Teshar, Ancestor's Apostle + Scrap Trawler + Lotus Petal + Yahenni, Undying Partisan

Teshar, Ancestor's Apostle

Scrap Trawler

Lotus Petal

Yahenni, Undying Partisan

How it works

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

This engine thrives on a recycling loop where Teshar, Ancestor's Apostle acts as the resurrection engine, bringing back Scrap Trawler from the graveyard every time you cast a historic spell. Sacrificing Lotus Petal generates the initial mana while feeding the graveyard, which in turn triggers Scrap Trawler to hand the Petal right back to you so you can recast it as a historic spell. Meanwhile, Yahenni, Undying Partisan serves as the willing executioner to send Scrap Trawler to the graveyard on command, creating an endless cycle of artifact entry, sacrifice, and mana production.
