Is scramble usable in pvp?

I used scramble to randomly scrambles the order of my opponent, but I still saw don pen at the end. Just wondering if it didn’t work

Perhaps Don used Retreat and went back to the end. 

I didn’t see that, maybe it just “happened” he was placed at the end again. Thanks for the answer. Someone just used that on me and did change my line up

It does work. I use if frequently, but Don can retreat, darn that penguin.  Or he maybe didn’t get shifted much.  I have also seen a player or two that did not start with him in the last spot.
