How it works
Cast Mishra's Bauble by paying its mana cost.
Teshar triggers, returning Scrap Trawler from your graveyard to the battlefield.
Activate Mishra's Bauble by tapping and sacrificing it.
Activate Thermopod by sacrificing Scrap Trawler.
When Scrap Trawler dies, it triggers, returning Mishra's Bauble from your graveyard to your hand.
Repeat.
This intricate loop sets up an endless engine of sacrifice and recursion, fueled by Teshar, Ancestor's Apostle watching over your historic spells. When you cast Mishra's Bauble, Teshar triggers to pull Scrap Trawler straight out of the graveyard and back onto the battlefield. From there, you sacrifice Mishra's Bauble for its card draw, and then feed Scrap Trawler to Thermopod to generate red mana and trigger the Trawler's ability. That death trigger lets you retrieve Mishra's Bauble right back to your hand, allowing you to cast it again and repeat the entire process indefinitely.
