Ravnica: Clue Edition (CLU)
72.5% of drawn Dimir Signets are cast before the game ends, and decks that cast it win 40% of the time versus 26.8% when it stays in the library. A +13.2-point delta is the strongest directional signal in its stat line.
Dimir Signet sits in 5.5% of the 1,704 Commander decks tracked on Playgroup Live. That narrow slice reflects its strict blue-black color identity restriction, not a judgment on its power. Among the decks that can run it, this two-mana rock is a reliable mana accelerant that reaches the battlefield in 72.5% of the instances it is drawn.
The clearest signal is the win-rate delta. Participations where Dimir Signet was actually cast show a 40% win rate, compared to 26.8% when the card sat in the library all game. That +13.2-point gap is consistent with what we see from two-mana ramp in general: getting ahead on mana in turns 2 and 3 compounds into mid-game advantages. Both sample buckets (30 cast, 97 library) are large enough to treat this as a directional finding, though the dataset is still growing.
The median first-cast turn of 3 tells the deployment story. Dimir Signet is a two-mana card most often cast a turn behind curve, which is typical for a singleton drawn mid-game rather than in the opening hand. When it does show up early, the impact is felt: 30% of casts land on-curve or ahead of it.

First-cast turn
n=39The "good card" funnel
181 brought137 Dimir Signets were brought to games, 40 were drawn, 30 of those were cast, and 24 were still on the battlefield when the game ended. That 80% stickiness number shows the card is rarely answered once it resolves.
Players who cast this card win 38% of the time (n=39) , vs 24% when it never left the library (n=129).
Final zone distribution
181 instances97 of 137 Dimir Signets brought to games never left the library. That is the structural reality of a singleton in a 100-card deck, not a knock on the card's performance when it does appear.

How often is Dimir Signet actually drawn in a Commander game? ▾
Across 136 deck-participations tracked on Playgroup Live, Dimir Signet was drawn in 29.2% of them. That is modestly above the expected rate for a singleton in a 100-card deck, which suggests it is finding its way into opening hands with some regularity. Of those 40 drawn instances, 30 were cast, giving a draw-to-play rate of 72.5%.
Does casting Dimir Signet actually improve your win rate? ▾
The data so far says yes, directionally. Decks that cast Dimir Signet won 40% of those participations (12 wins in 30 games). Decks where the card never left the library won only 26.8% (26 wins in 97 games). The +13.2-point delta is in line with what two-mana ramp tends to produce. With 30 cast observations the finding is best treated as a strong early signal rather than a statistically settled conclusion.
What turn does Dimir Signet usually land on the battlefield? ▾
The median first-cast turn is 3, one turn behind its two-mana cost. The distribution shows 9 of 30 casts on turn 2 (exactly on curve), 2 casts on turn 1 via opening-hand acceleration, and the remainder spread across turns 4 through 10. The same-turn cast rate is 48%, meaning roughly half the time players hold it for at least one turn after drawing it before casting.
Which commanders most often run Dimir Signet in this dataset? ▾
Alela, Cunning Conqueror and Sauron, the Dark Lord each appear in 7 tracked decks that include Dimir Signet, the highest counts in the sample. Oloro, Ageless Ascetic and Phenax, God of Deception each show up in 6. The spread across multiple commander identities (straight Dimir, Grixis, and Esper) confirms the card earns its slot wherever blue and black mana are both needed in the early turns.
Is Dimir Signet legal in Commander? ▾
Yes, Dimir Signet is legal in Commander and has no restrictions there. It is also legal in Legacy, Modern, Vintage, Pauper, Pauper Commander, and several other formats. It is not legal in Standard, Pioneer, Alchemy, or Penny Dreadful.
Why include a two-mana Signet instead of a cheaper rock in Commander? ▾
Commander is a 40-life, multiplayer format where games regularly stretch into the mid and late turns. Two-mana fixing rocks like Dimir Signet cost one additional mana to activate, which is a real constraint, but they still accelerate your mana when cast on turn 2 off a land drop. The +13.2-point win-rate delta observed here reflects the broader Commander axiom: early ramp compounds throughout the game, and having the right colors on tap matters especially in two-color or three-color strategies.
