Emry, Lurker of the Loch + Displacer Kitten + Urza's Bauble + The Fire Crystal

Emry, Lurker of the Loch

Displacer Kitten

Urza's Bauble

The Fire Crystal

How it works

1. Activate Emry by tapping it, allowing you to cast Urza's Bauble from your graveyard.
2. Cast Urza's Bauble by paying 0.
3. Displacer Kitten triggers, blinking Emry.
4. When Emry enters, it triggers, causing you to mill four cards.
5. Activate Urza's Bauble by tapping and sacrificing it.
6. Repeat.

This elegant loop turns a humble trinket into an engine of endless iteration by combining Emry, Lurker of the Loch with the repeatable card draw of Urza's Bauble. Every time you cast the zero-mana artifact from your graveyard using Emry's tap ability, Displacer Kitten steps in with its avoidance trigger to blink Emry away and right back onto the battlefield. This constant flickering refreshes Emry's tap ability while also dumping more options into your graveyard with each fresh enter-the-battlefield mill. While The Fire Crystal isn't strictly necessary for the core loop to spin, its cost reduction and haste-granting presence fit right into the artifact-heavy strategy.
