I do have a question however: When describing how opposing wonders work, you say "The non-wonder card the opposing Patron laid down acts as the new DC for the skill check. This can happen multiple times per skill check." Why would it happen multiple times? The new DC either fails the skill (so no new wonder is needed) or it does not (so why even do it?)
As mentioned on another comment, this was five years ago, so pardon my forgetfulness, but I think I initially wrote this intending for there to be multiple wonders played. I.e. Controlling patron plays a wonder, opponent counters it, controlling patron plays *another wonder*, another opponent counters it, so on and so forth - all over a single skill check.
