What does not
You need to install .net and corefonts
You need to run the following Wine tricks for MTGO to install and work:
winetricks corefonts dotnet45 ddr=gdi win7
What was not tested
Limited of any sort.
I listed wine 2.21 because it is the oldest I could select. I actually tested on wine 2.20 because wine 2.21 has a regression of some sort that does not let MTGO start up.

Use at least Wine version 3.7.
Staging is required for multimonitor systems, otherwise game will fail to start. (Alternatively you can just apply only multimonitor staging patchset)
You will need following prerequisites in your magic prefix (32bit prefix):
winetricks -q corefonts dotnet46 win7
On OSX I had to do
otherwise MTGO window was not properly (re)drawn
For sound to work you need wine built with gstreamer. Gstreamer has to be able to play wav files.
If for whatever reason you would like MTGO to not even be able to try and reproduce sounds - you can set "wmp" to "disable" in DLL overrides in winecfg.
