Prossh, Skyraider of Kher + Earthcraft + Phyrexian Altar

Prossh, Skyraider of Kher

Earthcraft

Phyrexian Altar

How it works

1. Activate a basic Swamp, Mountain and Forest by tapping them, adding .
2. Cast Prossh from the command zone by paying 3 plus commander tax, if applicable.
3. Prossh triggers, creating a number of 0/1 Kobolds of Kher Keep tokens equal to the amount of mana spent to cast Prossh.
4. Activate Earthcraft three times by tapping two Kobolds of Kher Keep tokens and Prossh, untapping a basic Swamp, Mountain and Forest.
5. Activate Phyrexian Altar by sacrificing Prossh, adding CC.
6. Choose to return Prossh from your graveyard to the command zone.
7. Activate Phyrexian Altar by sacrificing a Kobolds of Kher Keep token, adding CC.
8. Repeat step 7 until you have enough mana to cast Prossh.
9. Repeat from step 1.

This elegant loop turns the natural synergy of Prossh, Skyraider of Kher and its swarm of Kobolds of Kher Keep into an unstoppable engine. By leveraging Earthcraft, you can continuously untap your basic lands using your creatures—including Prossh itself—while Phyrexian Altar converts your expendable tokens and the commander into a steady stream of mana. As you recast Prossh over and over, the expanding tide of entering and dying creatures fuels an infinite cascade of resources, allowing you to drown your opponents in overwhelming power and endless dragon casts.
