Ozox, the Clattering King + Ashnod's Altar + Chromatic Orrery

Ozox, the Clattering King

Ashnod's Altar

Chromatic Orrery

How it works

1. Activate Ashnod's Altar by sacrificing Ozox, adding CC.
2. When Ozox dies, it triggers, creating a legendary 2/1 Jumblebones creature token.
3. Activate Ashnod's Altar by sacrificing Jumblebones, adding CC.
4. When Jumblebones dies, it triggers, returning Ozox from your graveyard to your hand.
5. Cast Ozox by paying 2.
6. Repeat.

This clever loop lets you sacrifice your commander over and over thanks to a clever cycle of mortality and recursion. You feed Ozox, the Clattering King into Ashnod's Altar for colorless mana, triggering its demise to produce the Jumblebones token. That token is then immediately sacrificed back to Ashnod's Altar, whose mana fuels recasting Ozox while simultaneously triggering Jumblebones' leave-the-battlefield ability to bounce Ozox right back to your hand. Meanwhile, Chromatic Orrery sits on the board ensuring that the copious colorless energy generated by the Altar can be smoothly filtered and spent as mana of any color.
