Yea, I read that topic a few days ago. How else can I techchase with Sonic then?
You still can XD.
1- matchup inexperience. You're still sure to be able to D-throw some people, realistically. The DI-up+airdodge/double jump method, which was previously thought to be the best choice, is still pretty common.
2- Against people who know about it, they may try to get away with things that really won't catch Sonic before he can shield, none of which I will name. It sets up for a counter-punishment, especially at higher %'s. But really, for pretty much every character, the best they can pull is a jab combo.
D-throw is still useful by the edge of stages though, especially if your opponent is at a higher % that sends a little further than normal. Can you see it? They think they're gonna tech the floor, but get sent past the edge and airdodge, while you recover and set up a gimp
What I normally do is jump around myself, out of the way of their spaced approaches if need be. Sonic has good air speed so movement wise, it's ok and if things get dangerous, you can always Spring out the way. Eventually, your opponent will run out of multiple jumps/space on the stage and they'll be forced to land/get back onto the stage. When that happens, I either Up Smash/Up Tilt or shield an incoming downward attack and attempt to punish
Simply put, my advice would be that you want to bait them into either getting them above you for an Up Smash/Up Tilt/Uair or make them try and get you with a ground attack so you can punish. They can spam spaced approaches all they like if you don't run into them and continually get closer and closer. Eventually, they'll have to do something else
...Sorry that sounds/looks really crap :/ What do you think Tenki?
Well, my main issue is that they don't use all their jumps. For the 4+ jumpers, they may only use 3, or 4, land if I don't approach, then do it again. Things like SH D-air are kind of cruel shield pressure, though I guess it may be possible to FH F-air or something out of shield.
Oh well. I just thought of that lol. I'll try it next time and see how it works out.
