These two mons work amazing together. Dual screens is actually a viable strategy in this meta and is incredibly underused, it can do amazing stuff like completely trolling a rain team with light screen and making your team substantially more bulky on both sides of the spectrum. Dual screens are actually easier to set up than you may think, as it easily is set up on walls, I can often set up multiple screens a game. The movesets are pretty simple, dual screens and light clay for long screens, pyschic for stab and baton pass to escape pursuit. Baton pass also lets you abuse lucarios justified ability to great affect, switching into pursuits to grab a free boost. Lucarios set is standard, bullet punch for if your team stuggles more with terrakion and gengar, or crunch for jellicent (im not a fan of ice punch). Lucario greatly appreciates the screens making setting up much easier and making him actually "bulky". Other members I like to pair with this core is dnite or scarfmence, as dnite becomes a behemoth behind screens and mence can run through teams and be less likely to be revenged, they also have great synergy with lucario, and benefit from espeons magic bounce. If you wanna try something different give this little core a shot!
