Edgeguarding! theres many aspects of edgeguarding, so ill just go over some shizz you'll use most often.. The main thing to know is be maintain an aura of intellegence, while being an animal and ****** your opponent's ****! take advantage of Jigglypuff's mobility, and abuse your opponents second jump, up+b, and lack of God Tier recovery...
After knocking your opponent a good distance off the ledge, its good to edgehog, while continuously dropping off and on, to keep a constant invincibility. I also like to use ledge cancelled sings inorder to distract my opponent whist they recovery.. using sweetspotted ledge pounds is also effective too if you know know to make it seem like you're hitting too high (which causes a sound effect, and a large green smashing animation). This will cause characters like fox/falco/marth/shiek/most everyone to have to go for the stage, putting them at a huge disadvantage. this of course, opens up for ledgehop->Uair, or Pound. at high %'s, it is sometimes more effective to land, and grab them during their lag, or Fair (depending on how high they really are...). If they're close enough for a rest, then you should probably rest.. but don't be reckless.. if you just knocked your opponent off the ledge @ 0% it's probably not a good idea to get a free 25%... just do some Uairs, and rack up the damage...
On Marth, what his recovery.. there's only so much he can do. Most Marths drop below the ledge before recovering on Jiggs, so anticipate this, and Bair them into the stage, and spike them down.. if they go uptop then anticipate their use of SwordDance, and then Bair them into oblivion...
On Fox/Falco, fire can be quite painful, and unnessesary so listen carefully. Hang on the ledge, and then use your invinciblity frames when you Bair/Fair/Nair them.. also don't be afraid to follow them.. they're recoverying... what can they do?? a barrage of Bairs can be your friend here, so use them well good sirs. Dair is also quite effective when you are on the stage, and you want them to stay below it...
On Shiek, get on the ledge!! DO NOT let that ***** grab the ledge. MAKE her teleport on the stage. This is a free rest. Other than that, edgeguarding shiek is pretty tough, but you can hit her during the beggining of the UpB animation, so use her lag as your ally.
On Peach, if the Peach is halfway decent, you're probably not going to get a gimpy kill here... "going out" to get her is often the best stratagy for free damage, but you're probably not going to kill her this way unless you get lucky, and they don't DI.. Much like everyone else just use alot of Bair disjointed hitboxes.
On Falcon, he's pretty easy to edge guard, and unless he knows how to sweet spot the ledge very well a Dsmash spike will almost always end his pathetic existance. If you does infact make it to the ledge, then stay away due to an ease of knee.. that **** is quite painful. Fairs, and Nairs can work wonders here.. just don't be stupid when following him down.. i've seen many'a Falcon saved due to an UpB hug on Jiggs.. Nair should normally out prioritize that shizz so just be smart.
Good Day Sirs.
