Vicious ES?

Has anyone actually obtained one of these recently? After hundreds of intermediate and advanced runs of Their Method I've got Giant, Burgundy Bear, Breeze, and Water Drop but no Vicious. I've got four Shock pg 9 and a handful of elite passes and red upgrade stones too.

Is it just ridiculously, stupidly rare or is there some incorrectness in the data?

Ridiculously rare, I've gotten one or two from Intermediate runs, a lot of runs.
