Need help muting the DMF trinket Shuffle Cards sound

[CrimsonAegis]

I finally figured out that a sound that's been driving me crazy is what wow plays when my DMF immortality trinket 'reshuffles' itself while in combat. Thanks to the wow forums, I now know that it is this particular sound Shuffle Cards - Sound - World of Warcraft, but that wowhead page does not seem to list the exact spell name or directory structure.

I did try using cascview64 to extract the sound directory to a folder and manually find the sound file but it appears the player made list file is an expansion out of date so Legion sounds don't get extracted or something.

Any ideas? Thanks in advance.

If this isn't the appropriate subforum, please let me know of a better one.
