Grand Larceny is a Sultai (blue-black-green) Commander deck that turns combat damage into stolen options, led by Gonti, Canny Acquisitor. By rewarding any creature that connects, Gonti fuels a steady stream of face-down exiles from opponents’ libraries, then discounts those pilfered spells and lets you cast them with mana of any type. Cheap evasive bodies like Slither Blade and Triton Shorestalker get the engine online early, while cards such as Thief of Sanity, Fallen Shinobi, and Nashi, Moon Sage’s Scion multiply the theft into real card advantage. Games play at a midrange pace with a proactive, interactive feel: you pressure life totals through repeated chip damage while disrupting boards with Putrefy, Feed the Swarm, Baleful Mastery, and sweepers like Curse of the Swine. The closing path often comes from overwhelming value—casting opponents’ best haymakers, scaling threats like Villainous Wealth, or sticking a powerful top-end such as Mind’s Dilation or Diluvian Primordial. Players who enjoy opportunistic lines and adapting to the table will find it rewarding, and upgrades naturally lean toward more evasive attackers, extra combat steps, and tighter protection for Gonti.
