You don't need restand when you can break armor with the balls, f2 2+4 => EX balls / 2nd ball. There you can do at most a 13f starter it will break any armor except Goro. Timing is as soon as you finished.
As for corner combo to hit, yes sadly you only have NJP ~ f2 ~ (f2) ~ b14
Pretty sad they didn't move the d3 on block frames, it's slower than d1, the frame trap is weak against armor and also has same on block frames than d1 which has better on hit advantages. Only difference is the low hit, which doesn't help because you can't be sure 100% you'll break guard with it and then make good use of your advantage (6 frames is reaaaally fast)
