For me I find it effective to utilize dashing over the opponent, keep them moving the stick an thus moving the block direction. You have time to do many things besides his specials off the dash. Some players are intimidated by the 33% chance of what you’ll do which really works in your favor. Sometimes doing nothing is just as good, depends upon your opponent and how you want to approach the match.
OSing is fairly the same as Jago, there aren’t any real specific ones for Shago that I personally can recall, you might look to DaaChronicle, Yiffy Shonryu, or even some of Bass’ clips to see those or ask them directly if they found any unique to Shago.
I will utilize specials on wakeup depending upon the character. You won’t see me tele DK on a riptor, wulf, glacius etc. very often, UNLESS they let me get away with it I will do it. Tele DP is fairly universal, but I don’t like the punish opportunity, test the waters see how protective your opponent is being, one risk is fine depending upon the resources your opponent has. But never forget the more risk you put in the more work you’ll find yourself doing later on.
So more reliably I’d rather utilize normals or dash throw. Dash throw is a risk in that you CAN be punished for doing it, BUT if they tech it you’re back to neutral which is a sacrifice I’ll take any day. Again shago has the SAME normals as Jago, so cl.mk is still a good meaty option an the same rules apply here as with jago, watch meter, watch what type of wakeup options your opponent has. You can catch backdashes with f.hk, an with it being dash cancelable if your opponent blocks it you’ll dash, which is unsafe but you get another chance to keep pressure on the opponent. Sometimes I’ll even backdash after the f.hk, which takes a bit and isn’t a cancel, but gives you space, another risk, just be careful to recognize the options your opponent has.
you can risk a surge fireball, but the startup is so long that you’ll get tossed. my general go to is to keep moving which keeps the opponent moving, which keeps them guessing, which keeps you at an advantage but within risk. have a plan of attack for each character, know what they can safely do on wakeup with and without meter. I’ll abuse thunder all day on wakeup until he gets meter, but i won’t do that for wulf or jago.
