As the topic mentioned I assume u use silverfish as AI?
You can set up your own settings this way:
1. Go to your HearthRanger folder -> ExternBots -> silverfish
2. Creat the following text files within this ordner:
_mulligan
_settings
_combos
3. You have to write your own things in it to get it clear.
Here you can find a guide for mulligan and
here is one for the combos.
If you are a rookie with HearthRanger, I would recommend, that you go to
this and take a deck from there with mulligan, combo and settings included. It's easier to understand if you see a correct code.
Of corse I would recommend my Pala Midrange Deck, but since it has a very high mana costs to craft, try something else out.
