The "good card" funnel
717 brought · 315 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 25% of the time (n=109) , vs 24% when it never left the library (n=379).
When players drew this card but left it in hand, they won 23% (n=28).
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 +1.0pp; 95% confidence interval -4.3pp to +6.3pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.
