@The:
Yeah… I could see Urouge + Luffy + Law. But to be honest, I still think X. Drake is going to jump aboard once the opportunity arises, and that will be the "three-way" (because X. Drake's Ancient Zoan is also brawn).
It just seems unlikely to me that every single supernova is going to the New World and will all rebel against the Yonkou and not either a) want to join one of them in the first place or b) be persuaded to join as Ace was to join the Whitebeard Pirates.
So far we have 7 of the 11SN being confirmed as fighting against a Yonkou, leaving us with Drake, Bonney, Bege and Urouge. Just by the way we were shown Drake's interaction with Scotch I do get the feeling that we're getting a curveball and Drake will now be a subordinate of Kaidou.
We were shown enough aggression from Drake as to make it seem obvious that this was in fact a declaration of war against one of the yonkou. But the way Drake phrased it, "Will attacking you get Kaidou's attention?", seems to leave it purposefully ambiguous.
So going by the odds and by Drake's phrasing , I really do see Drake now being in cahoots with the strongest creature in the world.
