About The World's Strongest Warriors (OP-17)

OP-17 lands on three fronts. The Straw Hat Crew arrives in Elbaf, with Luffy, Zoro, Nami, Usopp and the rest of the crew getting a full run of cards in Elbaf attire. The Rocks Pirates join the battle, led by the debut of Rocks D. Xebec (OP17-118) alongside Edward Newgate, Kaido, Wang Zhi, Captain John and Ganzui in their Rocks-era forms. And the Four Emperors assemble, giving the anniversary set its headline collector cards.

As the 4th Anniversary release, OP-17 also carries the game's new premium card treatments, including the first Super Leader Alt-Art.

What you're chasing

• OP17-079 Monkey D. Luffy Super Leader Alt-Art - the set's headline pull, a Leader card given the game's most premium alternate-art treatment yet (also known as the Super Leader Parallel)
• Four Emperors Manga Rares - Shanks, Whitebeard, Kaido and Big Mom are the widely tipped top-end chases
• Rocks D. Xebec (OP17-118) - the Rocks Pirates captain's first card in the game
• Treasure Rare - the rarity slot that sits above Secret Rare
• Special Cards, Super Alt-Arts and Secret Rares, plus the full Straw Hats in Elbaf attire alt-art run

Who this is for

• Players: a full box is the efficient way to build out the OP-17 card pool before the set hits tournament play.
• Collectors: 24 packs is the best odds-per-dollar route to the Super Leader Alt-Art, Manga Rares and Treasure Rare.
• Box breakers: an anniversary set with a deep chase ladder and strong on-camera pulls.
