Trove of Temptation

Trove of Temptation is a Commander card through and through — the political tension of forced attacks and the incremental artifact generation both scale with the multiplayer environment in ways that never translate to one-on-one. In Legacy, Modern, or Vintage, a four-mana enchantment that hands your opponent a free attacker every turn is simply giving away the game; those formats will never touch it competitively. Commander is the only context where the forced-attack clause can be pointed at an opponent across the table while a third player benefits, and where a Treasure token per upkeep compounds into something meaningful over a long game.
