A few thoughts on this chapter, which I hope to send into One Piece Podcast:
It seems to me that the Blackbeard Pirates' Devil Fruit, excluding the ones who already had them like Lafitte and Kuzan, seem designed to enhance what they're already very good at. Strength for Burgess, teleportation for Van Augur the sniper, diseases for Doc Q, gigantification for Wolf, liquor for Vasco Shot.
Thinking about this reminded me of one detail that's always stuck in my mind about Blackbeard: He was the first character we ever saw explicitly hunting a specific Devil Fruit. Everyone else up to that point we either don't know how they got it or it was an accident. Makes me wonder how long he had this plan of his in place to power up his people with Devil Fruits the same way Kaido wanted his army of Zoans.
One last point on the Blackbeard pirates (this was mentioned in the spoiler thread), back in chapter 803 there was a discussion between Dragon and Koala about weapons made of "Drunken Iron Ore", which only a few places could produce. Now we learn Blackbeard has a literal booze man. There's a possible connecting line being drawn there.
Also, the way Garp's ship launched itself into Fullalead, the Thousand Sunny won't be able to escape them with Coup de Burst now.
Thinking about the reveal of SWORD as the Navy's "Mission: Impossible" unit, I wonder now if Kuzan isn't playing a long game. I expect that's already a theory, but now I wonder if we might not get a reveal that Kuzan won the duel that terraformed Punk Hazard, gave Sakazuki the Fleet Admiral position anyway, and leveraged that into Sakazuki's support/cooperation with his own plan, which might be why Sakazuki has had to play desk jockey, he's honor bound to not go whole hog and run things like Kuzan would. There's also the possibility that both were in on it from the get-go, the entire duel was a sham, and the entire goal was to give Kuzan a way to leave the Navy in spectacular fashion. Sakazuki has been obeying the true Fleet Admiral all along.
