I did some testing on Ivy's WP 6B+K 2_8...
Assuming that NM is on the 1P side and Ivy on the 2P side:
1. NM can step WP 6B+K to both sides, although it is far easier to step it to his right... that is step using 2. Interestingly, if they use 6B+K 2 and you step using 8, the second part, where Ivy's sword flicks in the 2 direction will still hit you...
2. NM can 8WR to his right to avoid WP 6B+K. That is, holding 1, 2, or 3 will allow you to side walk WP 6B+K. While side walking to his right NM can still guard against either the 2 or 8 follow up to WP 6B+K. However he cannot sidewalk it to his left. That is, you cannot hold 7, 8, or 9 to avoid WP 6B+K. I have yet to test this in match play but holding 3 seems to be a better option as it moves you closer at the same time.
3. If you block the both hits of 6B+K 2_8 the push back is enormous. NM cannot punish after blocking both hits unless he was extremely close to Ivy to begin with. However, if you side step or 8WR the first hit and block only the second hit then NM can almost always punish with 6B:B. Only at the tip range of WP 6B+K 2_8 is 6B:B an inconsistent punisher due to occasional whiffing. For some reason, though, I seem to have a lot of difficulty getting the JF to come out at tip... does anyone else have this problem? 33B can also be used to punish WP 6B+K 2_8 if only the second hit is blocked. However this is very range dependent. At mid-far block, the 33B will whiff. At close block of the second hit of WP 6B+K 2_8, you can also punish using agA or iagA.
4. WP 6B+K 2_8 has a weird dead zone close to Ivy. If you evade the first hit and then try to block the second, at certain ranges, the second hit will simply go through you. This occurs consistently when NM is close to Ivy. You must try and block the second hit for this to occur, if you simply stand there without holding G then you will still be hit. If you continue to 8WR then you will still be hit.
