Sedraxis Alchemist + Rooftop Storm

Sedraxis Alchemist

Rooftop Storm

How it works

1. Cast Sedraxis Alchemist by paying 0.
2. Sedraxis Alchemist enters the battlefield, returning itself to your hand.
3. Repeat.

With Rooftop Storm laying down a free-casting foundation that lets you bypass mana costs entirely for Zombie creature spells, Sedraxis Alchemist finds itself in a brilliant recursive loop. Each time you cast Sedraxis Alchemist for zero mana, its enter-the-battlefield ability triggers, compelling it to bounce itself right back to your hand since you naturally control blue permanents (like the Alchemist itself). This creates an endless cycle that effortlessly racks up infinite creature enter-the-battlefield triggers, leave-the-battlefield triggers, and a towering storm count.
