After reading a few topics here are there about how the AI sometimes renders your arena deck less powerful than you made it, I got to thinking, what if you had the ability to set when certain cards could be played? For example, sometimes the AI plays Luciferin when it has no creatures on the field, or when it has full health, or both. If there could be a way to set it up to where the AI for your arena deck would only play that specific card during certain situations? Just a thought. There would probably be a lot of programming that is obviously beyond me, but I think it's a good idea.
