Ertha Jo, Frontier Mentor + Clock of Omens + Servant of Tymaret + Encroaching Mycosynth

Ertha Jo, Frontier Mentor

Clock of Omens

Servant of Tymaret

Encroaching Mycosynth

How it works

1. Activate Clock of Omens by tapping it and Servant of Tymaret, targeting Servant of Tymaret.
2. Ertha Jo triggers, copying Clock of Omens' ability, targeting Clock of Omens.
3. Resolve both Clock of Omens abilities, untapping it and Servant of Tymaret.
4. Servant of Tymaret triggers, causing each opponent to lose 1 life and you to gain that much life.
5. Repeat.

This intricate engine transforms your entire battlefield into a self-sustaining loop by letting Encroaching Mycosynth turn all nonland permanents into artifacts, making Servant of Tymaret an eligible target for Clock of Omens. When you tap Clock of Omens and the Servant to untap the Clock, Ertha Jo, Frontier Mentor steps in with her static ability to copy the activation because it targets a creature. As those abilities resolve, Servant of Tymaret untaps and triggers its inspired ability to drain your opponents while padding your life total, leaving both artifacts ready to repeat the process infinitely.
