Well, up until the monster trio and Loki came back up, everything was going their way. Any giants who tries to stop it: Defeated. Hostages: Secured. Their demands: About to be fulfilled. Even Gaban was neutralized thanks to a little underhandedness. And the Straw Hats? Subdued.
99.99999% of the time they wouldn't have any problems. Its just that on Elbaf there was not just ONE abnormally strong person to screw up their plans, there was a whole Yonko crew, plus Gaban, plus LOKI, on top of the entire nation of Elbaf (including the Giant Warrior Pirates). And with only a handful of their members they kinda handled most of it just fine. Like, put any other 3 antagonists from any other crew/group here, thar aren't even anywhere close to being the strongest members of their faction, and most people don't perform as well as they did.
