Ertha Jo, Frontier Mentor + Clock of Omens + Sphinx's Disciple + Memnarch

Ertha Jo, Frontier Mentor

Clock of Omens

Sphinx's Disciple

Memnarch

How it works

1. Activate Memnarch by paying 1, causing Sphinx's Disciple to become an artifact.
2. Activate Clock of Omens by tapping it and Sphinx's Disciple, targeting Sphinx's Disciple.
3. Ertha Jo triggers, copying Clock of Omens' ability, targeting Clock of Omens.
4. Resolve both Clock of Omens abilities, untapping it and Sphinx's Disciple.
5. Sphinx's Disciple triggers, causing you to draw a card.
6. Repeat from step 2.

This clever loop turns Clock of Omens into a self-sustaining engine by transforming Sphinx's Disciple into an artifact using Memnarch's first ability. When you tap the Disciple and the Clock to pay the Clock's cost, Ertha Jo, Frontier Mentor steps in to double the fun by copying the activation, allowing you to untap both artifacts simultaneously. Every single time the Disciple untaps, its inspired ability triggers to draw you a card, feeding you your entire deck one loop at a time.
