I have no major complaints. Random hover would be really nice, I agree. No requirement for emotes one way or the other.
I would however like some simple stuff though regarding card usage. Ie: With cards that have some requirements, maybe have the ability to set it so you can always meet that criteria. Ie: Certain combo cards are only used in combos (if you set it for those card(s)). Druid cards of choice only do one option, and the bot never considers the other (aka, Ancient of War 5/10 Taunt generally more useful than 10/5). Quarter Master never plays without at least X Silver Hand recruits. Place a trap if you have the spare mana instead of ending turn and keeping the trap in hand (honestly, this one is really stupid). If this kind of stuff would be allowed to be edited on our side, that's all I would ask.
