Archon of Falling Stars + Animate Dead + Ashnod's Altar

Archon of Falling Stars

Animate Dead

Ashnod's Altar

How it works

1. Activate Ashnod's Altar by sacrificing Archon of Falling Stars, adding CC.
2. When Archon of Falling Stars dies, it triggers, returning Animate Dead from your graveyard to the battlefield.
3. When Animate Dead enters the battlefield, it triggers, returning Archon of Falling Stars from your graveyard to the battlefield, and attaching Animate Dead to it.
4. Repeat.
