Meteor Mash on Lucario might be able to push it into UU, and will make Mega Lucario more powerful than it already was
Kommo-O I see moving into BL/OU. While the abundance of fairies is scary, if it can switch it, and unleash its Z-move, it can set itself up very nicely to sweep. Drain Punch and Close Combat make it A LOT more viable, combined with the elemental punches. Even if choosing not to run the Z-move, it still has good bulk and access to Dragon Dance, so Kommo-O will likely move up a few tiers.
Ribombee I see moving up into RU at the least. With its insane speed, and access to Sticky Web now, it should certainly see more usage if only to lay the hazard.
Accelgor I can see moving into RU or BL3. With access now to Toxic Spikes, combined with its insane speed, it would do a good job of setting up hazards.
Lurantis I see moving up into NU or even RU. With access to both Superpower and Leaf Storm, combined with Contrary, it can spam both moves while subsequently increasing its own power, making very little that can actually switch into it.
Incineroar I see moving into RU. With access to Drain Punch and Knock Off, combined with its good bulk, good attack, and inability to be burned (and eventually his HA), Incineroar will be a force to be reckoned with.
Kartana, while not moving tiers, should move up even high in the OU tier, given it now has access to Knock Off, a very nice go to move for any pokemon.
Bewear might end up creeping into UU, as it now has a very good move in the form of Drain Punch to recovery and keep its incredible bulk alive. Combined with Swords Dance, and Bewear can OHKO pokemon to recover.
Buzzwole I can see jumping back into OU, as it now has access to Superpower and Drain Punch, which can help it keep its bulk up, while dealing damage and not slowing it down.
Linoone getting ExtremeSpeed as an eggmove gives it options for a lot more sets, and likely will make it rise in viability.
