Emry, Lurker of the Loch + Displacer Kitten + Welding Jar + The Fire Crystal

Emry, Lurker of the Loch

Displacer Kitten

Welding Jar

The Fire Crystal

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 ingenious loop turns a modest graveyard recursion engine into a self-sustaining machine by leveraging Displacer Kitten's blink trigger every time an artifact is recast. Because Welding Jar costs nothing to cast, it feeds the Kitten directly without draining your mana, allowing you to continually reset Emry, Lurker of the Loch as it enters and mills away your library. While Emry's affinity for artifacts and The Fire Crystal's cost reduction aren't strictly required to sustain this exact zero-mana loop, they make getting your pieces onto the battlefield and keeping your mana curve completely under control effortless.
