Does a Turn-1 Sol Ring Win the Game?
Yes, and by less than the folklore says once there are four of you. In Playgroup Live games, a player who cast Sol Ring on their first turn won 62.2% of duels against a 50% fair share, and 28.7% of four-player games against 25%. Big in a duel, about four points in a four-player game.
62.2% against 49.5% for everyone else, in 2,028 duel players who cast it on turn 1.
Win rate with a turn-1 Sol Ring, against 25.0% for everyone else, or 1.15x the fair share. Real, and the least precise number on this page.
Playgroup Live games in which a deck ran Sol Ring, single winner, two to four players.
Does a turn-1 Sol Ring win the game?
More often than not being dealt one, yes. Across 26,712 Playgroup Live games where a deck ran Sol Ring, the player who cast it on turn 1 won 62.2% of duels, 41.1% of three-player games and 28.7% of four-player games. Fair share would be 50, 33 and 25.
The part the folklore gets wrong is the size. Twelve extra points in a duel is a different game. Four extra points in a four-player game is a real edge that decides roughly one game in 159 . Both are true at once, and which one you feel depends on the number of players.
Win rate after a turn-1 Sol Ring, by pod size
Single-winner games only. "Cast Sol Ring on turn 1" means the player put it on the battlefield before passing their own first turn, which is rules-independent and does not care who went first. Five-player games are not shown: 155 players is below the floor we publish at.
2,028 players cast it on turn 1. The dashed line is an even 1-in-2 share.
+12.7% over everyone else, 1.24x the fair share.
1,673 players cast it on turn 1. The dashed line is an even 1-in-3 share.
+7.9% over everyone else, 1.23x the fair share.
1,658 players cast it on turn 1. The dashed line is an even 1-in-4 share.
+3.7% over everyone else, 1.15x the fair share.
Bars are win rate; the dashed line marks an even share. The range under the teal bar is the 95% confidence interval. The gap shrinks with every extra player, which is arithmetic: a 25% fair share leaves less room than a 50% one.
Backing up the four-player number
A 25% base needs far more games than a 50% one to pin down a small effect, so the four-player cell is the one worth stress-testing. We looked at it three independent ways. Two clear zero, one just misses. Read together they say the same thing: about four points, real, and not to be quoted to a decimal.
| How we asked | Effect | 95% interval | Basis |
|---|---|---|---|
| Cast on turn 1 vs everyone else | +3.73% | +1.5 to +6.0 | 1,658 players who cast it, against every other player |
| Games where exactly one player opened with it | +3.96% | +1.1 to +7.0 | 1,162 four-player games: that player won 28.0%, each other player 24.0% |
| Dealt it in the top seven vs not (randomised) | +2.24% | -0.1 to +4.7 | 27.4% vs 25.1%, using the recorded shuffle as the assignment |
Expressed as odds inside each game, a player with a turn-1 Sol Ring in a four-player game has 1.127x the odds of winning (0.997 to 1.272). The randomised estimate sits lowest because it counts every player dealt the card, including the 38.0% that were dealt it and did not cast it on turn 1.
How we checked it against a real shuffle
Counting winners among people who cast Sol Ring on turn 1 has a catch: casting it on turn 1 means you kept a hand you liked, and good hands win. So we did what no decklist site can. Playgroup Live shuffles your library on the server and writes down where every card landed before anyone has seen a hand. Whether Sol Ring sat in your top seven is therefore decided by a random shuffle, not by you.
Players dealt Sol Ring in the opening seven won +7.04% more than players who were not, pooled across pod sizes, against +8.28% for the simple comparison. The two land about a point apart. That agreement is what makes the simple number publishable, and we only know it because of the shuffle.
| Dealt it in the top seven | Dealt | Not dealt | Difference | 95% interval |
|---|---|---|---|---|
| 2-player games | 61.0% | 49.8% | +11.24% | +8.8 to +13.6 |
| 3-player games | 40.5% | 33.4% | +7.11% | +4.5 to +9.8 |
| 4-player games | 27.4% | 25.1% | +2.24% | -0.1 to +4.7 |
- The shuffle is fair: across 61,899 99-card libraries, Sol Ring's position is flat (chi-squared 79.1 on 98 degrees of freedom, p = 0.92).
- Being dealt it does not depend on where you sit (p = 0.115) or on the deck's declared bracket (p = 0.206).
- Being dealt it changes behaviour the way you would expect: 62.0% of players dealt Sol Ring cast it on their first turn, against 4.4% of players who were not. Among players who kept their first hand, 79.2%.
The whole effect lives in the opening hand
Win index is your win rate divided by your fair share, so 1.0 means you won exactly as often as an even share and 1.18 means 18% more. Grouped by where Sol Ring sat in the shuffled library, there is a step at exactly the seven-card boundary and then nothing.
| Sol Ring's position in the shuffle | Players | Cast on turn 1 | Win index | 95% interval |
|---|---|---|---|---|
| Cards 1 to 7 (opening hand) | 4,652 | 62.0% | 1.177 | 1.135 to 1.218 |
| Cards 8 to 14 | 4,586 | 8.8% | 1.042 | 1.001 to 1.083 |
| Cards 15 to 21 | 4,656 | 4.1% | 1.003 | 0.963 to 1.044 |
| Cards 22 to 35 | 9,157 | 4.0% | 0.984 | 0.955 to 1.013 |
| Cards 50 to 63 | 9,213 | 4.3% | 0.974 | 0.946 to 1.003 |
| Cards 78 and deeper | 14,244 | 4.1% | 1.002 | 0.979 to 1.025 |
Whether Sol Ring was your 15th card or your 80th makes no measurable difference: -0.49% (-1.4 to +0.4). This is also why comparing turn-1 casts with later casts misleads: a player who cast it on turn 9 did not get better, they survived to turn 9.
It makes you win sooner, not survive longer
Winners who opened with Sol Ring closed the game in 8.09 rounds against 8.62 for other winners. Losers lasted 8.82 rounds either way. The card speeds up the games you were going to win; it does not rescue the ones you were not.
Nearly half of all turn-1 Sol Rings, 47.9%, are found after a mulligan. In duels, a Sol Ring off the dealt hand beat one found after a mulligan by +5.85% (64.9% against 59.0%). In three and four-player games that difference is inside the noise.
How often it happens: 7.46% of all players cast a first-turn Sol Ring, and at least one shows up in 14.1% of duels, 20.7% of three-player games and 26.2% of four-player games.
The only card of 143
A fair test should find nothing for a card that does nothing. So, as a control, we ran the same shuffle test on every card played in at least 6,000 of these decks, 143 in all. The average effect across them is -0.041 points , which is what a fair test should return. One card stands out.
| Card | Decks | Dealt in top 7, effect | 95% interval | Survives correction |
|---|---|---|---|---|
| Sol Ring | 64,847 | +7.04% | +5.6 to +8.5 | Yes |
| Arcane Signet | 54,412 | +2.56% | +1.0 to +4.1 | No (q = 0.058) |
| Command Tower | 56,042 | -0.03% | -1.6 to +1.5 | No (q = 0.99) |
| Rhystic Study | 8,186 | -0.51% | -4.5 to +3.4 | No (q = 0.99) |
| Mind Stone | 9,875 | -2.57% | -6.2 to +1.0 | No (q = 0.78) |
"Survives correction" means the effect is still there after adjusting for the fact that we tested 143 cards at once, which by chance alone would hand a few of them a false positive. Command Tower at almost exactly zero on 56,000 decks is the test passing on a card that should do nothing. Arcane Signet shows a small effect that does not clear the bar.
What this page does not say
- It does not say whether you should run Sol Ring. Decks that run it do win more than decks that do not, but that comparison is not randomised: the decks without it are mostly untouched precons and budget builds. This page is about what happens when it lands on turn 1.
- It does not say the card is too good. That is a judgement about the format. What the data adds is a size: large in duels, about four points in a four-player game.
- It does not cover five-player games, cEDH, or paper play. These are Playgroup Live browser games, and duels are 37% of them.
Method and caveats
- Games from Playgroup Live , our free in-browser virtual tabletop, between 26 Mar 2026 and 7 Sep 2026: 27,329 games with card-level logging and 8,235 different players. Ended, not solo, exactly one winner, two to six players.
- The analysis covers players whose deck contained Sol Ring and who played a land on their first turn: 64,847 player-games (one player in one game) across 26,712 games. Dropping the land condition moves the headline by 0.01 points.
- "Cast on turn 1" is the Sol Ring battlefield event before that player's own first pass of the turn. This avoids a trap in client-stamped turn numbers that over-counts the starting player's first turn.
- The randomised check uses the library position recorded at game start, which later shuffles never overwrite. Tutoring a Sol Ring changes when it is cast, never where it was dealt, so the assignment holds.
- Intervals are 95% confidence intervals. The direct comparison and the randomised estimate answer slightly different questions and are shown side by side on purpose.
- This page is a frozen snapshot of the audit, not a live feed. The full working, including everything we chose not to publish, is in our research notes.
