator and villain-tribal strategies.

First-cast turn
n=199The "good card" funnel
1003 brought · 379 playersOf 1003 Soul Stones brought to multiplayer games, 249 were drawn, 199 of those were cast, and the majority remained on the battlefield through the end of the game.
Players who cast this card win 32% of the time (n=183) , vs 26% when it never left the library (n=627).
When players drew this card but left it in hand, they won 34% (n=47) — 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 +6.2pp; 95% confidence interval -0.8pp to +13.2pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.
Final zone distribution
278 instancesMost observed Soul Stones end on the battlefield rather than the library, a direct result of its indestructible body making removal much harder than for a typical artifact.
