I was just about to say Pika and Ganon works pretty well. Pika has a better recovery than Fox (believe it or not, but thats an open debate right there seeing as how there are certain saving potentials in both and yadi yadi, ones uber predictable ones -kinda- predictable blablablablaBOMGGKASFJSDKLF!!!one~1!) and the upsmash from that stupid rat is stronger than even Fox's.
But really, the reason I say that is because my partner plays Pika (at the moment) and its a great team for sure.
Jigs and Ganon? You have gotta watch it, one f-air and Jiggs just might die. Jiggs would be better suited with a fast faller that moves fast on the ground as for good ol grabs. Grab + rest is broken, Oregon has a couple teams that do it, its hard to deal with sometimes.
One of my favorite teams however is Ganon and Link believe it or not. Its not only poetically awesome, but its got great benefits.
Three different projectile attacks that can be directed in great angles. A character that can combo far away as well as close up. (amazing side-dodge,fast smash attacks, great cheap-ko) And if I accidentally hit the courageous b@stard, he doesn't die because he's a heavy weight. (and if done right,[my partner does atleast] you can use a bomb to double-recover and get back from freaking rediculouse depths)
My favorite, Link+Ganondorf
Second Favorite, Pika+Ganondorf
the rest I don't give a crap, really.
edit: oh, tail-spike = ha-ha-ha-hawt!
