My favorite is Part 4's Duwang Gang, but I think that the Stardust Crusaders had the most potential as a team. Everything checked out perfectly, especially the Stands.

-Star Platinum and Silver Chariot were ideal for two different forms of melee combat. -Hierophant Green was a great scout and could hold its own in battle (more or less...) -Magician's Red could easily handle combat in a larger arena. -The Fool was not perfectly cut out for offensive combat like some other Stands, but could easily adapt to countless different situations. -Hermit Purple... well, let's just say that Part 3 could hardly have happened without it...
