Sun Titan + Angelic Renewal + Yahenni, Undying Partisan

Sun Titan

Angelic Renewal

Yahenni, Undying Partisan

How it works

1. Activate Yahenni by sacrificing Sun Titan.
2. When Sun Titan dies, Angelic Renewal triggers, causing you to sacrifice Angelic Renewal and return Sun Titan from your graveyard to the battlefield.
3. When Sun Titan enters, it triggers, returning Angelic Renewal from your graveyard to the battlefield.
4. Resolve the Yahenni ability.
5. Repeat.

This clever loop turns a simple recursion engine into an endless cycle of sacrifice and rebirth by trading resources between the graveyard and the battlefield. When you feed Sun Titan to Yahenni, Undying Partisan's activated ability, the Titan's death immediately triggers Angelic Renewal to save it and return it straight to play. That very entrance triggers Sun Titan's own ability, pulling Angelic Renewal right back out of the graveyard to set the stage for the next iteration. Yahenni happily grows with each cycle while keeping the engine safe from collateral damage, generating infinite deaths, leaves-the-battlefield triggers, and enters-the-battlefield triggers without ever losing a piece.
