Would Simian Spirit Guide help?

I run a similar deck Death by Kiln (2 Turn). You may use some Simian Spirit Guide for turn 1 Kiln and Slip Through Space for Serum Visions. Check out my deck and see if there are any ideas you get for either yours or mine! +1 from me for sharing this great deck with the world!

Tainted Strike I know another color yadda yadda. My friend built a deck with kiln fiend swiftspear and deaths shadow and there is so much Phyrexian mana instants that you can make deaths shadow big quick. Tainted strike makes unblocked kiln fiend super lethal. Maybe Crimson Wisps

I would recommend Slip Through Space instead of Distortion Strike, it may not give you the +1 damage but it replaces itself and that's a big deal in a combo deck like this.

Also Noxious Revival works really well with Mutagenic Growth and Gitaxian Probe, retrieve the growth with noxious then use probe to draw and cast growth again for mega value.

Probe's been banned in modern for a while now.

Should be worth noting that this deck hasn't been updated or commented on in over a year. :/

I just noticed that, kinda surprised he didn't check before deckcyling. Well, welcome back to the game.

Yeah I occasionally log in to see how the community is doing. It's habit to just deck cycle fast. Didn't think twice about it.
