There are 3 public bots that I know of, there are 2 other bots, but they are rumored to be behind closed doors, so I won't be covering those.
Disclaimer: I haven't used Buddy or Ranger since summer, so I am not sure how much they improved/died over the past 9 months.
Hearthbuddy: a giant shitshow of AI. Even rank 20 farming is shameful in terms of winrate. Customization didn't exist and writing plugins/mulligans was impossible (I think it still is unless you enjoy torturing yourself). Dead community.
Ranger: A better version Hearthbuddy with semi ok AI and lively community that used to care about progress. Last time I checked they werent doing much though.
Best for last (I am biased) SmartBot: Amazing AI perofrmance, and great arena AI since release of Whisper expansion. It already deployed 2 AI tweakes since whisper release. They have their own tracker plugin that shows you your performance against certain decks/classes and it easily knocks out legend with secret paladin in wild, even now.
Just for reference: This were my arena runs since the release of Whisper of the old Gods.
(100 gold usually converts to 2-3 packs steadily)
hey are you still using smartbot? last time I tried them was the dev expired everyone life time and increased the subscribe's price.
How is the community now and how is the winrate/ arena /rank goes right now?
