So. Meta Knight was nerfed a while ago, in patch 1.1.5. This took 1% off of his U-air, added and SDI multiplier of 1.5, and gave it a slightly lower angle. I've been experimenting with this move, and added what I found into the guide.
-Dash Attack-->4 or 5x U-air-->Up B still works and KOs, but at slightly higher %s than before. You will need to be able to move more, as well as read the opponent's DI.
-Honestly, everything else is pretty much the same.
I've also added more little details to almost all the sections, especially the playstyle, where I put more detail on the neutral. Please tell me if I missed anything, and have a good day.
