This clever loop turns the top of your library into an endless engine by leveraging the top-deck manipulation of Sensei's Divining Top alongside the card-casting freedom of One with the Multiverse. Because One with the Multiverse lets you play spells directly from the top, and Elven Chorus allows your creatures to tap for mana while letting you cast creature spells from the top, you have all the tools needed to keep recasting the artifact. Traxos, Scourge of Kroog holds the physical labor together by acting as a mana source through Elven Chorus's activated ability while simultaneously untapping itself each time you cast the historic Sensei's Divining Top, endlessly churning through your deck to draw your entire library.
