Yenna, Redtooth Regent + Angelic Renewal + Ashnod's Altar + Frostcliff Siege

Yenna, Redtooth Regent

Angelic Renewal

Ashnod's Altar

Frostcliff Siege

How it works

1. Activate Yenna by paying 2 and tapping it, creating a token copy of Angelic Renewal.
2. Activate Ashnod's Altar by sacrificing Yenna, adding CC.
3. When Yenna dies, both Angelic Renewals trigger.
4. Resolve the first trigger, choosing to sacrifice either Angelic Renewal and return Yenna from your graveyard to the battlefield.
5. Resolve the second trigger, choosing not to pay.
6. Repeat.

This clever engine harnesses Yenna, Redtooth Regent's ability to duplicate enchantments, using it to turn Frostcliff Siege into a steady stream of Aura copies. By creating a token copy of Angelic Renewal, you set up an unyielding safety net whenever Ashnod's Altar demands a creature sacrifice. Sending Yenna to the graveyard triggers both Angelic Renewal and its copy, allowing you to seamlessly pull her right back to the battlefield while leaving the other behind as fresh fodder for infinite sacrifices.
