37
Once cast, 74% of this card is still on the battlefield at game end. This reflects how often it survives removal, not just whether it's a permanent.
≥ -7.3pp
Players who cast this card win 30% of the time (n=49) , vs 24% when it never left the library (n=190).
When players drew this card but left it in hand, they won 33% (n=24) — 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 +5.8pp; 95% confidence interval -7.3pp to +18.9pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.

Frequently Asked
Why isn't there more data on this card?
Playgroup Live collects per-card gameplay data from real Commander games. Basic play counts appear once a card reaches 100 tracked games; the full deep-dive page needs a larger, more diverse sample (at least 300 tracked games played by 10 or more different pilots, with no single pilot over 40 percent of the copies). Until this card clears those bars you're seeing only the basic counts. Stats refresh nightly.
How is Playgroup Live card data collected?
Players using Playgroup Live import their decklists before a game and log card actions as they play. Each cast, zone change, and resolution is recorded as a real game event. Stats on this site are computed from those events, not from decklist scrapes or theorycrafting.
