Mycosynth Lattice turns every permanent on the board into an artifact, and that single line of text warps the game around it — every Karn, the Great Creator on the table now locks opponents out of their entire mana base, and Memnarch can steal any permanent for two blue mana. Six mana is a real cost, but the effect is so warping that the card pays for itself the moment it resolves.

Format Analysis

Where it lives, where it can’t

Format	Verdict
commander	legal
legacy	legal
modern	banned
pioneer	not legal
standard	not legal
vintage	legal
pauper	not legal
oathbreaker	legal

Mycosynth Lattice is banned in Modern, where the Karn, the Great Creator lock is too consistent and too fast to disrupt in a 60-card format with robust tutors and redundancy. Legacy and Vintage allow it but the slower metagames and access to Force of Will keep it from dominating. Commander is where Mycosynth Lattice truly lives — the six-mana cost is far more manageable in a 40-life multiplayer game, and the political chaos of making everyone's permanents artifacts means the threat is distributed across the table, softening the case for any one player to immediately answer it.

Best Commanders

Commanders with the highest synergy

Memnarch

66.2% of decks · synergy 0.63

Memnarch's activated ability already targets artifacts, so Mycosynth Lattice converts every land, creature, and enchantment opponents control into a valid theft target — the two-card engine lets Memnarch take the entire board for two blue mana per permanent.

Chiss-Goria, Forge Tyrant

36.2% of decks · synergy 0.34

Chiss-Goria, Forge Tyrant's affinity-for-artifacts cost reduction and triggered ability both scale directly with artifact count, and Mycosynth Lattice makes every nonland permanent count toward that density, dramatically accelerating when Chiss-Goria can swing for free.

Knuckles the Echidna

35.7% of decks · synergy 0.33

Knuckles the Echidna cares about artifacts entering the battlefield and benefiting from artifact synergies, so Mycosynth Lattice inflates the artifact count across the whole board, fueling Knuckles' triggers and turning opposing permanents into resources.

Daretti, Scrap Savant

35.1% of decks · synergy 0.32

Daretti, Scrap Savant's reanimation and looting lines want a board saturated with artifacts, and Mycosynth Lattice ensures that any permanent hitting the graveyard or battlefield qualifies — it also enables degenerate recursion loops with Daretti's ultimate.

Arcum Dagsson

32.8% of decks · synergy 0.30

Arcum Dagsson can only tutor by sacrificing artifact creatures, and Mycosynth Lattice converts every creature on the board — including opponents' — into a valid sacrifice target, turning Dagsson into an unrestricted tutor engine.

Price Context

Current price

unknown tier

Mycosynth Lattice has historically floated in the $20–40 range depending on print run, with reprints periodically pushing it toward the lower end. It's a card worth picking up when it's in print — the demand from artifact commanders is consistent enough that copies don't stay cheap for long after supply dries up.
