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

Ertha Jo, Frontier Mentor

Clock of Omens

Siren of the Silent Song

Mycosynth Lattice

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 relies on Mycosynth Lattice to turn every permanent on the battlefield into an artifact, seamlessly pulling Siren of the Silent Song into a web of metal. You tap Siren of the Silent Song and Clock of Omens to pay the Clock's activation cost, targeting the Siren herself to untap her. Because the targeted Siren of the Silent Song is an activated ability targeting a permanent you control, Ertha Jo, Frontier Mentor swoops in to copy the ability, allowing you to untap Clock of Omens as well. As Siren of the Silent Song becomes untapped, its inspired ability triggers to drain your opponents' resources through endless discarding and milling.
