Yenna, Redtooth Regent + Angelic Renewal + Ashnod's Altar + Temur Ascendancy

Yenna, Redtooth Regent

Angelic Renewal

Ashnod's Altar

Temur Ascendancy

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 loop transforms Yenna, Redtooth Regent into an endless engine of resurrection by exploiting the stacking triggers of duplicated enchantments. By using Yenna's tap ability to copy a baseline Angelic Renewal, you set up a situation where sacrificing Yenna to Ashnod's Altar immediately triggers multiple copies of Angelic Renewal to return her right back to the battlefield. Meanwhile, Temur Ascendancy sits comfortably on the board granting haste and drawing you cards off every creature that enters with power 4 or greater, though here its primary role is completing the enchantment-heavy architecture that fuels the engine.
