^ way to kill my buildup :/
All this situational talk is pretty pointless :/. From my games with sonic players I notice it often plays out with the Sonic trying to bait GW into commiting to a move(Dtilt for example) with spin cancels and then grabbing him dthrowing and techchasing or uthrow and punishing a dair reaction or jump with bair or uair. If Sonic hit's GW's shield with spincharge they usually double jump up-b to dair, which is actually pretty safe if you have the key [1] (spring?) covering your landing considering Sonic has no lag and can just run right when he lands. I also see a lot of ASC to grabs going to because GW's like to sit in their shield and try and punish the spindash with uair or up-B. GW's Dtilt is useful when the sonic isn't running and you are in a positional advantage on the stage. You can keep approaching slowly with it or [2] retreat with fair depending on their reaction. It's mainly used to bait spindashes however which I personally like to run up to and make them hit my shield but throw off their timing since I'm closer then they anticipated and get them with nair or uair/up-b. When they dair down after a spring Sonic players almost always keep running the direction they are facing so it's good to overshoot your punish as it often connects this way.
[insert truth]
65-35 or 60-40 in GW's favor.
[1] Spring*, not key?
Well, it might be safe, if the spring is blocking your walk path. Some unwise and punishable ones I've seen usually involve Sonic dropping the spring overhead and D-airing the way they're facing, which is simple to punish (shield the spring, punish the landing).
[2] F-air's landing lag is punishable, but if you mean a rising FH or something 'finished'/ac'd then okay.
Anyway, I'm tired and Hylian went ahead and started it, so I'll spoil it.
My #6 was specifically mentioned to be on-stage and in front of GAW, because that's the situation that would occur if Sonic got a grab in and did U-throw/F-throw (more easily, F-throw). If you D-air and we walk out of range, you're grabbed, or maybe even foxtrot F-smashed. If you F-air from anywhere higher than say, FH height, Sonic can run under and pull a rising aerial on you. If you airdodge, we land alot of kills or get damage from ASC combos/tilts/more grabs due to airdodges
The question about GAW/Sonic's top speeds is because Sonic will not always be doing a D-air after spring. This would go with edgeguarding, because if Sonic has faster max airspeed than GAW's top speed, it makes it harder for GAW to punish a non D-air spring recovery.
D-throw doesn't lead to techchase. DI it up and his followups are dead.
DI towards him when he Up-throws, he can't hit you with anything either.
You're horribly outdated on this. We've been dealing with and punishing/playing with people who do upwards DI for a long time now.
DI downwards, standing tech. It's all the rage now.
Free followup. GUARANTEED.
