Mana Severance to allow you to pull lands out of your deck to avoid dead draws.

Fabricate and Whir of Invention to help tutor specific pieces.

Arcbound Ravager, Emry, Lurker of the Loch, maybe Etherium Sculptor instead of or with Jhoira's Familiar

Maybe do a Grapeshot or Brain Freeze to have alternate storm wincons to Aetherflux

Maybe consider Cloud Key over your familiar just for the 1 cost reduction and the fact it isn't susceptible to creature removal.

Massacar Mana Severance is definitely on my radar, right now I'm just trying to power through the lands with a combination of a low land count and drawing more cards. I'll consider tutors, but I'm loathe to potentially spend an entire turn liking for 1 card. The ravager and emry are interesting. I am running etherium sculptor, and jhoira's familiar, and foundry inspector and herald of kozilek, semblance anvil and helm of awakening all to reduce casting costs, and pretty soon I'll be getting a Cloud Key to add to the mix. I actually use reservoir as a threat, you can see it, and if you do something to me in going to kill you at instant speed lol, but I'll think about some actual storm cards.

Thank you for the suggestions, I'll definitely use a few, I'm likely to use a few others, and I'll definitely consider the rest

RiotRunner789 indeed, in going to be adding cloud key to the mix for sure. It's my favorite cost reducing card, but it costs $20-30 so I wanted to get all my budget cards first. I would already have it if it weren't for having to pick up a Sensei's Divining Top (I had to pick one up lol, it's one of the best cards for this deck that isn't a $50+ mana rock)

Ancestral Statue its budget and it can target itself
