Emry, Lurker of the Loch + Displacer Kitten + Hyrax Tower Scout + Dark Sphere

Emry, Lurker of the Loch

Displacer Kitten

Hyrax Tower Scout

Dark Sphere

How it works

1. Activate Emry by tapping it, targeting Dark Sphere.
2. Cast Dark Sphere from your graveyard by paying 0.
3. Displacer Kitten triggers, blinking Hyrax Tower Scout.
4. When Hyrax Tower Scout enters, it triggers, untapping Emry.
5. Activate Dark Sphere by tapping and sacrificing it.
6. Repeat.

This ingenious loop turns Emry, Lurker of the Loch into a relentless engine by utilizing her tap ability to repeatedly pull Dark Sphere from the graveyard for free. Every time you cast that zero-mana artifact, Displacer Kitten's avoidance ability triggers to blink Hyrax Tower Scout, whose entrance trigger then untaps Emry, Lurker of the Loch so she can immediately start the cycle over again. Because Dark Sphere can be sacrificed right back to the graveyard during the sequence, you generate an endless storm of artifact and creature triggers without ever running out of resources.
