This clever loop turns any initial instance of lifegain into a self-sustaining engine of continuous growth and artifact generation. It all hinges on Biotransference, whose static ability ensures that every creature token entering the battlefield—including the Eldrazi Spawn from Basking Broodscale and the Necron Warrior from Biotransference itself—is also an artifact. That classification is the crucial bridge: whenever one of those artifacts enters, Teething Wurmlet triggers to give you life, which in turn fires off Spider-Man, Peter Parker's triggered ability to place a +1/+1 counter back onto Basking Broodscale. That counter placement triggers Basking Broodscale's adapt-style ability to spawn another token, restarting the entire chain of life, counters, and artifact entries indefinitely.
