I've been waiting to see this since you promised on the other thread, lol. Glad to see it showed up somewhere. Unfortunately, I noticed a few more problems here than I did last time. Namely, your edge-guarding, grabs, and ability to score a KO. Don't get me wrong, I'm sure you could destroy me in a ditto lol.
Main edge-guarding issue was that you never pressure him off the map because you're too busy charging AS. I'm not saying that you should be rushing him like crazy but play the edge game a little more and save your charging for neutral position or any other time when you're not giving up a chance to gimp or at least rack some damage.
As far as grabs, you simply don't have them implemented into your game-play. Grabbing makes your opponent feel helpless (psychological damage), slows down the pace (plan offense while pummeling), and makes him more cautious about approaching you. Lucario's throws in particular are invaluable. U and D for starting free Fair combos, F and B for kills.
3:50 was an Fthrow kill, 6:37 was an easy dash-grab opportunity, and 7:04 was a Bthrow kill (these are just the most obvious ones that I went back and picked out from the first match). Recognize these opportunities more. The space immediately in front of and behind you should never be a safe place for your opponent.
Lastly, the KO's. No Toon Link should ever live to 170% against Lucario, imo. You seem to rely heavily on FCAS for kills, and you tend to fire it immediately after you finish charging. Your opponent quickly picked up on that and began countering it (1:10-1:20), turning it into an unreliable killer. Biggest issue was spawning and letting him rack damage on you while he was at high percent. I find that the best way to prevent this is to get the KO and even it back out as soon as possible
Use your invincibility off the spawn to force a commitment and punish it. If that doesn't work, switch to hyper offense or hyper defense. Don't just keep playing as if your stocks are even and settle for another Fair combo. You also need to resist the habit of power-shielding bombs and then sprinting forward into them :/ Best move imo is to sh and grab them out of the air with an AD. This keeps them from bouncing, dodges the other bomb/arrow/boomerang that he always follows the first bomb with, gives you an item, and will teach him not to spam your shield with explosions.
This is easily the longest post I've ever written, but spelling out the analysis helps me as well as you lol. I hope it wasn't too preachy and verbose, I feel like I just finished a high school essay with required citations. Great use of backwards Fair->Nair combos, awesome wavebounces and turnaround shots, and of course, lolsy kill at 9:18. I'd be mad salty after that.
