I disagree, even if we dont like her(him), its a popular pokemon since the original and is very unique in SSB + An original 12. Mewtwo definitely needs to come back, and Even though i do agree Zoroark+Blaziken are very popular pokemon (especially Blaziken cuz he's the most popular starter outside the original 3) Jigglypuff is huge. This is thankz to the Anime, and Japanese love her(him)

Jigglypuff isn't very popular in Smash Bros. itself, or in any capacity outside of Japan. I don't use Jifflypuff, and have never seen anyone else use it. I also don't see why Jigglypuff should be "sacred", just because its an original. As for the anime, Jigglypuff hasn't been a staple in over a decade and isn't important to Pokemon overall.

i want 6 slots for pokemon
i would like 6 slots for all big IPs like zelda and mario.

my zelda dream team: SS link, OoT Zelda/sheik, TP ganondorf, ghirahim(and demise in the smashball), majoras young link(+deku,zora and goron, deiti fiery mask as smashball), and tetra/toon zelda.

Jigglypuff is the most competitive character in SSBM tournies outside of Fox/Falco! She ranks in top 4 most used character in that game. 

Even if she isnt as big as she once were, its still one of the most known (easily top 5) pokemon. She isnt going away, She is also by far the best aerial character in ssb! just saying!!!

Okay, I'll settle, Jigglypuff can stay but I want more Pokemon characters. The more the merrier, that's what Smash Bros. is all about.

I'll admit wen ssbm came out i was just like you lol  

This dream is so beautiful, tears are forming in my eyes. If this happened I'd cry a river of joy.

@bolded This is so genius! I never thought of that!

It would be a bit weird to have toon zelda without toon link though.

If LoZ gets anyone new, it will be one character imo. With Sheik+Ganon thats already 5. Young Link was obvious from his MM appearance, im surprised you haven't seen that o.O  People been screaming that since before even SSBB came out :)

Yeah.

And about MM link, i already though about all b moves.

down+b is reserved to mask change.

link: b=arrow, side+b=bomb(drawn and throw in a only move)(no bumerang, is not a item in MM), b+up=sword spin.

deku: b= deku nut, side+b=bubble, up+b=flower catpult, in the air you can float(like peach) and press b to throw deku nuts.

goron: b=rolling(like jigglypuff's rollout), side+b=energized punch, up+b=curled jump that cause a local earthquake 

zora:b=bio-eletric barrier(could work like zelda's nayru love), side+b = fin bumerang, up+b= jump backflip.
