Teshar, Ancestor's Apostle + Scrap Trawler + Yahenni, Undying Partisan + Dark Sphere

Teshar, Ancestor's Apostle

Scrap Trawler

Yahenni, Undying Partisan

Dark Sphere

How it works

1. Cast Dark Sphere by paying its mana cost.
2. Teshar triggers, returning Scrap Trawler from your graveyard to the battlefield.
3. Activate Dark Sphere by tapping and sacrificing it.
4. Activate Yahenni by sacrificing Scrap Trawler.
5. When Scrap Trawler dies, it triggers, returning Dark Sphere from your graveyard to your hand.
6. Resolve the Yahenni ability.
7. Repeat.

This ingenious loop transforms humble graveyard recursion into an endless engine of sacrifice and resurrection, fueled by the recursive synergy between Teshar, Ancestor's Apostle and Scrap Trawler. By casting the zero-mana artifact Dark Sphere, you trigger Teshar to pull Scrap Trawler back from the graveyard onto the battlefield. You then sacrifice Scrap Trawler to Yahenni, Undying Partisan's activation, which in turn triggers Scrap Trawler to pluck Dark Sphere right back out of your graveyard and into your hand. This leaves Yahenni safely fed with a +1/+1 counter and ready to protect your board with indestructible, allowing you to replay the sphere and repeat the entire sequence indefinitely.
