Delivery Moogle + Displacer Kitten + Lotus Petal + Welding Jar

Delivery Moogle

Displacer Kitten

Lotus Petal

Welding Jar

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 elegant loop centers on the relentless blinking power of Displacer Kitten, which triggers every time you cast a noncreature spell to exile and return a nonland permanent you control. By targeting Delivery Moogle with the Kitten's ability, you can repeatedly trigger the Moogle's entrance effect to cycle either Lotus Petal or Welding Jar from your library or graveyard directly into your hand. You then simply cast that retrieved artifact as your noncreature spell, generating mana with the Petal or using the Jar as needed while restarting the entire sequence.
