How to beat delayed wake-ups with Deathstroke:
If you notice your opponent delaying their wake-up to beat out Deathstroke's b1u2, you can alternatively cancel the b1 into sword spin. The reason this works is because sword spin has a 7 frame startup while the 2nd hit of b1u2 is 20 frames. You have to time the b1 as a meaty so that it hits as soon as the opponent can block it. Since you are doing the b1 as early as possible, they won't be able to delay their wake-up. What happens is that the b1 will go through the invincibility frames of the wake-up attack, then the sword spin will stuff the wake-up as soon as the invincibility frames wear off. You can do this with d1 xx sword spin and b22 as well. It's hard to do this midscreen though because you have to have perfect execution and enough frame advantage to get off the d1 or b2 xx sword spin.
