Emry, Lurker of the Loch + Displacer Kitten + Welding Jar + Sparring Mummy

Emry, Lurker of the Loch

Displacer Kitten

Welding Jar

Sparring Mummy

How it works

1. Activate Emry by tapping it, targeting Welding Jar.
2. Cast Welding Jar from your graveyard by paying 0.
3. Displacer Kitten triggers, blinking Sparring Mummy.
4. When Sparring Mummy enters, it triggers, untapping Emry.
5. Activate Welding Jar by sacrificing it.
6. Repeat.

This fascinating loop centers on Emry, Lurker of the Loch, who uses her tap ability to repeatedly pull Welding Jar from your graveyard for free. Each time you cast that artifact, Displacer Kitten's avoidance ability triggers to blink Sparring Mummy. As Sparring Mummy re-enters the battlefield, its triggered ability untaps Emry, preparing the merfolk wizard to tap and cast Welding Jar all over again.
