This ingenious loop relies on an endless cycle of sacrifice and rebirth, masterminded by Boonweaver Giant and Abduction working in tandem. When you sacrifice the Giant to Yahenni, Undying Partisan, Abduction's delayed trigger immediately rescues the Giant from the graveyard and returns it to the battlefield. Because Boonweaver Giant's enters-the-battlefield ability lets you fetch an Aura straight from your graveyard, it seamlessly pulls Abduction right back out with it, attaching it fresh and ready for the next iteration. Yahenni happily grows with +1/+1 counters along the way, turning this recursive engine into an endless torrent of entry, departure, and death triggers.
