Emry, Lurker of the Loch + Displacer Kitten + Lotus Petal + Frostcliff Siege

Emry, Lurker of the Loch

Displacer Kitten

Lotus Petal

Frostcliff Siege

How it works

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

This clever loop relies on Emry, Lurker of the Loch to constantly fish Lotus Petal out of your graveyard, utilizing the free mana artifact over and over to fund your spells while filling your graveyard further with her mill trigger. Whenever you cast that Lotus Petal, Displacer Kitten's avoidance trigger steps in to blink Emry, resetting her tap ability and triggering a fresh enter-the-battlefield mill. While Frostcliff Siege sits on the board silently providing its chosen banner effects, the Kitten and Emry turn a simple zero-mana artifact into an infinite engine of sacrifices, storm count, and colored mana.
