Mox Amber
85% of drawn Mox Ambers are cast before the game ends, with a median first-cast turn of 4 across 445 tracked Commander games on Playgroup Live.
Mox Amber is cast in nearly every game where a player draws it. Across 445 tracked multiplayer Commander games, 85% of drawn copies reached the battlefield, with a median first-cast turn of 4.
The card's dependency on a legendary permanent is its primary constraint. When a player has a commander in play, Mox Amber fires immediately: 83% of cast copies go down the same turn they are drawn. That urgency is consistent with how free mana rocks behave in faster pods. Inclusion sits at 3% across tracked decks, which reflects how narrowly the card fits: it demands a legendary creature or planeswalker to generate any mana at all, so it concentrates in commander-centric and legendary-tribal builds.
The commander spread is broad. 192 distinct players have brought Mox Amber to a tracked game, and no single player accounts for more than a small share of total instances, giving the dataset reasonable coverage across different archetypes and play styles.

First-cast turn
n=129The "good card" funnel
516 brought · 192 playersOf 516 Mox Ambers brought to games, 151 were drawn, 129 of those were cast, and 85% of cast copies stayed on the battlefield through end of game.
Players who cast this card win 37% of the time (n=122) , vs 24% when it never left the library (n=325).
When players drew this card but left it in hand, they won 23% (n=22) — about the same as leaving it in the library. Those players survived long enough to draw it, so the gap above is about the card resolving, not just about surviving.
Observed gap +13.0pp; 95% confidence interval +4.5pp to +21.5pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.
Final zone distribution
164 instancesMost Mox Ambers finish on the battlefield rather than in the library, an unusually active final-zone profile that reflects how quickly the card is cast once drawn.
