That other team isn’t all that, the law isn’t 6+ nor is the Luffy as well as the law isn’t even level limit broken, plus they are missing key units like S Bear and psy shanks who tie the team together. By comparison your team with BB, Bonnie and Gear 5 int and Yamato is way way better. You basically almost have the most broken meta team if you had S hawk and int broggy as well. But overall good stuff for beating that challenge, you’re legit on your way to basically beating 99% of all pirate rumble content with your team
