Teshar, Ancestor's Apostle + Scrap Trawler + Krark-Clan Grunt + Delif's Cone

Teshar, Ancestor's Apostle

Scrap Trawler

Krark-Clan Grunt

Delif's Cone

How it works

1. Cast Delif's Cone by paying its mana cost.
2. Teshar triggers, returning Scrap Trawler from your graveyard to the battlefield.
3. Activate Delif's Cone by tapping and sacrificing it.
4. Activate Krark-Clan Grunt by sacrificing Scrap Trawler.
5. When Scrap Trawler dies, it triggers, returning Delif's Cone from your graveyard to your hand.
6. Resolve the Krark-Clan Grunt ability.
7. Repeat.

This ingenious loop turns cheap artifact recycling into a permanent engine of endless sacrifice and recursion. By casting Delif's Cone, you trigger Teshar, Ancestor's Apostle to constantly resurrect Scrap Trawler from your graveyard. From there, you can sacrifice Delif's Cone to its own ability and feed Scrap Trawler directly to Krark-Clan Grunt's activation cost; the dying Scrap Trawler's ability then bounces the original Delif's Cone right back to your hand so the whole cycle can begin anew.
