I think your Young Link is good, but yeah, it needs some work. But don't worry it's still all right. You showed up that doc in all 4 matches, good job. It seemed like you were losing a lot in the first two matches near the beginning, but then you went super sayien and beat him. good job. Anyways, yeah your SHFFL's and wavedashes were descent, but you need to work on your pulse walking for better mindgames. Your spam game was good too, but there was a numerous amount of times where you shouldn't of thrown anything, and doc just caped you. Your grab spamming wasn't totally bad, but needs to be sharpened. You didn't ledge tech enough and you didn't do it very well sometimes, but you still got ok ledge teching in the long run. The two really good things you have with your Young Link in the long run are
1: you mastered a lot of Young Link's combos very well which earned a lot of your victories( no seriously, you just ***** that doc Mario).
2: Your edgegaurding was very well done. You jumped off the edge and naired that doc so he wouldn't get back. NICE!
The two really bad things I noticed are
1: You didn't keep up a very impressive aggressive front in the beginning of your matches. You would kind of run away and just throw a projectile instead of mixing that up with the meat of your sword( which you did later on in the match).
2: Dude, you really need to work on your recovery from the edge. I don't know, overall I didn't see much of an attempt to really make it back to the edge, wheather using your spin attack UNDER the stage or not using your hookshot, it's something you need to work on.
Yeah but other than that, good Young Link. I look forward to seeing your next crewmate battles.
(Well, whad'ya know, I'm a smash journeyman!)
