Ertha Jo, Frontier Mentor + Clock of Omens + King Macar, the Gold-Cursed + Mycosynth Lattice

Ertha Jo, Frontier Mentor

Clock of Omens

King Macar, the Gold-Cursed

Mycosynth Lattice

How it works

1. Activate Clock of Omens by tapping it and King Macar, targeting King Macar.
2. Ertha Jo triggers, copying Clock of Omens' ability, targeting Clock of Omens.
3. Resolve both Clock of Omens abilities, untapping it and King Macar.
4. King Macar triggers, exiling target creature and creating a Gold token.
5. Repeat.

This ingenious loop turns King Macar, the Gold-Cursed into an absolute menace by leveraging Mycosynth Lattice to turn every permanent on the battlefield into an artifact, allowing Clock of Omens to constantly untap King Macar alongside itself. As this engine spins, the unassuming Ertha Jo, Frontier Mentor acts as a brilliant force multiplier; because King Macar's inspired untap is an ability triggered by becoming untapped, Ertha Jo's presence enables profound synergy, though the core of the loop is the artifact-untap dance. By repeatedly untapping King Macar, you systematically exile every creature your opponents control while generating a near-infinite supply of Gold tokens to fuel future turns.
