Strength-Testing Hammer
Artifact — Equipment
Whenever equipped creature attacks, roll a six-sided die. That creature gets +X/+0 until end of turn, where X is the result. Then if it has the greatest power or is tied for greatest power among creatures on the battlefield, draw a card.

Strength-Testing Hammer puts a free dice roll on every attacking creature and cashes those rolls into counters or card advantage — the on-board value accrues fast. The cost is deckbuilding commitment: you need a commander like Wyll, Blade of Frontiers // Sword Coast Sailor who actually does something with those dice results, or the Hammer is just a slow enchantment.
Best Commanders
Commanders with the highest synergy
Wyll, Blade of Frontiers // Sword Coast Sailor
Wyll, Blade of Frontiers // Sword Coast Sailor triggers on every die roll, so Strength-Testing Hammer turning each attack step into a dice-rolling event compounds his +1/+1 counter generation and card advantage at a rate few artifacts can match — this is the deck where the Hammer is an auto-include.
The Most Dangerous Gamer
The Most Dangerous Gamer cares about rolling high, and Strength-Testing Hammer puts dice rolls on every attacking creature, dramatically increasing the frequency of high-value results that trigger his hunt mechanic.
Slicer, Hired Muscle
Slicer, Hired Muscle attacks every turn as a matter of course, so Strength-Testing Hammer slots in as a repeatable dice engine that generates counters or value without any extra investment — the aggro-facing gameplan and the Hammer's combat trigger line up cleanly.
Mr. House, President and CEO
Mr. House, President and CEO converts dice rolls directly into Servo tokens, and Strength-Testing Hammer attaches a free roll to every attacking creature, turning a wide board into a Servo factory each combat.
Alexios, Deimos of Kosmos
Alexios, Deimos of Kosmos scales on +1/+1 counters, and Strength-Testing Hammer's dice rolls are a consistent source of them — lower synergy than the dedicated dice commanders, but still a reliable counter engine in his 99.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |

| oathbreaker | legal |
Strength-Testing Hammer is a Commander card through and through — the dice-rolling payoff structure is slow and cumulative, which fits a 100-card singleton format with longer games and dedicated commanders that double-dip on every roll. In Vintage and Legacy it's legal but irrelevant; those formats end before the Hammer generates meaningful value, and neither has the commander-centric synergy density that makes it tick. Oathbreaker is a workable home if your planeswalker cares about dice or counters, but the card pool is narrower and the games shorter, so it lands as a fringe inclusion there rather than a staple.
