Morophon, the Boundless + Ancestral Statue + Leyline of Mutation

Morophon, the Boundless

Ancestral Statue

Leyline of Mutation

How it works

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

This elegant loop transforms Ancestral Statue into a completely free-casting engine, thanks to Leyline of Mutation letting you pay {W}{U}{B}{R}{G} for any spell and Morophon, the Boundless covering that exact five-color cost for your chosen creature type. Because Morophon makes the Statue free to cast, you can repeatedly play it and let its mandatory enters-the-battlefield trigger bounce itself right back to your hand. This perpetual motion machine generates infinite storm count along with an endless stream of creature enters-the-battlefield and leaves-the-battlefield triggers to fuel whatever payoff you need.
