I've been playing a few games with mainly the core set decks, though enough thrown in to make mono decks possible. So far the core set Agency/Miskatonic combo seems quite poweful, mainly because of agency's sheer power (though also for investigation).
What would be basic strategies to counter the Agency (specifically in terms of the core set + a single copy of each of Summons of the deep)? Presumably something like insanity and combat (e.g. Hastur/Cthulhu). Would there be any other good, possibly non-icon based strategies? I'm playing quite casually, and am just looking for general hints. Apart form anythign else I quite like the idea of mono decks, and am keen to develop them a bit.
