Emry, Lurker of the Loch + Displacer Kitten + Lion's Eye Diamond + Breaching Hippocamp

Emry, Lurker of the Loch

Displacer Kitten

Lion's Eye Diamond

Breaching Hippocamp

How it works

1. Activate Emry by tapping it, targeting Lion's Eye Diamond.
2. Cast Lion's Eye Diamond from your graveyard by paying 0.
3. Displacer Kitten triggers, blinking Breaching Hippocamp.
4. When Breaching Hippocamp enters, it triggers, untapping Emry.
5. Activate Lion's Eye Diamond by discarding your hand and sacrificing it.
6. Repeat.

This elegant loop relies on Emry, Lurker of the Loch to continually pull Lion's Eye Diamond back from your graveyard, turning the latter's high-risk sacrifice into a renewable mana source. Because Lion's Eye Diamond is an artifact, casting it triggers Displacer Kitten's avoidance ability to blink Breaching Hippocamp, clearing the way for the Hippocamp to untap Emry as it re-enters the battlefield. Every iteration of this cycle is fueled by the mana generated from Lion's Eye Diamond, allowing you to feed your storm count and cycle through your artifacts indefinitely.
