Lethal Scheme destroys a creature and gives connive counters to your attacking creatures — a combat trick, removal spell, and card selection stapled together for zero mana if you crew it with enough attackers. In Admiral Brass, Unsinkable builds, where you're already swinging with a board of pirates and want every attack to generate incremental value, this card does exactly what the deck is built to do.
Best Commanders
Commanders with the highest synergy
Admiral Brass, Unsinkable
Admiral Brass, Unsinkable decks attack with a wide pirate board every turn, meaning Lethal Scheme routinely costs nothing while simultaneously clearing a blocker and loading up creatures with +1/+1 counters that trigger Brass's reanimate ability.
Oskar, Rubbish Reclaimer
Lethal Scheme goes to the graveyard after resolving, which is exactly where Oskar, Rubbish Reclaimer wants noncreature spells — you cast it for free off attacking creatures, it cleans up a threat, and Oskar immediately recasts it from the bin.
Teval, the Balanced Scale
Teval, the Balanced Scale rewards you for putting counters on creatures and for filling your graveyard, and Lethal Scheme delivers both in a single free spell during your attack step.
Kamiz, Obscura Oculus
Kamiz, Obscura Oculus turns one unblocked attacker into a connive trigger every combat, and Lethal Scheme stacks additional connive on top of that while removing whatever was blocking your other creatures.
Caesar, Legion's Emperor
Caesar, Legion's Emperor wants as many attacking creatures as possible to maximize token production, and Lethal Scheme's convoke cost means a full board attack pays for the spell outright while keeping the combat math clean by eliminating a key blocker.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |

Commander is where Lethal Scheme belongs — convoke rewards wide creature boards, and multiplayer games consistently present high-value targets worth killing at instant speed during a combat step. In Legacy and Vintage it's legal but effectively irrelevant; those formats don't support the slow, creature-heavy board states convoke demands, and there are strictly more efficient removal options available. Lethal Scheme is legal in Oathbreaker, where the smaller starting life totals and focused synergy decks can make the connive upside meaningful, but its home remains Commander.
