Yenna, Redtooth Regent + Angelic Renewal + Ashnod's Altar + Samut, Voice of Dissent

Yenna, Redtooth Regent

Angelic Renewal

Ashnod's Altar

Samut, Voice of Dissent

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 loop centers on Yenna, Redtooth Regent duplicating Angelic Renewal to set up an engine of endless sacrifices and returns. By using Ashnod's Altar, you not only harvest the mana needed to keep Yenna's ability active but also send Yenna straight to the graveyard, triggering the nested safety nets of Angelic Renewal and its token copy. Samut, Voice of Dissent quietly pieces the puzzle together from the sidelines, granting Yenna the crucial untap ability to bypass summoning sickness and tap repeatedly (alongside its haste-granting presence), ensuring the whole operation can run seamlessly.
