Ozox, the Clattering King + Phyrexian Altar + Gutter Grime

Ozox, the Clattering King

Phyrexian Altar

Gutter Grime

How it works

1. Activate Phyrexian Altar by sacrificing Ozox, adding 1.
2. When Ozox dies, it and Gutter Grime trigger.
3. Resolve the Ozox trigger, creating a legendary 2/1 Jumblebones creature token.
4. Resolve the Gutter Grime trigger, putting a slime counter on it and creating a creature token.
5. Activate Phyrexian Altar twice by sacrificing Jumblebones and the other creature token, adding 1.
6. When Jumblebones dies, it triggers, returning Ozox from your graveyard to your hand.
7. Cast Ozox by paying 2.
8. Repeat.

This clever loop sets up an endless cycle of sacrifice and rebirth, turning your graveyard into a revolving door of skeletal royalty. By feeding Ozox, the Clattering King to Phyrexian Altar, you trigger its death ability to create Jumblebones while simultaneously fueling Gutter Grime to steadily grow an army of massive Ooze tokens. When you subsequently sacrifice Jumblebones to the Altar for mana, its leaves-the-battlefield trigger cleverly plucks Ozox right back out of your graveyard and into your hand, leaving you with more than enough resources to recast Ozox and repeat the entire process indefinitely.
