Teshar, Ancestor's Apostle + Scrap Trawler + Krark-Clan Grunt + Tormod's Crypt

Teshar, Ancestor's Apostle

Scrap Trawler

Krark-Clan Grunt

Tormod's Crypt

How it works

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

This ingenious recursion loop is anchored by Teshar, Ancestor's Apostle, which rewards you with a free creature from your graveyard every time you cast a historic spell. To fuel this engine, Tormod's Crypt acts as a zero-mana historic spell that conveniently loops right back to your hand when sacrificed, courtesy of Scrap Trawler's graveyard-recycling triggered ability. Meanwhile, Krark-Clan Grunt serves as your willing executioner, providing a reliable sacrifice outlet that triggers the Scrap Trawler while also receiving a nice, albeit unnecessary, power boost for your troubles.
