Ultimecia, Time Sorceress // Ultimecia, Omnipotent + Tetzin, Gnome Champion // The Golden-Gear Colossus + Liquimetal Coating + Airbender Ascension

Ultimecia, Time Sorceress // Ultimecia, Omnipotent

Tetzin, Gnome Champion // The Golden-Gear Colossus

Liquimetal Coating

Airbender Ascension

How it works

1. Activate Liquimetal Coating by tapping it, causing Ultimecia, Time Sorceress to become an artifact.
2. 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.
3. Ultimecia, Omnipotent triggers, causing you to take an extra turn after this one.
4. At the beginning of your end step, Airbender Ascension triggers, blinking Ultimecia, Omnipotent. It'll enter the battlefield as Ultimecia, Time Sorceress.
5. When Ultimecia, Time Sorceress enters, it triggers, causing you to surveil 2.
6. Repeat each turn.
