So, excellent news everyone! After the tragic loss of my old 3DS Smash in December, I have claimed a new one for my birthday! And a New 3DS! And a Megaman Amiibo!
Although the Amiibo named Jmpnshtman is now wiping he floor with my face, I want to start challenging people againa nd unlocking customs all over again! Hope you guys are ready!
Well that's the good thing about this game - the only consistent thing about tier lists right now is a monkey and three ladies in blue are up top - and even then one tournament goer thinks Diddy's only top because the metagame hasn't been learnt out yet.
(His infamous combo-ing ability will start to break once you properly understand how the games DI works, apparently.)
You are all wrong, it is clearly Snoopy (Hey, I already went for the "Lucy van Pelt" joke when Moon asked this same question, so no point repeating).
AAAAUUUUGGGHHHH!!!!Someone 3 stocked me with Sonic earlier today and then then just now I went against them again and they had this to say when he recognized me
"You are the one with the scary Ninja, lol"
... I don't see how being destroyed without even managing to take out one of your lives makes my Greninja scary to fight. But okay.
Speaking of Greninja, here's something I found that you might try on For Glory:
D-Air, D-Air, Fast-fall, Substitute. After the second hit, your opponent's position will have shifted too much to land a third Dair, so fast falling will make it look like a third strike, when you are actually preparing for a counter.
This is all in theory, so I haven't tested it yet. And I agree, Greninja is a lot of fun to play with.

I had an epic moment with Lucina against my friend and my Kirby and Fox Amiibos:
Myself, the friend as Little Mac, and Kirby (IIRC) were on one life. I get the Smash Ball, and use Lucina's Critical Hit. I get both Kirby and Mac at the same time, basically getting a Double KO.
AAAAUUUUGGGHHHH!!!!
