Ertha Jo, Frontier Mentor + Clock of Omens + Siren of the Silent Song + Encroaching Mycosynth

Ertha Jo, Frontier Mentor

Clock of Omens

Siren of the Silent Song

Encroaching Mycosynth

How it works

1. Activate Clock of Omens by tapping it and Siren of the Silent Song, targeting Siren of the Silent Song.
2. Ertha Jo triggers, copying Clock of Omens' ability, targeting Clock of Omens.
3. Resolve both Clock of Omens abilities, untapping it and Siren of the Silent Song.
4. Siren of the Silent Song triggers, causing each opponent to discard and mill a card.
5. Repeat.

This clever loop transforms an ordinary artifact-untapping engine into a devastating discard and mill machine by leveraging **Encroaching Mycosynth** to turn your entire board into artifacts, ensuring that **Clock of Omens** can readily target **Siren of the Silent Song** using itself and any other permanent as the cost. As **Siren of the Silent Song** becomes untapped via this process, its inspired ability naturally triggers to drain your opponents' resources. However, the true alchemy of the combo lies in **Ertha Jo, Frontier Mentor**, whose static ability doubles the **Clock of Omens** activation by copying it whenever it targets a permanent, allowing a single activation to untap both the clock and the Siren simultaneously and perpetuate the loop indefinitely.
