Ertha Jo, Frontier Mentor + Clock of Omens + Pheres-Band Tromper + Biotransference

Ertha Jo, Frontier Mentor

Clock of Omens

Pheres-Band Tromper

Biotransference

How it works

1. Activate Clock of Omens by tapping it and Pheres-Band Tromper, targeting Pheres-Band Tromper.
2. Ertha Jo triggers, copying Clock of Omens' ability, targeting Clock of Omens.
3. Resolve both Clock of Omens abilities, untapping it and Pheres-Band Tromper.
4. Pheres-Band Tromper triggers, putting a +1/+1 counter on it.
5. Repeat

This clever loop relies on turning your creatures into artifacts using Biotransference, allowing Pheres-Band Tromper to pull double duty as both a participant in your artifact synergies and the creature that reaps the rewards of its own untapping. By tapping both Clock of Omens and the Tromper itself, you trigger Clock of Omens' untap ability; because this activation targets a permanent, Ertha Jo, Frontier Mentor steps in to copy it, letting you untap both the Clock and the Tromper simultaneously. Every single time the Tromper untaps this way, its inspired ability triggers to stack another +1/+1 counter on it, creating an endlessly growing threat while keeping your untap engine running at full speed.
