First thing...for your guys' convenience, I have linked a few MK frame data threads here:
M2K's frame data
JimboCav09's frame data
M2K's frame data is a few months older than Jimbo's frame data, and Jimbo's has a lot more data; however, M2K's data is, well, data from M2K, so I suggest looking into both sets of data and comparing results.
No.
They'll just be like lol Meta out prioritizes Sonic everywhere.
I experienced it on their boards a few days ago, don't bother.
Dude, most Metas are kinda dumb in that way...if you ask me, there is no matchup that isn't worth discussing; more knowledge is always welcome in my book. Hopefully, there are other Metas who agree with me about this and will take this matchup discussion seriously
I main MK and just picked up Sonic a few days ago, so I figure that I might as well give this a shot. Here's my two cents:
~MK's ftilt has good range and is a great spacing tool; also, it should be difficult for Sonic to punish if MK doesn't complete the ftilt. Uncompleted ftilts can also lead into other things, such as dtilts, dsmashes, etc. The third ftilt has a sizable amount of cooldown lag for Sonic to punish with a dash attack or a dash grab or something, though. There isn't too much of a difference in cooldown lag between uncompleted and completed ftilts, but there is a bit less lag from the uncompleted ones.
~MK's dtilts are extremely fast (he can perform 4 dtilts in one second >.>) and hard to punish...especially out of shield. Sonic could dash away and go for a spinshot, but if MK sees this coming, he might try to utilt Sonic if Sonic tries to spinshot over MK into a bair. I just learned how to spinshot the other day, so I don't know a whole lot about its applications, but maybe you guys could come up with ways to use spinshot to go around MK's tilts...?
~The main issue, obviously, is the fact that MK's disjointed hitbox and great range give Sonic a very hard time. Since Sonic's ftilt comes out pretty quick and is one of Sonic's better moves "rangewise," it might be wise to use more ftilts than you might normally use in this matchup to try and give Sonic a spacing tool of his own. MK's ftilt beats out Sonic's ftilt only ever so slightly in range, so the use of Sonic's ftilt to achieve quick spacing might be an option to consider.
~Don't forget that Sonic has amazing running speed...what I mean by this is:
*Sonic can literally
dash away from the tornado (given that Sonic has the space to run). Even if you don't have enough space to completely run from the tornado (which will happen most times), running some distance and shielding after running could save your shield from some of the damage.
*In some situations, dashing away from MK could be used in place of a roll to dodge some of his attacks if you start dashing soon enough. While this wouldn't be happening very often, Sonic could, theoretically, dash away from a completed ftilt, quickly pivot, and dash grab/dash attack for the punish.
I don't have a good amount of matchup experience in this matchup, so all of my comments are based on theory (and some amateur testing in training mode
); in other words, they could and may likely be wrong. However, I thought that trying to contribute would be better than not doing so
Hope that info helps in some way.
