Yenna, Redtooth Regent + Angelic Renewal + Ashnod's Altar + Anger

Yenna, Redtooth Regent

Angelic Renewal

Ashnod's Altar

Anger

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 sets up an infinite engine by leveraging Yenna, Redtooth Regent to constantly duplicate Angelic Renewal, which conveniently bypasses its own legendary restriction to let multiple copies coexist. When you sacrifice Yenna to Ashnod's Altar, both Angelic Renewal triggers fire off simultaneously, allowing one copy to return Yenna to the battlefield while the other stays behind for future loops, all while funding Yenna's ability and generating a surplus of mana. Meanwhile, having Anger in your graveyard provides a crucial passive haste buff to ensure Yenna can immediately tap and restart the cycle the moment she returns.
