Morophon, the Boundless + Sparkcaster + Fist of Suns

Morophon, the Boundless

Sparkcaster

Fist of Suns

How it works

1. Cast Sparkcaster by paying 0.
2. When Sparkcaster enters, it triggers, returning itself from the battlefield to your hand.
3. Repeat.

This mesmerizing loop hinges on the incredible cost-reduction engine of Morophon, the Boundless combined with the alternative casting cost granted by Fist of Suns. By naming Sliver or another shared type for Morophon, its static ability slashes five colored mana from your spells, perfectly neutralizing the five-color requirement of Fist of Suns so you can cast anything for free. Because Sparkcaster is a red or green creature, its own enter-the-battlefield trigger forces it right back to your hand as it resolves. This lets you endlessly replay Sparkcaster for zero mana, repeatedly pinging opponents for infinite damage and building an astronomical storm count along the way.
