Just for fun I see that, but how are you searching up enough mana sources to cast Crush of Worms? Or are you relying on Dawnglow Infusion to help you survive? May need some form of board sweeper like Wrath of God or something to wipe out ALL nonartifact creatures vs aggressive deck. Consider Boseiju, Who Shelters All to force through Crush.

Speed it up by eliminating Blast of Genius and Staff of Nin. Tibor and Lumia will take out your own Goblin Electromancers too quickly too. Using Guttersnipe will turn every instant/sorcery into 2 damage as well. Things like Remand (counter target spell, draw a card) start getting nasty with a pair of Guttersnipe out there. I'd likely cut Empty the Warrens for an additional Izzet Boilerworks.
Might also do +2 mountains somewhere (or Blood Crypts if you have them) to help smooth out the mana. Doing sample hands showed mana was a bit too thin, often getting stuck at 3 lands, and that not coming until the 4th drawn card.
I would ditch the caterwauling boggart. It looks like your plan is to pump with Auntie/King/Chieftain and be able to pound through with Krenko. I'd also ditch the Lackey as almost everything you have is super cheap. Try to focus the deck a bit more for consistency. I'd add another shenanigans, mentor, mob, witch and then try to self test it OR at least goldfish the deck a few times to see what cards you want to draw and what cards you go "dang! not that thing!" when you draw.
