Mox Opal
83% of drawn Mox Opals are cast before the game ends, and the median first cast lands on turn 4, making it one of the fastest mana rocks tracked on Playgroup Live.
Mox Opal is a zero-mana mythic artifact that generates one mana of any color under Metalcraft, meaning it asks you to build around it rather than slot it anywhere. Across 425 tracked multiplayer Commander games, 83% of drawn copies were cast before the game ended, a figure that reflects how quickly artifact-dense decks can activate Metalcraft and put the Mox to work.
Inclusion sits at 3% across tracked decks, which is narrow by design. Mox Opal rewards dedicated artifact strategies: Urza, Kinnan, Breya, and Shorikai all appear in its top-commander list. The card is colorless, so it fits any color identity, but the Metalcraft condition means it underperforms in non-artifact builds and experienced players know it.
The data is well-spread: 181 distinct players have brought Mox Opal to a tracked game, and no single player accounts for more than 83% of the dataset. Read these numbers as a broad early signal across a real cross-section of the Playgroup Live player base, not a single pilot's result.

First-cast turn
n=115The "good card" funnel
523 brought · 181 playersOf 523 Mox Opals brought to multiplayer games, 139 were drawn, 115 of those were cast, and 88% of cast copies remained on the battlefield through end of game.
Players who cast this card win 31% of the time (n=112) , vs 26% when it never left the library (n=343).
When players drew this card but left it in hand, they won 35% (n=24) — 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 +4.7pp; 95% confidence interval -3.8pp to +13.2pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.
Final zone distribution
153 instancesThe vast majority of Mox Opals finish on the battlefield once cast. Most copies that never leave the library simply were not drawn, a structural reality of 100-card singleton rather than any hesitation to play it.
