Lol now that we have no more Kami...
I personally run 3221 for all match ups except doubles. Piercing's knockback is stupidly high and there's also the fact that at mid-high aura it actually has deceptive hitboxes. If only advancing force palm had the PM force palm aerial thing, would love it to pieces. But even though it has poorer killing power than force palm, its utility is completely different. As it allows you to grab from further away, alternating this with dash grabs, standing grabs and pivot grabs leaves your grab range ambiguous at all times, forcing your opponent to forgo their shield once you reach dashing force palm range. If they shield, they get force palmed, if they try and advance, retreating pivot grab. Mixing all of these with run up shield will also completely mess with their shielding habits. If they start trying to attack instead of shield to beat out grabs, run up shield allows you to power shield the attack and standing grab.
I prefer ride the wind for its ease of recovery, seriously, once you get tricky with RTW at high percentages, you don't need to worry about getting challenged. I've done half loops away from the stage into an S to give myself momentum to ledge snap. Once you pull that off, unless they're like... villager or something, everyone's gonna just accept you're recovering and not risk losing a stock.
I mentioned screwing with shielding habits earlier. Once your opponent gets grabbed at mid percent, forward throw is a godsend. It's mad knockback pushes them off stage at high aura and leads to piercing AS. Even mid charge AS at this point can combo to get the gimps, and if they recover low, run-off dair covers perfectly. It forces them to recover high, which in most cases leaves them prey to up smash with the read, or a reactionary AFP which launches them diagonally if it doesn't kill, so the situation resets. This custom set has quickly caused Lucario to jump to my highest number of 3 stocking characters.
For doubles I run 2221 with my brother's villager to abuse Mahvel Sph3re. I'm very capable of stock tanking with characters like Ike, so lucario is a cake walk. Mahvel Sph3re only works if lucario lives to high percents. Doing so gives you the stronger sphere which you can throw out, have it hit, and then get pocketed. As I learned in winner's finals. Sandwiching an opponent with Snaring is incredibly brutal. Or throwing out an AS to then force them into villager's AS is ridiculous. The two spheres can combo into each other. I don't have footage of the 3 stocks atm (3ds, saving clips for crew trailer anyway), but you can see how we utilise Villager/Lucario on our channel on Wednesday when the doubles footage comes out

I think the lucario in this is @
Loota
so props to him for this if that's the case.
Edit, my bad, the lucario was Forre, villager was Spike
