The Necrobloom + Six + Chromatic Sphere + Shuri, Wakandan Inventor

The Necrobloom

Six

Chromatic Sphere

Shuri, Wakandan Inventor

How it works

1. Cast Chromatic Sphere from your graveyard by paying 0 and discarding a land card from your hand.
2. Activate Chromatic Sphere by paying 1, tapping and sacrificing it, adding 1 and causing you to mill two cards and return a land card from your graveyard to your hand.
3. Repeat.

This ingenious loop relies on Six to grant retrace to your nonland permanents, allowing you to cast Chromatic Sphere directly from your graveyard for a mana value of zero by discarding a land card. Shuri, Wakandan Inventor reduces that cost further and helps orchestrate your artifact synergies, while The Necrobloom transforms every land card in your graveyard into a dredger, fueling your hand whenever you need fodder for retrace. As you crack and recur Chromatic Sphere over and over again, its built-in draw replacement and the interaction with your graveyard engine churn through your entire library to build a staggering storm count.
