Krark, the Thumbless, Storm-Kiln Artist, Quantum Misalignment, and Multiversal Incursion

Prerequisites

• Krark, the Thumbless on the battlefield
• Storm-Kiln Artist on the battlefield
• Quantum Misalignment in hand
• Multiversal Incursion on the battlefield
• available

Steps

1. Cast Multiversal Incursion by paying its mana cost, targeting Krark
2. When you cast Multiversal Incursion, Krark, any additional copies of Krark, and Storm-Kiln Artist trigger
3. Resolve the Storm-Kiln Artist trigger, creating a Treasure token
4. Activate a Treasure token by tapping and sacrificing it, adding one mana of any color
5. Resolve a Krark trigger, flipping a coin and returning the Multiversal Incursion card to your hand if you lose and copying it if you win
6. If you copy Multiversal Incursion, Storm-Kiln Artist triggers again, causing you to repeat steps 3 to 4
7. Repeat steps 5—6 for each Krark trigger
8. If Multiversal Incursion is back in your hand, repeat from step 1
9. If you won every flip, instead resolve the Multiversal Incursion card itself, creating one more Krark token and putting the card into your graveyard
10. Repeat steps 1 through 9 with Quantum Misalignment, if you still need more Krark copies
11. If you manage to pass a critical threshold of Krark copies before both Multiversal Incursion and Quantum Misalignment end up in your graveyard, this combo is overwhelmingly likely to be an infinite loop from that point on
12. See the widget below for failure chances
13. Once you have infinite mana and infinite copies of Krark, you can repeat this loop with any instant or sorcery you can cast

Results

• Infinite artifact ETB
• Infinite artifact LTB
• Infinite copies of creatures you control
• Infinite copies of instant or sorcery spells you cast
• Infinite magecraft triggers
