Displacer Kitten + Storm-Kiln Artist + Skycoach Conductor // All Aboard

Displacer Kitten

Storm-Kiln Artist

Skycoach Conductor // All Aboard

How it works

1. Cast a copy of the prepared spell from exile by paying one mana, unpreparing Skycoach Conductor // All Aboard.
2. When you cast this, Displacer Kitten and Storm-Kiln Artist triggers.
3. Resolve the Displacer Kitten ability, flickering Skycoach Conductor // All Aboard, which enters prepared.
4. Resolve the remaining trigger, creating a Treasure token.
5. Resolve the spell from step 1.
6. Activate the Treasure token by tapping and sacrificing it, adding one mana.
7. Repeat.
