The "good card" funnel
1434 brought · 633 playersOnce cast, 94% 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 27% of the time (n=301) , vs 23% when it never left the library (n=720).
When players drew this card but left it in hand, they won 29% (n=31).
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 +3.8pp; 95% confidence interval +0.5pp to +7.1pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.
