Here's a simple Critical Edges punishment guide I made for Ivy. I tried to bring every possible situation to punish CEs (regular block, Just Guard and whiff punishing) from different distances. Hope it'll be useful!
00:01 Aeon (the second and third punish only can be done from zero range).
0:30 Alpha Patroklos
0:44 Astaroth (his CE is zero frame grab, you gotta guess and duck before its animation).
0:52 Cervantes (safe from distance).
1:01 Elysium (8B+K can be done from this range too, but sometimes whiffs).
1:13 Ezio (can be SSed only from zero range).
1:35 Hilde (can be SSed only from short range).
2:01 Ivy (her CE is zero frame grab, you gotta guess and duck before its animation).
2:09Leixia.
2:25 Maxi (you don't need to JG the first hit to JG the 2nd and 3rd).
2:47 Mitsurugi.
3:01 Natsu.
3:31 Nightmare.
3:39 Omega.
3:58 Patroklos.
4:24 Pyrrha.
4:48 Raphael.
5:04 Siegfried.
5:12 Tira.
5:40 Viola (This punish only works from this distance).
5:48 Voldo (2A is the only move that interrupt all of his follow ups. Even with JG).
5:56 Xiba.
6:11 Yoshimitsu
6:30 Z.W.E.I
EDIT: Algol's punish
