Since I've had this deck taken apart for a while now, I have no way to confirm for certain which land was in that Flood Plain slot. It certainly wasn't actually a Flood Plain. Ordinarily, I'd guess that it was an autocomplete issue, as I've caught some of my decks on TappedOut using the wrong card name due to my failing to catch instances of autocomplete cropping up, but there's no land that would start with "Flo" that could have been the culprit in this case. I am almost 100% certain that whatever card was in this slot, it wasn't actually Flood Plain, as I piloted the deck enough times that the issue of the wrong fetchland being in the deck would have come up. And of course, even if Flood Plain had been mistakenly slotted into this deck, it really shouldn't have been. I didn't choose to go for those Streets of New Capenna forest-grabbing lands here, but they would probably have been fine.

Took this deck apart before the new MH3 fetches existed, but those would go in an updated version of this list.

The utility value of Ghost Town in this deck is extremely niche. It would have been another basic if I'd felt the need for more of those. Cutting it for one of the new fetchlands would also make sense. Some of the other utility lands are also mostly just there because enough of the slots seemed to be devoted to basics and getting a bit more utility seemed worth the negligible risk. Likewise, there was some silly cornercase reason for running a single Wastes. I can't remember that cornercase off the top of my head. That slot could just as easily be another forest anyway, but like I said, I always seemed to have enough basic forests.

City of Traitors is bonkers-good and would never, ever be cut from this deck. But everything else you said is solid.
