Ertha Jo, Frontier Mentor + Clock of Omens + Oreskos Sun Guide + Memnarch

Ertha Jo, Frontier Mentor

Clock of Omens

Oreskos Sun Guide

Memnarch

How it works

1. Activate Memnarch by paying 1, causing Oreskos Sun Guide to become an artifact.
2. Activate Clock of Omens by tapping it and Oreskos Sun Guide, targeting Oreskos Sun Guide.
3. Ertha Jo triggers, copying Clock of Omens' ability, targeting Clock of Omens.
4. Resolve both Clock of Omens abilities, untapping it and Oreskos Sun Guide.
5. Oreskos Sun Guide triggers, causing you to gain 2 life.
6. Repeat from step 2.

This clever loop turns an ordinary citizen into an artifact and uses her innate talent to multiply mechanical leverage. Memnarch does the heavy lifting up front by making Oreskos Sun Guide an artifact, allowing it to serve as the tap-target for Clock of Omens alongside the Clock itself. When you activate Clock of Omens by tapping both artifacts, Ertha Jo, Frontier Mentor spots the targeting requirement and instantly copies the ability, letting you untap both the Clock and Oreskos Sun Guide simultaneously. As Oreskos Sun Guide becomes untapping, its inspired ability triggers to reward you with life, and because Clock of Omens is also untapping, the entire sequence can be repeated indefinitely for boundless life.
