MAC era, soba, arena dupes…?

Since Mac discontinues all their good products… does anyone have dupes of their old Era, Soba and Arena eyeshadows? These used to be some of my favorite eyeshadows and then they disappeared…I found out too late. By the time I found out they were being discontinued they were pretty much gone/sold out And of course any dupes I’ve found are also gone/discontinued. Thank you for any assistance!
