Yenna, Redtooth Regent + Angelic Renewal + Ashnod's Altar + Lightning Greaves

Yenna, Redtooth Regent

Angelic Renewal

Ashnod's Altar

Lightning Greaves

How it works

1. Activate Lightning Greaves' equip ability by paying 0, attaching it to Yenna.
2. Activate Yenna by paying 2 and tapping it, creating a token copy of Angelic Renewal.
3. Activate Ashnod's Altar by sacrificing Yenna, adding CC.
4. When Yenna dies, both Angelic Renewals trigger.
5. Resolve the first trigger, choosing to sacrifice either Angelic Renewal and return Yenna from your graveyard to the battlefield.
6. Resolve the second trigger, choosing not to pay.
7. Repeat.

By outfitting Yenna, Redtooth Regent with Lightning Greaves, you grant her the shroud she needs to operate safely while instantly moving the boots for free. This allows Yenna to tap and pay {2} to duplicate Angelic Renewal, turning her tap ability into a self-sustaining engine. When you feed Yenna to Ashnod's Altar for two generic mana—which conveniently covers Yenna's activation cost—her death triggers both copies of Angelic Renewal simultaneously. You simply sacrifice one copy to bring Yenna straight back to the battlefield, leaving the second Angelic Renewal behind to ensure the loop can be repeated indefinitely.
