Wow! I never been thought such a synergy with clues! Really nice deck!

Also what about adding one Ulamog, the Ceaseless Hunger (or any huge creature ) to tap Tamiyo's Journal at the end of their turn , search for Ulamog, put it in play with Briarbridge Patrol and attack at your turn with Ulamog!

I like this build, but I can't get past the question: What is the win condition? Card advantage to draw into what? Just a bunch of weenies to attack with? Maybe I am missing something...?

Sorry...for previous post. I don't see a way to edit it. Going to give this try tonight.

Solid deck. Upvoted. I've been messing around with a clue deck as well, in case you're interested: Inspector Gimmick's Clue Deck.

Since you've got 4 copies of Ulvenwald Mysteries in there, see if you can get your hands on a copy of Westvale Abbey  ^Flip. Never hurts to get another win condition in there. In addition to your other counterspell cards, I'd recommend considering Essence Flux as removal for your biggies is going to be your opponent's number one priority.

I would also consider adjusting the mana base slightly, as you're pretty heavy on white creatures, but all your white mana sources come out tapped. That may make a difference against aggro decks. And since Evolving Wilds is still standard legal, you'll want to get four of them in the deck. You can net four clues between your turn and your opponent's turn on one Evolving Wilds, one Tireless Tracker in play, and one Erdwal Illuminator in play. Makes Confront the Unknown that much more of a beast when you swing in on the following turn -- netting you two more clues off of Erdwal Illuminator

If you get a chance, leave an update on how the deck is performing. I'd love to hear how it goes.

Thank you all for leaving comments and upvoting it! I have made a few changes to the deck based on your suggestions. I've added Ulamog, the Ceaseless Hunger as a finisher, main boarded Thraben Inspector, and fixed the manabase. Please continue to leave suggestions and thank you for all of the support!
