Chasm Skulker appears in 5% of tracked multiplayer Commander decks on Playgroup Live, drawn 31% of the time and cast on a median turn of 6, with 318 distinct players bringing it to a tracked game.

Chasm Skulker is a blue draw-payoff creature that grows on every card drawn and floods the board with islandwalk Squid tokens when it dies. Across Playgroup Live's tracked multiplayer Commander games, it sits in 5% of observed decks, spread across 318 distinct players. No single player dominates the sample: the heaviest contributor accounts for just 3% of all tracked instances, a healthy spread that gives the numbers real breadth.

The card's play pattern is deliberate. Players hold it a median of one turn after drawing before casting it, and only 28% of drawn copies are slammed onto the table the same turn they arrive. The median first cast lands on turn 6, well past its 3-mana cost, which reflects both the draw-heavy decks that run it and the strategic patience required to grow its counter stack before the inevitable removal comes. 50% of resolved Chasm Skulkers survive through the end of the game, a middling stickiness figure that captures how often it trades into removal before the tokens ever materialize.

The commander distribution tells a clear story: draw-synergy commanders dominate the list. Ms. Bumbleflower, Tidus, and Xyris all want to generate card draw at scale, which is exactly the environment where Chasm Skulker snowballs fastest. Its blue-only color identity keeps it out of non-blue pods entirely, so the 5% figure understates its penetration within eligible decks.

Of 676 Chasm Skulkers brought to tracked games, 208 were drawn, 129 of those reached the battlefield, and 50% survived through end of game. A meaningful slice ends in the graveyard mid-game, often converting into the token flood the card promises.

≥ -1.2pp

Players who cast this card win 29% of the time (n=121) , vs 22% when it never left the library (n=409).

When players drew this card but left it in hand, they won 33% (n=73) — 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 +7.1pp; 95% confidence interval -1.2pp to +15.5pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.

Most undrawn Chasm Skulkers never leave the library, a structural reality of 100-card singleton. Of observed copies, the split between battlefield survivors and graveyard finishes reflects how often removal trades with the Skulker before its death trigger can convert counters into a Squid army.

Commanders that played this card

in tracked games

Draw-synergy commanders dominate the list: Ms. Bumbleflower, Tidus, and Xyris all generate card draw at scale, giving Chasm Skulker a reliable engine to stack counters. The spread across multiple archetypes shows it is not a one-deck card.

Frequently Asked

How often is Chasm Skulker drawn in a Commander game?
In 652 tracked multiplayer games where Chasm Skulker was in the deck, it was drawn 31% of the time. That draw rate is modestly above average for a singleton in a 100-card deck, which makes sense: many of the decks running it are draw-heavy builds that cycle through their library faster than typical pods. Of 208 total instances that reached a player's hand, 62% were eventually cast.
What turn does Chasm Skulker usually get cast?
Median first cast is turn 6, with the distribution running from turn 1 (a rare ramp-assisted opening) through turn 11. The most common single cast turn is turn 3, right on curve, but the long tail of mid-game casts pulls the median to turn 5. Only 25% of casts land exactly on curve at turn 3. Players tend to hold it about one turn after drawing before committing it to the board: the median hand-to-cast delay is 1 turn, and just 28% of drawn copies are cast immediately.
Does casting Chasm Skulker actually improve your win rate?
The cast win rate is 29% across 121 observations, compared to 22% when it stayed in the library. That's a +7.1 percentage-point gap in favor of casting. However, the standard error on this dataset means the gap is directional rather than statistically confirmed. Early signal suggests casting it correlates with better outcomes, but treat it as a trend rather than a proven lift.
Is Chasm Skulker banned in any format?
Chasm Skulker is legal in Commander, Legacy, Modern, Pioneer, Vintage, Historic, and several other formats. It is not legal in Standard, Pauper, or Pauper Commander. There are no bans in the formats where it is legal, so it is freely available for Commander pods without restriction.
Which commanders run Chasm Skulker most often?
Ms. Bumbleflower and Tidus, Yuna's Guardian lead the tracked data, both in the Bant (G/U/W) color identity with strong group-draw mechanics. Captain N'ghathrod and Xyris, the Writhing Storm also appear near the top, representing blue-black mill and blue-red-green wheel strategies respectively. The common thread is commanders that generate card draw at scale, giving Chasm Skulker the fuel it needs to stack counters quickly and become a serious threat or a punishing death trigger.
How spread is the Chasm Skulker data across players?
The data comes from 318 distinct players, and the single heaviest contributor accounts for just 3% of all tracked instances. That concentration figure is well below 15%, which is a positive signal for data quality. The numbers here reflect a broad cross-section of the Playgroup Live community rather than one player's dedicated testing, though the total dataset of 652 tracked games is still modest enough to treat every trend as directional.
