I only learned COIN myself within the last year. Not sure it will help you or not, and maybe obvious, but I found the best way was just follow what the rules say literally and not look for rules that are not there, make assumptions, etc. The more literal ("one word" can make all the difference for a rule) I followed the rules, the better it went. The BOT's are worse for interpretation especially if you think too much about what the rules say. But they are a bigger headache to tackle....
Boy, isn't that the truth? I have played a couple of games of LoD (so, still a n00b) and am trying to wrap my head around the bots. I am having little luck thus far.
