[Custom Deck] Silverfish AI

I think I missed something, how exactly does this work?
Do I need to create a custom deck on hearthstone itself?

 

Is this better than the default bot?

 

If someone understand how to use it, can tell me plz?

 

some updates:
-fixed crash with youthful brewmaster and mimironshead
-silverfish can now read settings from an settings.txt file can be found here: https://github.com/noHero123/silverfish/blob/master/settings.txt
-somewhere on my github-page you might find a silverfish.exe.config file which speeds up silver.exe (for developers: gcServer is used instead of the default one)
-some other fixes/tweaks
