For the first match, you used bair too much. It's a great move, but it's one of your KO moves, so I wouldn't use it so often. Your utilt usage was great, but I saw no ftilt or dtilt. Ftilt doesn't always come in handy, but dtilt does. At the beginning, you used FC to stop your knockback, which, while it works, could lead to SD's. I would suggest using a stone. Speaking of which, you used stone in all the wrong places. You don't use it while onstage most of the time, you use it to edgeguard. For your aerials. you basically used mostly bair, and a little Uair. You need to use your other aerials more often. You should learn how to use aerial hammer for hits. It would be a better KO move than the Up-smash you tried to use (sorry, it just doesn't work for Ike)
. You also need to use more throws. It also seemed like you remembered to use some moves at some points (bair in the beginning) and then completely forgot about them. If you wanna see aerial hammer, brawl me. I use them really well
. Finally, is the Gonzo Combo the only combo you know?
Mostly the same was true for the second match, though you did hit once with an aerial hammer. When you used fast-falled fairs, I would've used aerial hammers, but perhaps that's just my playstyle.
Another thing I noticed it that you don't use inhale at all.
On the positive outlook, you're a pretty good Kirby. You know how to use that bair, but you seem to have taken a bit too much to Gonzo, and you tried a few things that didn't work (your stone).
If you PM me, I'll brawl you, and I can give better advice then.
