Emry, Lurker of the Loch + Displacer Kitten + Dragonlord Kolaghan + Welding Jar

Emry, Lurker of the Loch

Displacer Kitten

Dragonlord Kolaghan

Welding Jar

How it works

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

This clever loop relies on the constant recycling of artifacts to repeatedly trigger entry and exit abilities. By tapping Emry, Lurker of the Loch, you gain access to cast Welding Jar straight from your graveyard for a mere zero mana. Since Welding Jar is a noncreature spell, casting it triggers Displacer Kitten, which blinks Emry to reset her tap ability and immediately triggers her to mill four more cards. With Welding Jar sitting safely back in your graveyard, you can repeat this process endlessly while leaving Dragonlord Kolaghan to loom large over the battlefield as part of your active deck.
