Ultimecia, Time Sorceress // Ultimecia, Omnipotent + Tetzin, Gnome Champion // The Golden-Gear Colossus + Conjurer's Closet + Encroaching Mycosynth

Ultimecia, Time Sorceress // Ultimecia, Omnipotent

Tetzin, Gnome Champion // The Golden-Gear Colossus

Conjurer's Closet

Encroaching Mycosynth

How it works

1. Declare The Golden-Gear Colossus as an attacker. It triggers, creating two 1/1 Gnome artifact creature tokens and transforming Ultimecia, Time Sorceress into Ultimecia, Omnipotent.
2. Ultimecia, Omnipotent triggers, causing you to take an extra turn after this one.
3. At the beginning of your end step, Conjurer's Closet triggers, blinking Ultimecia, Omnipotent. It'll enter the battlefield as Ultimecia, Time Sorceress.
4. When Ultimecia, Time Sorceress enters, it triggers, causing you to surveil 2.
5. Repeat each turn.

This clever setup turns time itself into an endless loop by uniting Encroaching Mycosynth with the engine pieces, ensuring everything on your battlefield counts as an artifact so Tetzin, Gnome Champion can recognize Ultimecia, Time Sorceress as a valid double-faced target. When The Golden-Gear Colossus attacks, it transforms Ultimecia into Ultimecia, Omnipotent to immediately claim an extra turn through Time Compression while spawning Gnomes. Finally, Conjurer's Closet steps in during your end step to blink the Omnipotent side back into the original Ultimecia, priming the board to repeat the cycle over and over again.
