Emry, Lurker of the Loch + Displacer Kitten + Welding Jar + Frostcliff Siege

Emry, Lurker of the Loch

Displacer Kitten

Welding Jar

Frostcliff Siege

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 puts Emry, Lurker of the Loch into constant motion by leveraging the zero-mana casting cost of Welding Jar, which can be repeatedly pulled back from the graveyard using Emry's tap ability. Every time you cast the Jar, Displacer Kitten triggers its avoidance ability to blink Emry, resetting her tap ability and triggering a fresh mill of four cards upon her return. Meanwhile, Frostcliff Siege sits quietly on the battlefield, providing its chosen enchantment bonuses while this self-sustaining cycle generates an endless stream of artifact entries, leaves, and sacrifices.
