Drafna, Founder of Lat-Nam + Manifold Key + Coveted Jewel + Semblance Anvil

Drafna, Founder of Lat-Nam

Manifold Key

Coveted Jewel

Semblance Anvil

How it works

1. Activate Coveted Jewel by tapping it, adding .
2. Activate Manifold Key by paying 1 and tapping it, untapping Coveted Jewel.
3. Activate Drafna's first ability by paying 1, returning Manifold Key from the battlefield to your hand.
4. Cast Manifold Key by paying 0.
5. Repeat.

This clever loop turns Coveted Jewel into a self-sustaining engine by leveraging cost reduction and active utility. With Semblance Anvil already having exiled a nonland card to make artifact spells cost {2} less, Manifold Key can be cast for free after every bounce. You tap Coveted Jewel for a hefty mana injection, use Manifold Key to untap the Jewel, and then let Drafna, Founder of Lat-Nam pick up the Manifold Key so you can recast it for zero mana. Repeating this cycle yields an endless stream of artifact enters-the-battlefield triggers, draws your entire deck through the Jewel, and builds a massive storm count.
