That is very very vague lol
lol sorry i did not know you want details
here what i learn at nec and elso a few new tech baraka players can use in this matchup which would be very useful
1)if the sonya player is throwing rings at you with the mentality that her projectiles recovers fastter force them to stop by doing dash f d3 under the projectile and after you do that you will have two options 1) blade chage if you think she will go for another projectile 2) dash back and spark. .. make sure to back dash so that you are out of the range of her jump in and her ex cartwheel
2) even when she has the better projectile baraka win a projectile war because of his armor on ex blade charge so the sonya player will find hemself having to come after you . . . now as every character in this game who plays against sonya you want to keep yourself out of d4 range by walking back and since baraka has the best back dash in the game you can do it by back dashing as well. . . make sure you are punishing every d4 she wiff that way you will force the sonya player to be closer to you before they do their d4 because they know that if they wiff it they will get punish by a blade charge. . .
3) keep in my that baraka has a 6 frame d3 with fast recover use it as a way to counter her d4 and every now and them do d3xxblade charge because if you hit the hitbox of her d4 with your d3 your oponents finger will still be doing the comand to go into ms and they wont be able to block on time the blade charge
4) now that she is been extract careful about the way she uses her d4 you can start your mind games and 50/50 . . . when she is respecting your blade charge do a quick dash f and do f2blade spin every now and them or dash f b32blade spin or dash f cross up jump
5) do not be afraid to get in but get in and get out
this i one of these matchup that you have to have a lot of experience on the to see it as what it really is. .. a lot of what baraka has to do in this matchup is about mind games and studying your opponent and that is something that you can not put on words
