Boros Signet appears in 16% of tracked Commander decks on Playgroup Live. When drawn, 75% of copies reach the battlefield, with a median first-cast turn of 4.0.

Boros Signet is the go-to mana rock for any red-white deck that wants to smooth out its early turns. Across 623 tracked multiplayer games on Playgroup Live, it sits in 16% of participating decks, appearing in 346 of the 2163 distinct decklists that have played a live game.

The card earns its slot through consistency. 75% of drawn copies are cast before the game ends, and once it resolves, 84% of copies remain on the battlefield through the end of the game. Median first cast lands on turn 4.0, exactly on-curve for a 2-mana artifact, and the mode of the cast-turn distribution is also turn 2, meaning a plurality of copies hit the table the earliest possible moment.

The commander spread is broad: Kaalia of the Vast and Zinnia, Valley's Voice both lead the top-commander list, reflecting how naturally Boros Signet fits any deck touching red and white. Its 4.2% inclusion rate across the wider deck-building dataset suggests room to grow beyond its current core adopters.

≥ -8.3pp

Players who cast this card win 24% of the time (n=125) , vs 24% when it never left the library (n=433).

When players drew this card but left it in hand, they won 27% (n=40) — 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 -0.6pp; 95% confidence interval -8.3pp to +7.1pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.

Most Boros Signets that enter a game never leave the library, a structural fact of 100-card singleton decks. Among observed copies, the battlefield is the most common final zone, consistent with its high stickiness rating.

The top-commander list spans pure Boros through three-color Mardu builds, signaling that Boros Signet is adopted wherever red and white share a deck rather than clustering around any single strategy.

Frequently Asked

How often is Boros Signet drawn in a Commander game?

In 623 tracked games where Boros Signet was in the deck, it was drawn 26% of the time. That is a typical draw rate for a singleton in a 100-card deck. Of 171 instances that reached a player's hand, 75% were cast before the game ended. The remainder reflects copies drawn late in games that concluded before the mana was needed.

What turn does Boros Signet usually get cast?

Median first-cast turn is 4.0, and turn 2 is the single most common cast turn in the distribution. 41% of tracked casts landed exactly on curve (turn 2 for a 2-mana card). A sizeable cluster arrived earlier than turn 2 thanks to ramp or fast mana, while the remainder were drawn later in the game and cast as needed. The median landing right on the card's mana value is a strong signal that players prioritize it when they have it early.

Does casting Boros Signet correlate with winning?

In 125 participations where Boros Signet reached the battlefield, the normalized win rate was 24%, compared to 24% in participations where it never left the library. The delta is very small and the confidence interval on this sample crosses zero, so treat this as directional rather than conclusive. Boros Signet's value is better understood as infrastructure than as a direct win driver.

Is Boros Signet legal in Commander and other formats?

Boros Signet is legal in Commander, Duel Commander, Legacy, Modern, Pauper, Vintage, Historic, Timeless, Oathbreaker, and Pauper Commander, among others. It is not legal in Standard, Pioneer, Alchemy, or Penny Dreadful. In Commander it is unrestricted, which is why it appears across such a wide range of red-white and Mardu builds.

Which commanders most often run Boros Signet?

Kaalia of the Vast and Zinnia, Valley's Voice each lead the top-commander list in tracked multiplayer games. Lorehold, the Historian, Queen Marchesa, and Isshin, Two Heavens as One also appear prominently. The spread across Mardu (B/R/W) and pure Boros (R/W) commanders confirms the Signet is a color-identity staple rather than a niche synergy pick.

How concentrated is the Boros Signet data among specific players?

The data is well-distributed. 291 distinct players have brought Boros Signet to a tracked game, and the single heaviest contributor accounts for only 3% of all instances. That spread strengthens confidence in the draw and cast figures, since no single player's habits are driving the aggregate numbers.
