Great advice.

- Use more shffl'd attacks in general, especially NAir, FAir, sh double FAir, and (this is personal preference) FAir -> UAir in the same short-hop (it's easiest to do the UAir with the C-stick).
- Don't rely on throw -> dash attack as much.
- Learn how to use UTilt in alternate directions (UTilt to the left -> UTilt to the right); don't use USmash as much.
- (Also personal preference) You can use Dolphin Slash or Reverse Dolphin Slash in close-ranged combat for a surprise KO at high %'s.
- You didn't miss it too many times, but perfect l-canceling DAir.
Ganondorf
- L-CANCEL!
- Learn how to recover; use Wizard's Boot -> jump as many times as possible when recovering.
- Don't spike with Wizard's Boot if it's unnecessary; you can suicide from it (2:29).
- Use UAir and DAir more.
Falco
- Learn how to pillar.
- Learn how to shl.
Samus
Meh, I haven't used Samus in ages and I don't know how to play a good one, so I have nothing to criticize about. Also, I HIGHLY doubt that was actually Zelgadis. You can see my reasoning in my YouTube comment.
