This clever loop turns your topdeck into an endless engine by using Crystal Skull, Isu Spyglass to cast Sensei's Divining Top directly from the library while letting you look ahead. To fuel the mana cost of recasting the Top, Traxos, Scourge of Kroog pulls double duty: its drawback is bypassed because each time you cast Sensei's Divining Top—which counts as a historic spell—it triggers Traxos to untap, allowing you to tap Traxos right back for mana thanks to the passive ability granted by Enduring Vitality. Because Sensei's Divining Top draws a card before returning to the library, you continuously cycle through your deck while stacking up endless artifact triggers and storm count.
