Artifact — Equipment
Equipped creature gets +3/+2.

Buster Sword lands on the battlefield and immediately threatens to end games — the +4/+4 and double strike it grants can turn any sufficiently large creature into a one-hit closer. The cost is real: five mana to equip is punishing outside of Cloud, Midgar Mercenary, who can cheat that number down dramatically.
Best Commanders
Commanders with the highest synergy
Cloud, Midgar Mercenary
Buster Sword is the premier target for Cloud, Midgar Mercenary — his ability to reduce equip costs means the sword comes online turn after turn without hemorrhaging mana, and the double strike it provides doubles every trigger Cloud generates on combat damage.
Noctis, Heir Apparent
Noctis, Heir Apparent tutors for legendary weapons, making Buster Sword a reliable line rather than a lucky draw, and the double strike pairs with Noctis's own combat-damage payoffs to close games fast.
Cloud, Ex-SOLDIER
Cloud, Ex-SOLDIER wants the biggest, most threatening weapon available, and Buster Sword delivers — the +4/+4 pushes Cloud into one-shot range while double strike ensures every combat step counts.
Gilgamesh, Master-at-Arms
Gilgamesh, Master-at-Arms collects legendary equipment as a core strategy, and Buster Sword is one of the highest-impact additions to that pile — the offensive boost it provides makes Gilgamesh a credible threat rather than a slow value engine.
Jin Sakai, Ghost of Tsushima
Jin Sakai, Ghost of Tsushima rewards repeated, evasive attacks, and Buster Sword's double strike means every hit from Jin counts twice — pairing naturally with his token and combat-damage triggers for accelerating board dominance.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |
|---|---|
| commander | legal |
| legacy | legal |
| modern | legal |
| pioneer | legal |
| standard | legal |
| vintage | legal |
| pauper | not legal |
| oathbreaker | legal |
Buster Sword is legal across every major Constructed format except Pauper, but Commander is by far its natural home — the singleton environment means you only need one copy, and the legendary Equipment type slots cleanly into any equipment-matters or Voltron strategy. In 60-card formats like Modern and Pioneer, five mana to equip is simply too slow without dedicated cost-reduction, and the lack of an attached creature means you're spending resources to set up a threat rather than being one. Standard gives it the most competitive footing outside of Commander, where the power level is lower and a double-strike threat can end games before opponents stabilize. Treat Buster Sword as a Commander card that happens to be legal elsewhere.
