I seriously think that you guys are under-estimating jigglypuff.
I honestly think that she is roughly even against pikachu. Yes she is killed at low percent, but she also has a ridiculously cheap and easy 0-kill combo on pikachu.
D-air -> F-throw -> U-air -> U-air -> Rest.
Am I missing something here, or have I just not played any decent pikachu players? D:
Also, fox is one of the easiest characters to combo, seems to fall at the perfect height for everything.
Fox's matchups are only favourable if you don't get hit, or knocked off the edge.
You've got it right, and you're missing something. This is why I suggested we test the puff matchups. Puff has many 0-deaths, which are a huge advantage. But puff's range is soo poor that it is hard to start them (usually), being a huge disadvantage. Since most people have rarely played puffs, as there are not many puff 64 mains, these matchups are relatively unknown. Some matchups are obveous (vs fox and luigi, for example), but others are not.
In terms of the Pika matchup, Pika completely out-ranges Puff. That said, Puff can't approach Pika, or puff will get destroyed. On the flip side, one mistake by pika (missed up-air, etc.) can result in the loss of a stock. Technically, Pika can approach, but as said, one mistake, and good bye.
In terms of combos, Pika can combo puff relatively well, and can kill puff at lower percents. Puff can also combo pika very easily, and can 0-death pika relatively easily. If puff messes up her timing, and Pika has even one frame of non-hitstun, Pika can use up-B to avoid any attack from puff. This can be very useful, since if pika manages to do this as puff is resting, puff misses rest, and pika gets to start his own combos or even just kill puff, depending on the percentages.
In terms of edgeguarding, Pika has an easier time edgeguarding puff than puff on pika. Puff's recovery is fairly predictable, and with continuous hits from pika, puff will exhaust her jumps, and pound will not be enough to bring her back. When puff is edgeguarding Pika, it's basically a guessing game. Pika can go for the ledge or go for the stage. If pika goes for the ledge, D-smash will send him right back off the stage. If pika goes for the stage, he has enough stun for puff to start a combo to death. If puff guesses right, it's usually the end of the stock for pika, and if puff guesses wrong, pika survives.
Overall, though, this is a campy match, where both sides play a "don't get hit" game. This match, unlike most matches, doesn't come down to combo ability, edgeguarding, or anything that would normally determine a matchup result. This matchup, in my opinion, comes down to the mindgames of both characters. Due to the "don't get hit" nature of this matchup, both will have to try to mindgame each other to get that hit on the opponent. Once they get that hit, it will result in lots of damage, or even the loss of a stock. That said, pika usually has an easier time getting that first hit due to his range, meaning he will likely be the one getting that first hit. Also, being predictable will give you an instant loss in this matchup. You should always make your opponent guess what you're going to do, or expect to be mind-gamed into a JD 6-stock (you know what I mean).
In terms of matchup advantage, I would say that Pika would have the advantage in this due to his range and priority, but it would be a slight advantage (i.e. + for pika).
I personally like this matchup as a puff player, as it forces both of us to play a perfect game, and any mistake will be deadly. Either I have not played a very good Pika yet, or this matchup isn't as impossible as people make it out to be. I did a ladder match against Kefit's Pika, and he won 2-1, but every single game came down to last stock, high percentage, virtually next hit wins. Being a ladder match, we both tried our hardest. It was a very even match, and neither one of us made many mistakes at all.
In terms of fox, he's too fast, his lazers hurt, forcing you to approach, and his Bair is perfect for edgeguarding. All his attacks out-range puff. Even if he is one of the easier characters to combo, you will never hit a good fox.
