5B is +1 on block. You can keep doing 5B dash 5A unless the opponent knows to IB it. For certain characters, they can't do anything except DP even if they IB it because they don't have anything that outspeeds your 5A (Yukiko, Labrys, Teddie etc.). 5A 5AA and 2B are jump cancellable. And 5D 5DD will allow you reset pressure if the opponent respects it.
