Yenna, Redtooth Regent + Angelic Renewal + Ashnod's Altar + Urabrask the Hidden

Yenna, Redtooth Regent

Angelic Renewal

Ashnod's Altar

Urabrask the Hidden

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 uses Yenna, Redtooth Regent to repeatedly clone Angelic Renewal, turning the enchantment's resurrection magic into a continuous engine. When you sacrifice Yenna to Ashnod's Altar for mana, the two copies of Angelic Renewal both trigger, allowing you to sacrifice one to return Yenna immediately while leaving the other behind to keep the cycle going. Meanwhile, Urabrask the Hidden ensures that Yenna and any other creatures you control return with haste and are ready to act instantly, while your opponents' creatures enter the battlefield safely tapped.
