i like to edgeguard some characters with flamethrower. it sounds stupid, and it looks stupid (and funny), but it works against recoveries that are slower than yours (so you don't end up edgehogging yourself). fox, falco, ness, lucas, zelda, dedede, diddy somewhat. obviously it only works below the ledge, because above it they can just air dodge through it with no fear of running out of recovery room. the benefit is that it's not as easy to avoid as a fair or something. clearly you can just use fair or edgehog in some situations but flamethrower is a nice mixup to toss in that some opponents won't really expect.
