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

Ertha Jo, Frontier Mentor

Clock of Omens

Sphinx's Disciple

Liquimetal Torque

How it works

1. Activate Liquimetal Torque by tapping it, 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 setup transforms a simple inspired mechanic into a self-sustaining engine by turning a creature into an artifact so it can fuel Clock of Omens directly. Liquimetal Torque handles that crucial type-changing role, allowing Sphinx's Disciple to be tapped alongside Clock of Omens to untap itself. The real magic, however, comes from Ertha Jo, Frontier Mentor, whose static ability catches you off guard by duplicating the Clock's activation whenever it targets a creature or player—or in this case, by letting the copied ability target the Clock itself. Every single iteration untaps both the Clock and Sphinx's Disciple, prompting the Disciple's inspired ability to trigger and draw you a card while resetting the loop for infinite card draw.
