If you want to have a try yourself please take some time to read the help file and examples thoroughly, kickstart some of your own edits and check what it does.
Editing itself is a pain even through a table editor, you keep jumping from Excel to MOBhack, and the only thing that will test is running endless random battles till the IA buy pick is right enough (IA purchases, you deploy).
Oh, and of course,

Edit: changed the DL address to a freshly uploaded file, probably some registration issue with the Yahoo site.
