Enduring Renewal + Deathrender + Yahenni, Undying Partisan

Enduring Renewal

Deathrender

Yahenni, Undying Partisan

How it works

1. Activate Yahenni by sacrificing the creature with Deathrender attached.
2. When the creature dies, Enduring Renewal and Deathrender trigger.
3. Resolve the Enduring Renewal trigger, returning the creature from your graveyard to your hand.
4. Resolve the Deathrender trigger, putting the creature from your hand onto the battlefield, and attaching Deathrender to it.
5. Resolve the Yahenni ability.
6. Repeat.

This crafty loop sets up an endless cycle of sacrifice and rebirth by letting Deathrender and Enduring Renewal catch your creatures as they fall. When you sacrifice your equipped threat to Yahenni, Undying Partisan, Enduring Renewal swoops in to bounce that creature straight back to your hand from the graveyard. Meanwhile, Deathrender triggers off that same death to immediately redeploy the creature from your hand and reattach itself, setting the stage to do it all over again.
