This intricate loop relies on Saffi Eriksdotter's ability to constantly rescue Junji, the Midnight Sky from the grave whenever Ayli, Eternal Pilgrim sacrifices the Dragon for life. Because Junji's death trigger can itself recur Saffi back to the battlefield, the two legends form a self-sustaining sacrifice engine. Meanwhile, Honor-Worn Shaku acts as the crucial mana engine, tapping both legendary creatures to repeatedly untap itself and generate infinite colorless mana to sustain the loop.
