This obviously was before Tinkmaster Overspark were nerfed, so just switch him with another Ancient of Lore and you should be good to go.
Some tweaks could be done like switching Twilight Drake with Yeti, removing one Starfall, maybe put in two Wild Growth instead of Claw, but that's all up to you and your playstyle of course.
It's closer to a Ramp deck than a Midrange deck in my eyes.
