The owner of this deck hasn't added a sideboard, they probably should...

There's a toss-up between green and blue here. In a blue variant, I'd use on less Journal, and include Thing in the Ice; Trail of Evidence; Erdwal Illuminator; and a stack of counters, draw, bounce, tap and burn spells. I went with green ramp to actually afford to pay for the clue draw effect to dig out the Ghirapur Æther Grid / Pia and Kiran Nalaar, and to pay for Pia and Kiran Nalaar's ability.
Investigate, then use Ghirapur Æther Grid and Pia and Kiran Nalaar to turn the clues into burn / timing.
