Swarm Intelligence + Storm-Kiln Artist + Reprieve

Swarm Intelligence

Storm-Kiln Artist

Reprieve

How it works

1. Cast any card by paying its mana cost, or wait for an opponent to cast one.
2. Holding priority, cast Reprieve by paying 1, targeting that spell.
3. Swarm Intelligence and Storm-Kiln Artist trigger.
4. Resolve the Storm-Kiln Artist trigger, creating a Treasure token.
5. Resolve the Swarm Intelligence trigger, copying Reprieve, with the copy targeting the original Reprieve.
6. Storm-Kiln Artist triggers, creating a Treasure token.
7. Resolve the copy of Reprieve, returning the original Reprieve to your hand and causing you to draw a card.
8. Holding priority, activate the Treasures by tapping and sacrificing them, adding 1.
9. Repeat from step 2.

This cunning loop begins the moment you unleash Reprieve, which immediately catches the attention of Swarm Intelligence and Storm-Kiln Artist alike. While Swarm Intelligence dutifully generates a fresh copy of Reprieve to bounce the original back to your hand for reuse, Storm-Kiln Artist's magecraft ability turns every single cast and copy into a fresh Treasure token. Sacrificing those Treasures readily refunds the exact white mana needed to keep casting Reprieve over and over again, fueling near-infinite magecraft triggers, drawing your entire deck, and driving your storm count through the roof.
