I'll throw something in here.
Zelda is ultra defensive, and we all know that. You must abuse your TP smashes, abuse Dtilt, and her range effectively. There was a time when I almost never jumped when using Zelda because why use a risky aerial when I have a safe smash.
Zelda destroys the low tier characters, does ok in the mid tiers, and presents unique matchups to a lot of the high tiers. I say unique because she presents approach problems. MK's cannot use glide approach, dash approach or even tornado if you time stuff right. They have to actually think, use their quickness, and bait you (which is Zelda's game only without the quickness).
Zelda is a tough character to play, but she is far from the worst in the game. Even in Brawl+ she is mid-tier at best because her move set is just that bad even when buffed.
Jab is a good anti-air move.
F-Smash is a pretty safe smash, great range, and tp.
U-Smash is the best smash in the game. Period.
D-Smash is a great killing smash that should be used for the spacies, link, ganon, etc
U-Tilt needs d-tilt setup and is more powerful than U-smash in kill percents
F-Tilt is stupid
D-Tilt is amazing. Period.
LK's are ok. When they flub, it sucks for you.
D-Air is a fantastic aerial. Flub spike is like a footstool and sweetspot is 4th strongest in the game. And it is high priority/disjointedness.
N-Air is meh but useful.
U-Air needs dins setup.
Naryu's sucks... and so does love jumping.
Dins is a pressure aerial when they are off stage or strong distance.
Dash attack is 5 frame goodness but highly shield punished.
All Grabs and Throws suck though U-throw to U-air does work (at least on fast fallers).
I've been playing Zelda for a year and a half. I can't play any other character in regular brawl, and I can only play 2 other characters in Brawl+ (none of which are Sheik). I love her play style, and I just have gotten a lot better with her. Her defense is almost unrivaled. She has a projectile camping weakness, and if she gets timed out, it's because Brawl was built to do that.
If someone times you out, rip out their controller cord then strangle them with it. Then, when they are gasping for air, tell them you are timing them out and they should just quit. See if they ever time you out again. (I know, mean, but this is Brawl
)
In the end, Zelda is lower middle tier. Her metagame is slow to develop because there are just a handful who play her seriously. She has a simple, straight forward game because that's how she was programmed. To play her at a high level, you have to make smart decisions, space correctly, and abuse her abilities. You might be able to say that about any character, but with Zelda, it is extremely important to be technically sound. She does not have the ability to be played sloppy and win.
I have no idea if I summed up the post or not, but I am done typing for now.
