Unctus, Grand Metatect + Kiora's Follower + Fatestitcher

Unctus, Grand Metatect

Kiora's Follower

Fatestitcher

How it works

1. Activate Fatestitcher by tapping it, targeting Kiora's Follower.
2. Fatestitcher triggers, causing you to loot.
3. Resolve the Fatestitcher ability, untapping Kiora's Follower.
4. Activate Kiora's Follower by tapping it, targeting Fatestitcher.
5. Kiora's Follower triggers, causing you to loot.
6. Resolve the Kiora's Follower ability, untapping Fatestitcher.
7. Repeat.

This clever engine gets its propulsion from Unctus, Grand Metatect, whose passive ability grants your blue creatures a helpful loot trigger whenever they become tapped. By using {U/P} to turn Kiora's Follower into a blue artifact, both it and Fatestitcher qualify for Unctus's pump and looting effects. The loop then sustains itself infinitely because Fatestitcher taps to untap Kiora's Follower—which in turn taps to untap Fatestitcher—generating an endless cycle of untaps that continuously triggers Unctus to churn through your entire deck.
