Emry, Lurker of the Loch + Displacer Kitten + Samut, Tyrant Smasher + Tormod's Crypt

Emry, Lurker of the Loch

Displacer Kitten

Samut, Tyrant Smasher

Tormod's Crypt

How it works

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

By leveraging Displacer Kitten's avoidance trigger every time you cast a noncreature spell, you can repeatedly blink Emry, Lurker of the Loch to refresh her tap ability and continuously trigger her mill effect upon re-entering the battlefield. Because Emry lets you cast artifacts from your graveyard, you cycle Tormod's Crypt for zero mana to fuel the kitten's noncreature spell requirement, all while Samut, Tyrant Smasher ensures Emry's tapped status doesn't interfere with your ability to tap her right back into action. This infinite loop lets you mill your entire library while generating boundless artifact and creature triggers.
