This deliciously wicked sequence relies on turning your opponent's own resources against them by exploiting the fatal clause hidden within Immortal Coil. By casting Fractured Identity, you permanently exile your own Immortal Coil to strip it from your board and gift a token copy of it to each of your opponents instead. Because Immortal Coil's static text includes the grim rule that its controller loses the game when their graveyard is empty, you immediately drop the hammer by casting Mnemonic Betrayal. This sweeps away all cards from each opponent's graveyard, leaving them with zero cards in their yards while simultaneously controlling an Immortal Coil, instantly triggering its doomsday condition and eliminating them all in one fell swoop.
