I'll keep it simple.
The Staff of Perplex for Rubick looks a bit odd. If you look in your steam inventory at the Staff of Perplex, you will see that it has the image of a force staff.
But if you search for it at the steam market, you will see that the golden version of this staff has the image of... what it should look like.

Gyazo to see what I mean:
