Orvar, the All-Form + Whim of Volrath + Coveted Jewel

Orvar, the All-Form

Whim of Volrath

Coveted Jewel

How it works

1. Activate Coveted Jewel by tapping it, adding .
2. Cast Whim of Volrath with buyback by paying 2, targeting Coveted Jewel.
3. Orvar's first ability triggers, creating a token copy of Coveted Jewel.
4. When the copy of Coveted Jewel enters the battlefield, it triggers, causing you to draw three cards.
5. Resolve Whim of Volrath, returning it to your hand.
6. Repeat.

This clever loop turns Coveted Jewel into a self-sustaining engine by tapping it for three mana to pay the exact cost of casting Whim of Volrath with buyback. Every time you cast Whim of Volrath targeting the original artifact, Orvar, the All-Form notices the spell targeting a permanent you control and steps in to create a brand new token copy. That fresh token immediately triggers Coveted Jewel's enter-the-battlefield ability to draw you three cards, letting you churn through your entire deck while generating an endless army of jewels.
