Also, last swamp is 261/269: eight more nonbasic lands?

5 dual color and 3 others?

Seems like a lot. And all after Sw. Maybe Temples? Or another cycle with common first word in the name? Not likely to be Glacial Fortress et al

The UGH-PITS~!

Apparently, enemy pain lands only contribute Yavimaya Coast, and MTGS says Urborg is in - but that's just two

also noting how mtgs spoiler has not reflected my observation

mistaken! the cards in the spoiler are arranged alphabetically, but basics are numbered as usual

i guess what's notable is soul of new phyrexia is 231 and battlefield forge is 240. the staves are back, as in mtgs spoiler, so that's 3 more artifacts (or lands before ba). also, 242 and 243 are missing

the mythic cycles are strange for m15: two six-card cycles (where one has an artifact, another a GB card), two artifacts and a 5-color sliver lord

243 lang pala, between Darksteel Citadel (242) and Llanowar Wastes (244)

double counted soul of new phyrexia. so 6 souls, 6 pws, perilous vault, sliver lord and one more mythic

reading the story, I had a chill before the reveal. now that's your last mythic. funny how many new cards say planeswalker now
