Ertha Jo, Frontier Mentor + Clock of Omens + Memnarch

Ertha Jo, Frontier Mentor

Clock of Omens

Memnarch

How it works

1. Activate Memnarch by paying 1, 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 engine transforms any creature with a tap ability into a self-sustaining powerhouse with the help of Ertha Jo, Frontier Mentor, who acts as the magical fulcrum by doubling your targeted activated abilities. To make this work, Memnarch steps in to permanently paint any non-artifact creature with the artifact type, allowing it to seamlessly feed into Clock of Omens. By tapping the newly minted artifact creature alongside Clock of Omens to untap itself, you trigger Ertha Jo, Frontier Mentor to copy the untap ability, letting you untap both the clock and your creature to repeat the process indefinitely for infinite triggers.
