Teshar, Ancestor's Apostle + Scrap Trawler + Lotus Petal + Arcbound Ravager

Teshar, Ancestor's Apostle

Scrap Trawler

Lotus Petal

Arcbound Ravager

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 Arcbound Ravager by sacrificing Scrap Trawler.
5. When Scrap Trawler dies, it triggers, returning Lotus Petal from your graveyard to your hand.
6. Resolve the Arcbound Ravager ability.
7. Repeat.

This loop turns a modest graveyard into a self-sustaining engine by cycling free artifacts through the battlefield and your hand. You start by casting Lotus Petal, which triggers Teshar, Ancestor's Apostle to resurrect Scrap Trawler from the graveyard. You then sacrifice Lotus Petal for mana and feed Scrap Trawler to Arcbound Ravager's sacrifice outlet. Because Scrap Trawler hits the graveyard, its own ability triggers to return the sacrificed Lotus Petal straight back to your hand, allowing you to recast it as a historic spell and restart the entire cycle.
