So, countering this blockstring via armored reversals is heavily stringent on when Baraka calls the heli-chopper assist.
If Baraka calls Cyrax right when the first hit of df+2 connects, it's damn near a true blockstring. I believe the only armored reversals that beat this are Johnny, Ashrah and Nitara. I believe that at this timing, Baraka is also safe on block, though he's minus; he can't continue pressure.
If Baraka calls Cyrax after the first hit of df+2, then almost every armored reversal will win. Raiden, Liu Kang and Tanya will hit Baraka but then get hit by Cyrax. Also, Reptile, Baraka and Reiko will slip behind Baraka once you armor through df+2's gap. At this timing, Baraka is safe on block and can be plus enough to continue pressure, depending on if he times it right at the second hit or third hit of df+2.
If Baraka calls Cyrax right when he executes df+2, then only Ashrah can armor through it, but Baraka will be unsafe on block. So, there's no need to armored reversal.
I'll see if I can make a video that goes into more detail about this.
