@Crappycola: You play a very high-risk high-reward style fox. Here's what I noticed after watching it (note: this is not a very in-depth critique, and I'm not trying to be mean or anything so don't be offended).
1. Laser more effectively. A lot of your lasering came while you were grounded, which is generally not a good idea. It destroys your mobility and there is (significant enough) lag while you put your gun away.
2. SHDair in front of an opponent (especially on shields) is a huge no-no. It is incredibly easy to punish. This applies to all aerials, but you seemed to over-use Dair more than the others.
3. You attack shields incorrectly. Your spacing needs work. You shouldn't commit so heavily to your assaults. You basically throw moves out and if you miss with it, you get punished. If you space better you will minimize this problem.
4. Too much rolling. You weren't spamming it like a n00b, but there were many situations that it was a bad idea to roll, but the snake was unable to punish you for it.
5. I don't think you know what walking is haha. You sprinted after the snake everywhere. Walking will definitely help you with spacing and will help minimize the damage you take from hits that you could have seen coming more easily had you not been running headlong into them.
6. DI. UAir is the best horizontal momentum cancel. I'm actually not 100% sure if DAir is better than UAir for vertical momentum cancel, but I'm pretty sure it is.
7. I saw you recover with firefox several times. This is usually a pretty bad idea. Illusion is almost always better for recovering.
8. Get more familiar with fox's Out of Shield options. I'm pretty sure I saw you Nair out of shield a time or two, but USmash OoS is pretty beastly given the proper circumstances.
Your item use was okay. Too many people are scared to death of picking up grenades. You were rewarded far too heavily though because this snake player was really bad.
I was glad that you were recovering with rising FAir.
Also, this was a very strange tourney. 6:00 for the match? And in the background I could hear the TO announcing that items and team-attack were the choice of the players O.o
Very legit.
