Got some middle of Season 9 nominations for ya':
Rises
Rise from A- to A
Its usage ranking is #18 and it has a grand total of 10 showings in Season 8's top 100 teams. I can't say I see this thing very often myself, but I think the data speaks for itself on this one.
Rise from A- to A
Scizor has once again skyrockted in usage, sitting pretty at #12. Its made a comeback as a Flutter Mane check, while also seeing new purpose in Tera Steel (Flying-resist into Tera Flying Dragonite and Landorus-T) and Tera Dark (surprise Ghost-type resistance.) That being said, I'm choosing A as the place to park it despite that amazing usage, and it mainly boils down to the fact that A+'s Steel-type Heatran not only has a small lead in usage but more so that its high ladder usage is significantly more abundant.
Rise from B+ to A
The rise of the Ting-Lu / Toxapex core has once again given the unkillable wall a new lease on usage. I may be biased since I'm using it myself right now, but despite only sitting at #22 in usage I think it deserves to be in A. It has 9 top 100 finishes, often doesn't need Tera to do its job, and its blind spots are reasonable enough to cover with other high ranking mons. Just to give context: fully invested physical bulk Toxapex survives Jolly Life Orb Chien-Pao's Tera Electric Tera Blast. Then factor in Regenerator and yeah, you probably get the point. Its definitely a more "thinking man's" mon with the power creep going on this generation, but people have started catching on that this thing still slaps.
Rise from B to A-
We've been over the fact that Ting-Lu has stolen its thunder and its only sitting at an above average #36 in terms of rank, but that has not stopped it from continuing to dominate high ladder. It has 5 top 100 finishes from last season! Its clear that people are more likely to spring for Ting-Lu over this, which explains the lower usage, but its still the same dominating Rocks/Yawn wall that terrorizes teams when put in the right setup.
Rise from B to B+
So this one is based mostly on usage, even though Magnezone did have a single top 10 finish (but nothing reported thereafter.) Basically, its maintained a very respectable #26 in usage, which is quite high for something in B. For now, I'm saying B+; I've got to imagine its still a Tera hog, in which case it doesn't really compare to the other Tera hogs in A-.
Drops
Drop from A to A-
I imagine this thing would be a lot better if there weren't so many Ursalunas running around. Simply put, it requires a lot of dedicated support to really get going, on top of being a Tera hog. For the time being, I wouldn't dare drop something with this kind of bulk profile below A-, but other meta-defining forces have simply had greater gravity than Cresselia has.
Drop from A to B+
What's a Thundurus-Therian, and where do I find one? It really wants Tera Flying to make up for its lack of STAB, which means its jockeying heavily with top dogs Dragonite and Landorus-T for that position. Combine that with the fact that we have Zapdos who is much more flexible in its applications and you're left with a frail sweeper that has aggressively mediocre coverage outside of Tera. It simply hasn't lived up to the hype.
