So i was messing around trying to get it to work as if i wanted the bot to play i had to go into a game manually before it could begin to bot, i tried to rename my deck tons of times.
The solution i found was to if your playing a mage deck, you should call your deck "Mage" and use that deck in hearthranger. This worked for me, i got this idea as when i was on the screen where it said it could not find "Basic Mage" That there litterally werent any place to select basic mage anyways so i tried to rename it to the character i wanted it to play and it worked ^^
