Emry, Lurker of the Loch + Displacer Kitten + Welding Jar + Garna, the Bloodflame

Emry, Lurker of the Loch

Displacer Kitten

Welding Jar

Garna, the Bloodflame

How it works

1. Activate Emry by tapping it, allowing you to cast Welding Jar from your graveyard.
2. Cast Welding Jar by paying 0.
3. Displacer Kitten triggers, blinking Emry.
4. When Emry enters, it triggers, causing you to mill four cards.
5. Activate Welding Jar by sacrificing it.
6. Repeat.

This loop turns the recursive nature of Emry, Lurker of the Loch into a self-sustaining engine by utilizing Welding Jar as a zero-mana catalyst. Each time you cast the Jar from your graveyard using Emry's tap ability, Displacer Kitten's avoidance trigger blinks Emry away and brings it right back, resetting its tap ability and milling four more cards in the process. Because Welding Jar can immediately sacrifice itself to protect another artifact or just cycle through the loop, you can repeat this sequence indefinitely. Meanwhile, Garna, the Bloodflame sits in reserve to grant haste or recursion if needed, completing an elegant battlefield puzzle that churns through your entire deck.
