Delivery Moogle + Displacer Kitten + Delif's Cone + Tormod's Crypt

Delivery Moogle

Displacer Kitten

Delif's Cone

Tormod's Crypt

How it works

1. Cast the artifact in your hand by paying its mana cost.
2. Displacer Kitten triggers, blinking Delivery Moogle.
3. When Delivery Moogle enters, it triggers, searching your library or graveyard for the other artifact and putting it into your hand.
4. Activate the artifact cast in step 1 by sacrificing it.
5. Repeat.

This loop relies on Displacer Kitten's passive ability to turn every noncreature spell into a blink engine for Delivery Moogle. When you cast either Delif's Cone or Tormod's Crypt, the Kitten's avoidance trigger exiles and returns the Moogle, whose entry ability immediately searches your library or graveyard for the other cheap artifact and puts it into your hand. By alternating between playing the Cone and the Crypt, you can continuously cast artifacts, sacrifice them for their effects, and replay them to fuel infinite artifact enters-the-battlefield, leaves-the-battlefield, sacrifice triggers, and storm count.
