Decrease the Star KO duration by juuuust a bit

All Star Battle v0.9 should have Sheik, because, while there is a chance that Zelda might change into sheik, it's not very likely to happen.
At least it never happened to me.
It could be on the shadow version of the same stage.

If the Perfect Shield functions like it does in Smash Ultimate, that would be pretty sick.

Don't make the player lose control after defeating Master hand. I actually fell down and died once because I couldn't do anything off stage. Make it more like event 51 or something.

Or, y'know, make Master Hand die faster.

or how about disable blast lines altogether when master hand dies

for event 51, disable blast lines when both hand dies.

Redesign Sky Sanctuary! Or Peach's Castle (Melee).

Hello, haven't been here in a long time hehe

Well, my suggestion is
I think Smash Ultimate's My Music system would work pretty well here, with all stages from a specific franchise using all songs from said franchise
That way some songs that fit incredibly well with both stages of the franchise (Lower Norfair with Phase 8 & Crateria) could be able to play in both and fit perfectly.

Also, some of the songs from the Dev Blogs in 2011 (like Rising Fighting Spirit form Naruto or that great Enemy/Boss Medley from FF4) could be used now given stages would no longer be limited to only 2 songs per stage.

And lastly, some songs from past versions (Power Scale in Namek (0.7) or the old version of Super Metroid Medley) could still be used using this system.

Pluuuuuus, you wouldn't have to compose that many new songs whenever an update hits so work would be overall easier.

I'd love it if music could be added by users using the Import feature in Options, but I feel MyMusic would be already good enough for this to work.

Give his voice from the Kirby anime

Antonio Banderas Meta Knight...

Refrain from putting every non selectable CPU to lv9.
Unexperienced kids play your game, you know?

So, how about different selectable difficulties in event match?

Finally, someone else remembers the Dev Blog tracks. Mega +1 here

Can't forget about Chaos Shrine's old theme

this is not for chars.

Bomb Factory's old theme as well.

I REALLY love the ZUNpet used in that theme.
