The "good card" funnel
1946 brought · 800 playersOnce cast, 93% 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 25% of the time (n=414) , vs 25% when it never left the library (n=1031).
When players drew this card but left it in hand, they won 31% (n=57).
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 -0.3pp; 95% confidence interval -3.2pp to +2.5pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.
