Link vs Lucario
Don't underestimate Link just because he's bottom tier, he has a bag full of tricks and skills he can use to make Lucario work for the stock.
First off, Link has three projectiles, arrows, gale boomerang, and bombs. Link's arrows move much faster than Toon links, even faster if Link quickdraws the arrows. If Link is SHing from a distance, he's probably trying to set up a quick drawn arrow. These will clash with BAS until higher percents. Full charged Aura sphere will beat these at any percent. Gale boomerang is a nice projectile that can mess up spacing on the return trip. Be careful of how Lucario uses his Up-B, is Link can predict this he might be able to gale guard him, using the gale boomerang to bounce off the stage and drag you away. Bas won't beat this til very high percentages, Full charged aura spheres will beat this out at high percents. Bombs are Links most versatile projectiles, the amount of techs around them is numerous. I'd advice reading this thread
here believe it or not these techs around them aren't horribly situational and have many applications they can be used for. Bombs will cancel out any form of Aura sphere.
Other than projetiles, Link can also stand still with his shield up to block the aura sphere. This won't happen often as Lucario shouldn't spam fully charged aura spheres anyways.
Link has a good move in the form of Zair. It has two hit boxes and can space well to keep Lucario away. Zair also has some nice follow-ups some of which are kill moves if your not careful. Link's DAC covers long distance and can surprise a lot of people.
Link's main forms of Killing are Dair, Usmash, Utilt, Ftilt, Fsmash, Dsmash. Thats a lot of kill moves, and all of these kill very well, the main ones to watch out for are Dair, Usmash, Utilt, and Dsmash due to Lucario having trouble with getting killed vertically. Don't use Lucario's Usmash on Link's Dair or Lucario's Dair on Usmash, Link's moves have more range. This can be applied to other moves such as Link's Fair and Zair.
Sounds like Link is awesome, well not quite. While Link has a a nice amount of moves he still has problems. Lucario can combo and string moves together at low percentages, this sucks for Link. Link is quite heavy, and as a result is susceptible to being juggled at low %. Link is also quite slow when it comes to start up and cool down of moves. Most of his attacks aren't safe on block against a majority of the cast. You can shield and punish a good bulk of his moves, Link relies on using his projectiles in conjunction with his moves to get his kills.
The main problem Link faces is his terribad recovery, he has the worst recovery in the game. While Link has the potential to live as long as Snake can due to his good momentum canceling, DI, and heaviness, this is all useless if he gets gimped. Lucario can Dair, chuck an aura sphere, Fair, bair, etc. While it's isn't as easy as it sounds, Lucario has quite a few options to gimp Link.
For stages, If I were Link I'd want to go to Norfair, Battlefield, or Final destination. Norfair is Link's best stage, it helps his camp game, makes it easier for him to get kills, and occasionally helps his bad recovery with lava, if I were to ban a stage against a Link I'd ban this one over the others. Battlefield and Final destination are recommended due to how it helps Link with his camping a bit more.
If I were Lucario I'd take Link to Frigate, he has a horrible recover, combine that with this stage and no grabbing on some sides and you get a very happy Lucario. Japes helps Link's camping a bit, but it helps Lucario more with the gimping he can do combined with the high ceiling.
Due to Link's bad recovery and Lucario's abilty to juggle him I'd rate this, 60:40 Lucario.
Wait, are we sure that Link can't break out of FPCG for some odd reason? Because you can normally break out of it.
Link can break out of it like everyone else can.
zair is a good spacing tool, iirc, and he can still do it if he's holding a bomb (AD -> zair)
He can also hold a bomb while doing a Fsmash or Usmash.
This was stuff I picked up from when I was experimenting with Link, although some of it might be outdated here and there lol. Someone who plays link (like Red Ryu) clarify?
Here is a list of Link's techs, he's got quite a few of them
Edit: for the record, Misadventures of Flapjack imo is kinda dumb lol, I miss the old Cartoon Network with Toonami and such T.T
I miss old Toonami...
