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

Ultimecia, Time Sorceress // Ultimecia, Omnipotent

Tetzin, Gnome Champion // The Golden-Gear Colossus

Biotransference

Conjurer's Closet

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 brilliant loop takes advantage of Biotransference turning every creature spell and card you own into an artifact, allowing Tetzin, Gnome Champion to trigger its milling and retrieval abilities off your creature drops. Once Tetzin is crafted into The Golden-Gear Colossus, its attack trigger transforms Ultimecia, Time Sorceress into Ultimecia, Omnipotent to instantly secure an extra turn via Time Compression. Finally, Conjurer's Closet effortlessly resets Ultimecia back to her front face at the end step, setting up the entire cycle to repeat anew on every single extra turn.
