Confront the Unknown
: Early game this can help your creatures survive, while later in the game it can allow you to sneak in 13 more damage than your opponents might expect.
Thopter Spy Network: The clues you make are artifacts, meaning you will almost always have an enabaler for this.
Cranial Plating: the clues are artifacts, the thopters are artifacts, to not run this would be idiotic.
Invisible Stalker: A hexproof unblockable creature, triggers Ongoing Investigation, as well as being a perfect target for Cranial Plating
Tamiyo's Journal: the clues that this makes are ok, but, this is mostly in here for it's synergy with Briarbridge Patrol, this combo is the reason I run Ulamog, the Ceaseless Hunger
Dispatch: Path to Exile with no drawback? yes please.
Thraben Inspector: a cheap investigate trigger that can also be a chumpblocker.
Erdwal Illuminator: The amount of extra clues this guy makes is insane
Expose Evil
: The ability to investigate on an opponent's turn synergizes well with Erdwal Illuminator, but I might cut one or two of these for Dispatch, but I'm not sure yet.
