no bolt?

I would replace Clifftop Retreat with Battlefield Forge because you don't always need coloured mana but having a land enter tapped is really bad here. And after some tests in the simulator here I feel this may happen quite often, because 9 out of 20 lands are neither mountains nor plains...

With Kaladesh you can use Inspiring Vantage instead, even better!

Only 59 cards in the deck...

I would look into some card draw, since you are running low CMC cards such as Signal Pest, Springleaf Drum, Ornithopter, Memnite, and Mox Opal. That's twenty cards at CMC 1 or lower, plus twenty free lands...Maybe Expose Evil (clues are artifacts, so any investigate cards would work), Pirate's Pillage, Frantic Salvage, or Origin Spellbomb.Serum Tank would run well, as would Tamiyo's Journal or Trading Post.You could also run Nahiri, the Harbinger for a control/search element.
