You think Rayleigh clashed with the likes of Vista, Rakuyo or young Marco, young Jozu for 3 days?
The most reasonable assumption is second strongest vs second strongest, which means Rayleigh vs. Oden unless they somehow say that it never happened, and they never said that.
Oden was going to fight Rayleigh + Gaban at the same time if Roger didn't interfere. Then Roger match up with WB, Oden could continue with Rayleigh.
Where is this certainty coming from?
I said Zolo needs CoC to reach Oden, that's why Oda gave him CoC in the exact same arc where he needed to use Enma.
But at the same time, Oden never splitted heavens. That could be the limit so far, if Oden or Rayleigh shows heaven splitting, then Zolo can get one.
While Zolo fans were saying CoC is useless and Ad.CoC doesn't exist. And Zolo doesn't need CoC. That's what Zolo fans were saying, you need a correction.
