Mainly approaching and his stage-control, but advice on his CQC would be helpful too although I handled that quite well.
Ok so I guess thats why I lost my 1st match I played him on Lylat.
Just take things slowly in that case. Without any video evidence it is again difficult to tell where your exact problem lies, and there's no better advice than just being consciously aware; but I can give you some tips.
As I've said, taking things slowly can give you time to assess the situation. You want to find a way to get in without taking much, if any damage at all. Snake is going to try to keep you out with tilts, grenades, pivot grabs, those sorts of things. Find out what the opponent prefers and work around it accordingly. Take for example Grenade camping. If he's facing you, then you know that you can space attacks so that the worst that will happen is you hit his shield but not his Grenade. If he has his back facing you, you know that you can get a grab in, your wait until he strips/throws the Grenade.
Did I mention it's sometimes just better to reset the situation? It's part of the taking things slowly tidbit I mentioned earlier. Moeoften than not you'll be dying at around 110-130 percent, while Snake will very seldom die before 140 percent. He deals more damage per hit too, which is why taking as little damage as you can is important. Depending on how much momentum you have going, you may want to even avoid trades unless you're really desperate to get that kill; like with him being at 150+ with you being under 70.
Get him in the air every chance you can. While he was ways to get back down on the ground, your best bet is to try and juggle him. Do note that every so often they can toss out a Bair, come down with a grenade, C4, B-Reverse those, and keep you guessing; but you have the advantage if you can chase him.
Try to stay at a certain distance. The point at which his attacks will whiff but if you need to you get get in quickly is what I'm talking about. Being close to him makes you have to deal with his CQC, and being far away will just let him slowly but surely chip at you. Don't ever feel pressured to approach him from a distance, just play reactionary and according to how he behaves depending on where you are.
Don't worry too much about trying to take control of Grenades. They'll always detonate a set time after being pulled, and even if you manage to get control of one Snake can strip you of it with a second pull. First and foremost get them away from you, either by simply running away or if you must get a hold of one, throw it in any direction you don't intend on going; and if you
HAVE to do that just be sure to know when to shield/make the trade count. Being aware of the C4 always helps too. While it's too much to expect anybody to keep a track of the 25 second timer, you can at least know when Snake wants to preemptively set it off because of the audio-cue. If you're not sure of where it is or what to do, just put up your shield or airdodge if you're in the air. If you're feeling real ballsy then you can use your speed to get out of the blastsite before you're caught in it. In the best of cases you can hit Snake with this.
By the way, earlier when I said it's great if you can juggle him, a similar concept applies with offstage pressure. Usually it's best to see if you can force him to recover low, if he's above the stageline feel free to decide whether or not you think it's best at that particular moment to pressure/challenge him that high up. I say do it when he has to recover low because if he goes high, he is given the opportunity to throw out his long-lasting Nair and Dair, and these are attacks you want to avoid getting caught in. There is also the chance that Uair and Bair can catch you and if you're at the right percent in the wrong place, you can die before you really should've, which is why I said sometimes it's better to just let him get low enough so that you can juggle him when he too is low to the ground. Remember though that it's all mix-ups, don't ever let him feel like he's safe; especially being that Sonic can chase him to the ends of the Earth!
That's really all I have to say about this. Good luck.
