Dude. You probably play the best defensive Link I have ever seen. You take advantage of all his defensive options (especially in the Samus fight), which is good. I think I might consider using some aspects of your meta for the ZSS MU. If you were going for being a total troll with Link online, you get a solid 10/10.
The only thing I don't like though is that you severely limit many of his other options and reduce yourself to spamming projectiles and recovering low with spin attack. A really good competitive player would see this and find a way to punish you hard for it. They also won't run into all your attacks like the other players did in your matches. You play your Link with what I call "Iron Boots," meaning you play him solely on the ground and never leave the stage. Basically, you play like Little Mac, and that only takes Link so far. You should use some of his aerials more, take advantage of more ATs, use Zair (clawshot in the air). Open yourself up to the many other things Link can do. He's a very versatile character with lots of potential, so experiment with his many options. DO MORE WITH LINK.
Btw,
