-Lucario has precognition and analytical prediction (AP is only via Detect), he can see when the next attack is coming and dodge it by reading the opponent's aura and he can also detect the next attack and casually dodge it.
Kamen Rider Calibur have the ability to precog countless/nigh infinite timelines for the user to see. Basically allow them to read through every move that opponent could do. Saber, someone that Slash beat despite the 9x or so AP disadvantages through sheer skill, stomp Calibur at the end of the first arc.
Lucario is generally a pokemon who can fight against genius level characters such as Machamps who have mastered all martial arts
For a gist on the skill level of Saber Rider.
Lucario can boost himself up to 4 times when it comes to power and speed, meaning that he is already beyond the territory of blitzing. Additionally he can use Extreme speed which is an attack which makes him move even faster and basically blitz opponents, so if he gets 4x faster than that would be blitzing an already blitz speed. Additionally his attacks can leave afterimages
Both speed blitz and after images are main gimmicks of both Espada and Kenzan. Extreme speed only last for a brief moment and Slash stamina combined with Low-Mid mean that he'll hang on. He can also make a forcefield out of a swing of his sword as well.
-He can use screech to lower the opponents defense up to 4x what it is. 120/3 is 40 so he could nerf his defenses to 10 megatons.
And Slash constantly get stronger the fight goes on via Suzune ability to constantly amp itself as it make more noise, and belived me, it make a lot of noise. Usually enough to overpowered opponent who overpowered him throughout the fight. Not only that, he could amp himself even further by using Bremen No Rockband which is also another massive boost to his AP even further than before, good enough to stomp peep who can overpowered him as well.
He can use laser focus which besides giving him a perfect guaranteed hit on the opponent, let's him land a critical hit which is 1.5x stronger.
Guaranteed hit doesn't mean it won't get block, considering Slash skill and forcefield I think it won't do much.
He has counter which returns an attack's power back at the opponent so if he gets struck with 40 gt then he can return 80
He can, if it'll hit. Slash is able to gracefully parry attacks that has AP waaaay higher than he himself should by the fact that he just shrug off stuff like King of Arthur attack which should be, at least, 3 times stronger than himself.
He can use Me First which can steal an opponent's attack, Lucario ends up using it first and it is stronger than the original attack
Most thing he'll get is just Slash shooting or slashing at him which isn't much. Unless he used it on a finisher.
Above all else, Lucario have something that he cannot blitz through. Bremen's hypnosis which basically put Lucario into a state of constant confusion plus massive AoE around him which make dodging useless.
