Nine Lives + Fractured Identity + Gideon of the Trials + Cleansing Nova

Nine Lives

Fractured Identity

Gideon of the Trials

Cleansing Nova

How it works

1. Cast Fractured Identity by paying 3, exiling Nine Lives and causing each opponent to create a token copy of it.
2. Nine Lives leaves the battlefield, however you cannot lose the game due to Gideon of the Trials.
3. Cast Cleansing Nova by paying its mana cost, destroying all enchantments.
4. When each opponent's Nine Lives leaves the battlefield, they each trigger, causing each opponent to lose the game.

This intricate locking mechanism centers around Gideon of the Trials, whose crucial emblem ensures that you simply cannot lose the game and your opponents cannot win. With that safety net established, you cast Fractured Identity to exile your own Nine Lives, generously handing your opponents token copies of the enchantment that normally spells doom when they leave the battlefield. Ordinarily, those tokens would mean your demise, but Gideon of the Trials protects you from that terrifying trigger entirely. Finally, you wipe the slate clean by casting Cleansing Nova to destroy all enchantments, forcing your opponents' copies of Nine Lives to leave the battlefield simultaneously and triggering their game-losing clauses to wipe out the table in one fell swoop.
