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 Ashnod's Altar by sacrificing Scrap Trawler.
When Scrap Trawler dies, it triggers, returning Mishra's Bauble from your graveyard to your hand.
Repeat.
This loop transforms a humble zero-mana artifact into an infinite recycling engine, fueled by the recursive prowess of Teshar, Ancestor's Apostle and Scrap Trawler working in tandem. When you cast Mishra's Bauble, Teshar triggers to pluck Scrap Trawler from your graveyard, while Ashnod's Altar stands ready to sacrifice that Trawler for colorless mana whenever needed. Because Scrap Trawler looks at the mana value of artifacts going to the graveyard from the battlefield, sacrificing the Bauble and then the Trawler sets up a net-positive loop that returns the Bauble directly back to your hand to be recast.
