@botwhat I found a pretty nasty and obvious bug, but I couldn't find the replay to use the debug tool. Not sure it's in the deck or the application.
Played the wild aggro druid, ran into a mill rogue. Mill rogue popped a secret. Without checking for the secret, the bot played savaged roar on a full board (lacks finesse, but I guess Hearthranger is meant as a blunt tool). Secret turns out to be evasion, which negates all incoming damage. Now here comes the bug: bot proceeded to continue trying to attack face even though opponent was immune. It kept trying for a good 30 seconds, until I intervened. Does this also happen when a mage plays ice block?
