Sorry bro, I’m afraid you’ll have to work to get better with Sakura like the rest of us.
There are no best in game combo’s. There are full damage combo’s, combo’s that end with better knockdown situations, no meter combo’s.
Same goes for frametraps, it depends on the space, the character(how fast is their cr.lk/cr.lp/cr.mp, etc, what range does it have?), your throw range and the opponents throw range.
But to help you a little bit here is a list Robot Makoto posted in the Q&A section
If you don’t have time to go through threads, stop making them lol.
Just ask questions in Sakura Q&A.
