Ertha Jo, Frontier Mentor + Clock of Omens + Servant of Tymaret + Biotransference

Ertha Jo, Frontier Mentor

Clock of Omens

Servant of Tymaret

Biotransference

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 crafty loop turns your own board into a self-sustaining engine by making every activation double up. Biotransference is the foundation of this setup, turning Servant of Tymaret into an artifact so it can be targeted by Clock of Omens alongside itself. When you activate Clock of Omens using those two artifacts to untap Servant of Tymaret, Ertha Jo, Frontier Mentor steps in to copy that targeting ability—allowing you to untap Clock of Omens in the process. As Servant of Tymaret becomes untapped, its inspired ability triggers to drain your opponents dry while padding your life total, leaving you free to repeat the entire sequence indefinitely.
