only thing i can say you should change Lucario`s ability to Inner Focus because Dark moves are rare and if you are gonna switch Lucario in on Tyranitar, its gonna use Pursuit anyways. its not like literally every pokemon with a dark move doesnt have a better move for Lucario.
With Inner Focus, Hax Jirachi cant screw with your team after Infernape goes down.
So what if I'd spare him? In my mind it's the certainty in myself that I possess which allows me to have that kind of mercy or compassion. There's no wavering on that point. It's fixed like the stars. The fact is I'm never gonna be killed! So remember this: mercy and compassion are virtues that only the strong are privileged to possess. And I am strong.
