How do you call a fast mid knive poor? Yes, bd1 has range but I'll just zone you out with knives and d4 ex knives into pressure. Any ways. Cyber b2 is a great way to punish whiffing in conjuntion of his d4. Cyber is safer and actually beats CT in a mirror macth.
F4 is a far better whiff punisher. By a lot. Cyber isn't safer simply because you keep repeating it. One look at the frame data is all you need.
B13,1+3 is punishable, laser is punishable and B1 is -8.
Definitely not safer.
B2 can be interrupted by basically anything when it isn't being nuetral jumped.
Cyber's MB Knives guarantee nothing on block, not even a poke, compared to the far greater + frames Cutthroat gets off EX Buff cancels.
The mid knife is poor because it loses in trades with most other projectiles, (example: A-List Johnny Cage can out-zone Cyber simply because his projectile will always trade in his favor) it's also poor as far as chip damage is concerned. There's really nothing to fear from blocking a Cyber knife and working your way in.
Cyber doesn't win the mirror. At best, it's probably even despite Cutthroat massively out-damaging Cyber. It's hilarious, even Cutthroat's knives deal more damage on hit than Cyber's.
