Get a lead and then platform camp. Sheik really cant do much if you stay on the top platform on BF except chase you with aerials. Grab the ledge whenever she is trying to recover to force her to use vanish. I made a post on this matchup a whil back let me try to find it.
Just a few things that you guys might know and that you might not that you probably want to take a look at.
-I know Ganon players love to go offfstage and try for spikes and tipman spikes, but in the Sheik matchup it gets really simple.
All you need to do is grab the ledge. Every single time Sheik is trying to get back onto the stage grab the ledge and take away her option of using the tether. At first glance it looks like Sheiks recovery is pretty good, but if she is ever forced to use Vanish and she is forced to land on the stage it's a free ledge drop uair, fair, or if your quick enough a normal getup onto the stage into an dtilt, ftilt, or fsmash.
-Her ftilt is a beast in this matchup obviously. You all are aware of escaping it at early percentages with down DI and then getting up your shield. Experienced Sheik players will ftilt a couple of times at early percentages and then immediately go into a dsmash, jabs, or a grab. After you DI down and then get your shield up....immediately roll backwards.
At mid percentages it really is just a matter of not getting hit with her ftilt. If you are ever in a position where you are in your shield and Sheik is just ftilting away, full hop and then go from there......anything that Sheik can do to you in the air is nothing compared to what ftilt will do to you. Even on a powershield there is little you can do if the Sheik player buffers her ftilt correctly.
One thing i've found to be semi-reliable as i've played as Ganon in this matchup is to powershield, SH a bit out of range from her ftilt, and then catch her with an aerial Gerudo. This is extremely risky if the Sheik player happens to spotdodge it however....so only use it as a mixup every once in a while.
If you spotdodge an ftilt, do not attemp a jab or dtilt or any other possible close range option you have. Sheiks jab, ftilt, and utilt will outspeed anything in your moveset and you will find yourself in a deadly frame trap. Your best option would be to roll or jump away and reset your spacing.
In fact I would recommend spotdodging an awful lot in this matchup because her only real threat to beat a spotdodge on the ground would be her utilt. If you are facing an ftilt crazy Sheik.....spotdodging can be a life saver.
- Her grab game isn't amazing, but she is quick enough to make it seem that way at times. If your in the habit of immediately airdodging after being thrown, you will easily get hit by Sheiks nair or bair.
Probably her best and most used throw is going to be fthrow. Most average Sheik players will love to fthrow and immediately SH fair to try to knock you offstage. This is easily avoidable if you DI down and away on her fthrow. The better Sheik players, however, will fthrow and walk into a shield>utilt>ftilt on Ganon.........something you should be very aware of.
She does have some nasty tricks on Ganon out of a ground release since he is in perfect range for an ftilt or a dash grab. Once again if you ever suspect a grab release, a spotdodge is your best friend and then immediately get the hell out of there. I personally love to release to a needle storm and if it's shielded then I regrab.
- Dair is pretty useless against Sheik. Her utilt easily beats it and if you get hit with it your in for a lot of trouble because it leads directly into ftilt. You can't really use dair OoS either because Sheik has very few attacks that are laggy and Sheik doesn't really need them in the Ganon matchup(usmash, fsmash, dsmash).
You do not want to be close to Sheik. Dtilt is still punishable on block by Sheik...but at least your not getting hit with an ftilt.
I've found that ftilt is really good in the Sheik matchup because you can easily setup up for some edgeguards which is honestly one of the few things you have going for you in this matchup.
- A lot of Sheik users(myself included), will love to praise the chain and all of its glory. It is true that technically with perfect use Ganon can not do a **** thing.....but I found a small trick.
It is extremely hard for me to maintain chain coverage behind myself when protecting from the front and it takes a little while for me to transition behind me if my opponent lands behind the chain. Full hop over the chain, land behind Sheik, and when Sheik moves the chain behind quickly SH and wizkick onto the top of Sheik. This is really one of the only ways I have ever been able to sneak past the chain and its devilry.
Ya so those are just a few things that you guys might care about....let me know if any of it is useful. I have a few more tidbits but thats all I can think of right now.
