The "good card" funnel
4443 brought · 1612 playersOnce cast, 95% 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.
Players who cast this card win 28% of the time (n=623) , vs 25% when it never left the library (n=2419).
When players drew this card but left it in hand, they won 33% (n=162).
Read this as correlation, not as the card's contribution. Casting a card means you lived long enough to cast it, so this gap widens with mana value across every card we track.
Observed gap +2.6pp; 95% confidence interval +0.4pp to +4.8pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.
