Below you will find a link to an old post. This will take you to a list of hero builds which work well with the default ai ruleset which comes with HearthRanger.
Basic DecksThe ruleset located on that post is also pretty useful, so you may want to download that too.
I ran the basic mage deck last night for 6 hours and received 26 wins (48% win percentage).
To use a ruleset:
Open the program (give it about 30 seconds to connect with the server) and click on the "Edit Task" button.
Find the tab "Step 1: Basic Settings".
There should be three drop boxes. Select the Game Type (I suggest Unranked this early in the month or during prime time hours); the deck you created; and finally "DeckRules_Control.xlsx"
If you do not download the control ruleset, you should see an option to select "DeckRules_Default.xlsx"
Below are a couple of options to be aware of if you are just starting out.Under the tab Auto Concede Option, I check off Auto concede if HP< 5 and opponent is > 25. You can set the minimum higher so the program does not fight losing battles and just moves on to the next match.
Under the tab Auto Daily Quest, I check off my daily quest (or quests if I have been lazy). Each line should have two drop off boxes. Select the deck you want to use and the ruleset (default or control is fine). Go back to the basics tab and select your gameplay (ranked or unranked) and "As Daily Quest Deck" from the deck selection drop down box.
Under the tab Auto Stop Option, I select "Stop bot when no more gold rewards and daily quests." This will run the bot till it has completed any selected daily quests and attained the 30 wins necessary to gain the maximum 100 gold for the day.
