In some cases, ice z kyurem-b doesn't work out on the ladder, so I have thought up a really new, and hopefully meta changing set (not a shitpost lol)
Move Set

First of all, I know what you're thinking while reading this. "Is this guy insane???? outrage has more damage, as well as ice z being almost twice as much!" While this is true most of the time, YES this set does counter some things, and has its advantages. One thing it does is change the unfavorable match up against mega gyarados into I'd say about a 50/50, potentially even better. Second of all, it counters those pesky aegislashs if you can predict well enough. Ofc, it is generally unconventional to run this much speed on Kyu-b, it really helps against those slower mega-gyaras. Max attack is completely necessary, as it can shift the battle in your favor. Although you may also be thinking, "Is this man insane running normal freeze shock???? that move is so trash without zcrystal lol" Well actually, it works sort-of well against vensaur-mega, whimsicott, and many other grass types, as long as you can predict well enough. (doesnt really work well against ground types).
While this set has its advantages, it has its disadvantages too. Its one disadvantage is that it cant really deal too effectively with those sturdy-rock-z/ground-z users, like donphan, crustle, etc. Luckily, this set can be teamed with other mons who can cover those (honestly up to you), along with that fact that this will be generally unexpected (unless this actually catches on), so they normally wouldn't throw them out against you.
Alternative Moves
Replace Freeze Shock with Ice Beam - This could counter some of those sturdy users like donphan and perhaps do well against Venusaur-M more will have to be invested into spa if you would like, so you can adjust the evs to fit your liking.
Replace Freeze Shock with Iron Head - While this may remove the ice STAB bonus on certain attacks, it can cover certain things, like whimsicott, and other fairy types, such as TK and TL (also kentari is kinda making me put this in :P, would not recommend lol)
CONCLUSION
I think this set's greatest strength is in cteaming, especially in a tournament setting where you will most likely know your opponent's set, or on ladder, where you know who is on. This set is very situational, and I do not guarantee it works. It is solely meant for countering very specific bad match ups.
