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

Ertha Jo, Frontier Mentor

Clock of Omens

Oreskos Sun Guide

Biotransference

How it works

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

This clever loop transforms a humble tap-ability into an engine of endless vitality. Biotransference does the heavy lifting behind the scenes by turning Oreskos Sun Guide into an artifact, allowing it to be legally targeted by Clock of Omens alongside the Clock itself. When you activate Clock of Omens by tapping both artifacts to untap Oreskos Sun Guide, Ertha Jo, Frontier Mentor steps in to double your efficiency, copying the ability so you can simultaneously untap the Clock itself. Every single cycle untaps Oreskos Sun Guide, triggering its inspired ability to net you infinite life without ever running out of untapped artifacts.
