Emry, Lurker of the Loch + Mirran Spy + Welding Jar

Emry, Lurker of the Loch

Mirran Spy

Welding Jar

How it works

1. Activate Emry by tapping it, targeting Welding Jar.
2. Cast Welding Jar from your graveyard by paying 0.
3. Mirran Spy triggers, untapping Emry.
4. Activate Welding Jar by sacrificing it.
5. Repeat.

This ingenious loop hinges on Emry, Lurker of the Loch letting you repeatedly cast a cheap artifact right out of your graveyard, utilizing Welding Jar for its zero-mana cost so you never run out of resources. Every time you cast that artifact, Mirran Spy’s static ability triggers and untaps Emry, allowing you to tap her again and restart the cycle immediately. Since Welding Jar can conveniently sacrifice itself to its own regeneration ability, it smoothly generates infinite sacrifice triggers while maintaining the exact momentum needed to storm off.
