So OU really doesn't care about monthly drops / rises at all, because everything can be used outside of the obvious banning to Ubers. However, I did find it interesting that Gallade dropped back to UU (Mega Gallade was already in BL, but same difference not in OU anymore). Thought this was interesting from all the hype it got, with some even pushing for Gallade to go to S rank near the beginning. Gallade's usage has also been cut in half since November / December. Very interesting because it did look like the complete package, but ended up being rather easy to play around and check. Also a great example of something with limited pool hard counters (just Sableye and Unaware Clef iirc) but a large pool of checks and RKers. This isn't even some usage =/= viability thing either because Gallade has fallen off quite a bit in the VR thread as well. Can't even recall if a Mega went through a similar drop off in the early XY stages, maybe Mega TTar?
The other interesting trend is the extreme rise in Manaphy and Torn-T. Manaphy has nearly doubled in usage since February, and Torn-T has almost doubled in usage since March (3.5 -> 6.89, 4.66 -> 7.92 respectively). Manaphy is pretty self explanatory, it is puts a tremendous amount of pressure on defensive teams and balanced cores because of how ridiculous a boosting move like Tail Glow is. Torn-T is more interesting. Is that a sign that Landorus is a problem? I think part of the usage spike might be Torn-T's great speed tier post-Gren ban. Another part is just how many tools it has to pressure common checks. Hurricane, Superpower, Heat Wave, Focus Blast, and Knock Off are already a lot of options, and that's before you throw in utility options like Taunt and U-Turn. Really splashable and easy to fit into teams right now.
