Ertha Jo, Frontier Mentor + Clock of Omens + Liquimetal Coating

Ertha Jo, Frontier Mentor

Clock of Omens

Liquimetal Coating

How it works

1. Activate Liquimetal Coating by tapping it, giving the creature with a tap trigger the artifact type.
2. Activate Clock of Omens by tapping it and the creature with a tap trigger, targeting the creature.
3. Ertha Jo and the creature trigger.
4. Resolve the creature's trigger.
5. Resolve the Ertha Jo trigger, copying Clock of Omens' ability, targeting Clock of Omens.
6. Resolve both Clock of Omens abilities, untapping it and the creature tapped in step 2.
7. Repeat from step 2.

This clever setup transforms any creature with a tap-activated ability into an infinite engine by leveraging Liquimetal Coating to turn that creature into an artifact. Once qualified, the creature joins forces with Clock of Omens to constantly untap itself, while Ertha Jo, Frontier Mentor watches the proceedings and eagerly doubles every single targeted ability you activate. The result is a self-sustaining loop that generates infinite triggers from your chosen creature, perfect for dominating the Commander, Legacy, Modern, Oathbreaker, and Vintage formats.
