How it works
Cast Urza's Bauble by paying its mana cost.
Teshar triggers, returning Scrap Trawler from your graveyard to the battlefield.
Activate Urza's Bauble by tapping and sacrificing it.
Activate Krark-Clan Grunt by sacrificing Scrap Trawler.
When Scrap Trawler dies, it triggers, returning Urza's Bauble from your graveyard to your hand.
Resolve the Krark-Clan Grunt ability.
Repeat.
This loop relies on an intricate recycling engine where Teshar, Ancestor's Apostle acts as the focal point, continuously resurrecting Scrap Trawler from your graveyard every time you cast a historic spell. To fuel this, Urza's Bauble serves as the cheap historic artifact that triggers Teshar while also putting itself into the graveyard to be retrieved later. The key to sustaining this momentum is Scrap Trawler's ability to pull that Bauble back into your hand whenever another artifact heads to the yard. Meanwhile, Krark-Clan Grunt acts as the sacrifice outlet that feeds the Trawler's trigger while growing massively in power each iteration.
