Surprised to see Alomomola and Torn T not rising, I've found then to be quite excellent in this meta, maybe next month. Rilla and Moon rises make sense, but Blissey is pretty wild, Bloona has the tier in quite a stranglehold. The crazy drops don't surprise me as much, Heatran is kinda bad this gen, but I thought Garchomp would still be around since I saw it quite a lot in the first week of dlc, though it did drop off after. Ribombee staying OU is hilarious though.
What I do find more interesting though is Great Tusk having a pretty big drop off from last month's ~41 to now 30% while Kingambit is head and shoulders above it at 41.
