Thousand-Year Storm + Storm-Kiln Artist + Unsubstantiate

Thousand-Year Storm

Storm-Kiln Artist

Unsubstantiate

How it works

1. Cast any instant or sorcery by paying its mana cost.
2. Holding priority, cast Unsubstantiate by paying 1, targeting that spell.
3. Thousand-Year Storm and Storm-Kiln Artist trigger.
4. Resolve the Storm-Kiln Artist trigger, creating a Treasure token.
5. Resolve the Thousand-Year Storm trigger, copying Unsubstantiate once for each instant or sorcery you've cast before it this turn, with each copy targeting the original Unsubstantiate.
6. Storm-Kiln Artist triggers for each copy made this way, creating that many Treasure tokens.
7. Resolve the first copy of Unsubstantiate, returning the original Unsubstantiate to your hand.
8. All remaining Unsubstantiate copies fizzle due to no longer having a legal target.
9. Holding priority, activate the Treasures by tapping and sacrificing them, adding 1.
10. Repeat from step 2.

This dazzling loop turns the cascading power of Thousand-Year Storm into an engine for infinite mana and astronomical storm counts. As you cast spells, Storm-Kiln Artist acts as your financial backbone, continuously generating Treasure tokens both when spells are cast and when they are copied. By targeting your own Unsubstantiate with its own copies, you can continuously return the original to your hand while feeding your magecraft triggers and generating more than enough Treasures to pay for the loop indefinitely.
