It's also interesting to note that Lucario can boost his special attack via Calm Mind. It's possible to run a Sub/CM set, though it's hard to function with only 2 attacks(It's a matter of Hp Ice vs. Shadow Ball/Dark Pulse), while I imagine a 3 attack version using CM and LO could also work, possibly utilizing Vacuum Wave's priority modifier. Lucario has a lot of options not involving SD.
I've been personally testing SubCM Luke on my main team for about 3 days now, and it acutally fits very well with my team. I have a Bulk Up Priority Breloom and a Calm Mind Priority Lucario. Believe me, there's not much that can take double priority sweepers, especially when they're on opposite sides of the attacking spectrum.
For my SubCM Lucario, I run:
Lucario @Leftovers
EVs: 4 Def/252 SpA/252 Spe
Modest Nature
Inner Focus
- Substitute
- Calm Mind
- Vaccum Wave
- Dark Pulse
Yes, this may look like an odd set for Lucario to be running, but it is actually quite deadly. Many of you know that Lucario has billions of resistances due to its amazing typing, and this set lets him abuse them quite well. A good strategy is to Substitute first, because first, it lets you take status, and second, the opponent will still not know which set you are running. It may still be physical, since Lucario can still run a SubPunch set (I know it's not common, but it can work). This means that the opponent might switch to a physical Lucario counter. However, you can CM up during that time. After about 2 Calm Minds, Lucario can take under 25% from most Special Attacking walls, and work like a SubCM Mismagius. The difference between SubCM Lucario and SubCM Mismagius is the physical resistances. Lucario has 5 really good mainly physical resistances, but only 2 big weaknesses.
Yeah, I'm not sure how practical this set actually is, but like I said, it mainly works on my team because of the double priority sweeper combo, which is really potent. I didn't put Infernape on my team for it because it doesn't fit with the synergy of my team, but yeah. This thing has grown on me.
