Mana Geyser
43% of multiplayer games where Mana Geyser resolved ended in a win for the caster, a +18.4 percentage-point lift over the 25% baseline when the card never left the library.
Mana Geyser resolves and wins. Across 796 tracked multiplayer Commander games on Playgroup Live, players who cast it won 43% of those games, compared to 25% when the card sat unplayed in the library. That +18.4-point gap is the clearest signal in the data, drawn from 105 cast observations and 557 library observations.
The card is a late-game engine, not an early play. Median first cast lands on turn 6.0, well after opponents have had time to develop a full board of tapped lands. Of the 188 copies drawn across tracked games, 57% reached the stack before the game ended. Players typically hold it for a median of 2 turns after drawing before casting. 40% cast it on the same turn they drew it, meaning most are waiting for the right window.
Mana Geyser is a common from a format staple set, legal in Commander and Pauper Commander, and banned in Oathbreaker. It appears in 492 of the 5956 distinct decks tracked on Playgroup Live, an 8% inclusion rate that reflects its narrow but dedicated home in red spell-slinger and big-mana strategies.

First-cast turn
n=108The "good card" funnel
838 brought · 411 playersOf 838 Mana Geysers brought to games, 188 were drawn, 108 of those were cast, and the vast majority resolved straight to the graveyard as expected for a sorcery.
Players who cast this card win 43% of the time (n=105) , vs 25% when it never left the library (n=557).
When players drew this card but left it in hand, they won 29% (n=74) — 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 +18.4pp; 95% confidence interval +9.1pp to +27.7pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.
Final zone distribution
216 instancesMost Mana Geyser copies end the game in the graveyard after resolving, which is exactly right for a sorcery: it fires once, generates a large burst of red mana, and goes to the bin.
