Just a minor thing I notice about this bot is the lack of emotes to the other player. For example: if it can be calculated that the opponent will win next turn, have it say "Well Played", etc. I know this bot is in beta and there are many improvements to come, but humanizing the bot more will (possibly?) decrease detection of it. Always a fan of the buddy network, you guys/gals are doing great work here.
I think, as long as the bot doesn't try to play a card million times, when it is obviously not possible, play a powerful minion to destroy it 1 card later for some hp or something, we don't need any emotes as nobody knows, you are a bot. Nobody will write a report because he won against someone playing bad. If i play myself, i barely ever use emotes.
