Worn Powerstone card art
Worn Powerstone enters tapped, which is the real cost — you invest mana now and wait a turn to see returns, making it a poor fit for fast, interactive decks that need mana on curve. Where it earns its slot is in high-CMC shells: Sauron, Lord of the Rings decks lean on it to hit the mana thresholds that make their Amass payoffs and token engines pop off, and fringe combo builds use it as an imprint target for Myr Welder to generate floating mana in unexpected ways.

Best Commanders

Commanders with the highest synergy

01
Sauron, Lord of the Rings

Sauron, Lord of the Rings

54.0% of decks · synergy 0.49

Sauron, Lord of the Rings demands a lot of mana early and often — Worn Powerstone helps bridge the gap between casting Sauron and immediately threatening the table with Amass triggers and Army-pumping spells on the same turn.

02
Ovika, Enigma Goliath

Ovika, Enigma Goliath

32.9% of decks · synergy 0.29

Ovika, Enigma Goliath rewards you for casting noncreature spells, and the extra two colorless mana from Worn Powerstone lets you chain spells on a single turn rather than spreading them across multiple turns, multiplying the Goblin token output.

03
Kozilek, the Great Distortion

Kozilek, the Great Distortion

75.8% of decks · synergy 0.24

Kozilek, the Great Distortion costs ten mana — Worn Powerstone appears in over 75% of Kozilek lists because every rock that produces two or more mana meaningfully accelerates the turn you slam the commander and refill your hand.

04
Etali, Primal Storm

Etali, Primal Storm

28.0% of decks · synergy 0.23

Etali, Primal Storm wants to attack as early as possible, and the colorless ramp from Worn Powerstone helps push a seven-drop commander out ahead of curve so it can start stealing spells before opponents stabilize.

05
Memnarch

Memnarch

28.2% of decks · synergy 0.23

Memnarch's activated ability is mana-hungry by design, and Worn Powerstone feeds that engine directly — each activation to steal a permanent becomes cheaper to sequence when you have a dedicated two-mana rock sitting in play.

Format Analysis

Where it lives, where it can’t

FormatVerdict
commander legal
legacy legal
modern legal
pioneer not legal
standard not legal
vintage legal
pauper not legal
oathbreaker legal

Worn Powerstone is a Commander card through and through — the format's slower pace and high-CMC commanders make a tapped two-mana rock acceptable in a way that 60-card formats simply don't allow. In Legacy and Vintage, where games end before the rock even untaps, it sees essentially zero competitive play; better fast mana exists at every price point in those formats. Modern is legal but irrelevant for the same reason: the tempo loss of entering tapped is disqualifying in any realistic Modern shell. Commander is where Worn Powerstone actually functions — specifically in colorless or artifact-heavy decks that need non-green ramp and don't care about the one-turn delay because their game plan operates on turns five through nine anyway.

Price Context

Current price

$0.45 bulk tier

At $0.45, Worn Powerstone is firmly bulk — it has been reprinted enough times that copies are abundant and the price floor is unlikely to move in either direction. For the mana it produces, it's a low-risk inclusion in any Commander deck that wants cheap artifact ramp and isn't sensitive to the enters-tapped drawback.
