Nine Lives + Fractured Identity + Gideon of the Trials + Austere Command
Nine Lives
Fractured Identity
Gideon of the Trials
Austere Command
Each opponent loses the game
How it works
Cast Fractured Identity by paying 3, exiling Nine Lives and causing each opponent to create a token copy of it.
Nine Lives leaves the battlefield, however you cannot lose the game due to Gideon of the Trials.
Cast Austere Command by paying its mana cost, destroying all enchantments.
When each opponent's Nine Lives leaves the battlefield, they each trigger, causing each opponent to lose the game.
This clever lock relies on Gideon of the Trials and his emblem to completely rewrite the rules of survival, ensuring that the usual punishment for losing Nine Lives cannot touch you. By casting Fractured Identity targeting your own Nine Lives, you hand a copy of the enchantment to every single opponent while sending yours away safely. Once you wipe the board clean with Austere Command to destroy all enchantments at once, every opponent's copied Nine Lives triggers its delayed clause, forcing them all to lose the game simultaneously.
