The "good card" funnel
954 brought · 408 playersOnce cast, 85% 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 20% of the time (n=107) , vs 23% when it never left the library (n=562).
When players drew this card but left it in hand, they won 24% (n=24).
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 -2.7pp; 95% confidence interval -7.8pp to +2.3pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.
