Activate Emry by tapping it, allowing you to cast Welding Jar from your graveyard.
Cast Welding Jar by paying 0.
Displacer Kitten triggers, blinking Emry.
When Emry enters, it triggers, causing you to mill four cards.
Activate Welding Jar by sacrificing it.
Repeat.
This clever loop relies on Emry, Lurker of the Loch to constantly pull Welding Jar back from the graveyard, exploiting its zero-mana cost to keep the chain moving. Every time you cast that artifact, Displacer Kitten steps in with its blink ability to reset Emry, allowing you to repeat the process indefinitely while milling your library away piece by piece. Meanwhile, Anger quietly sits in the graveyard, granting your entire team haste as long as you control a Mountain, turning this engine into an explosive setup for whatever you dredge up next.
