3% of tracked Commander decks run Worn Powerstone. When drawn, 79% of copies reach the battlefield, with a median first-cast turn of 4.0.

Worn Powerstone is a colorless mana rock that fits into any Commander deck, appearing in 353 of the 12310 distinct decks tracked on Playgroup Live. Its 3% inclusion rate reflects a niche but consistent role: a {3}-mana artifact that taps for two colorless, primarily serving high-cost commanders that need ramp to hit the board quickly.

The draw-to-play rate sits at 79%, meaning most drawn copies do get cast before the game ends. The median first cast lands on turn 4.0, which is a turn late relative to Worn Powerstone's own mana value of 3. That gap is typical for singleton ramp pieces that often arrive after the opening hand, rather than a signal that players are choosing to hold it.

The cast-vs-library win-rate delta is effectively flat at this sample size, so there is no directional signal here that resolving Worn Powerstone independently predicts a win. Its value is structural: doubling mana output from a single artifact slot to fuel larger spells later in the game. The top commanders pairing with it skew heavily toward colorless and high-CMC strategies, consistent with that role.

≥ -7.8pp

Players who cast this card win 22% of the time (n=111) , vs 22% when it never left the library (n=380).

When players drew this card but left it in hand, they won 27% (n=27) — 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 +0.2pp; 95% confidence interval -7.8pp to +8.2pp. Correlational, not causal: powerful payoffs also get cast more often in games you are already winning.

Frequently Asked

How often is Worn Powerstone drawn in a Commander game?
Across 578 tracked games where Worn Powerstone was in a deck, it was drawn 24% of the time. That is a typical draw rate for a singleton in a 100-card deck. Of 142 instances that reached a player's hand, 79% were cast before the game ended.
What turn does Worn Powerstone usually get cast?
The median first-cast turn is 4.0, with a mean of about 5.15. The card's mana value is 3, so most casts land on or after curve rather than ahead of it. The on-curve rate is 39%, and the majority of casts fall behind curve, which is consistent with a card that players draw mid-game rather than in their opening hand.
Does casting Worn Powerstone improve your chances of winning?
In 111 participations where Worn Powerstone was cast, the normalized win rate is 22%. Participations where it never left the library show 22%. The delta between those two figures is very small and the confidence interval crosses zero at this sample size, so treat any apparent lift as directional only. The data does not yet support a stronger claim.
Is Worn Powerstone legal in Commander?
Yes. Worn Powerstone is legal in Commander, Duel Commander, Oathbreaker, Brawl, Legacy, Modern, Vintage, Historic, Timeless, and several other formats. It is not legal in Standard, Pioneer, Pauper, or Pauper Commander.
Which commanders pair most often with Worn Powerstone?
Sauron, Lord of the Rings leads the list with 353 total tracked decks for the card, and colorless or high-CMC commanders like Zhulodok, Void Gorger and Kozilek, the Great Distortion also appear near the top. The concentration data is healthy: 299 distinct players have brought Worn Powerstone to tracked games, and no single player accounts for more than a small fraction of the data.
How well does Worn Powerstone stick on the battlefield?
Battlefield stickiness, the share of cast copies that are still in play at the end of the game, is 84%. Artifacts in Commander face removal less reliably than creatures, and a mana rock that immediately enters tapped is a lower-priority target, which likely contributes to that figure. Graveyard and exile counts make up most of the non-battlefield final zones.
