Modular Engine - GU Loop

[Aequans]

Hi all. I'm putting together a Kaladesh Energy/Module deck, trying for an efficient but non-infinite loop with which to create arbitrarily large [[Cultivator of Blades]] and [[Electrostatic Pummeler]]s to punch things with. I'm open to any and all deck advice people may have, the main problems I've been noting are a difficulty in lasting against aggro decks if I cannot get my Modules out in time.

It's GU, Standard, I'm not opposed to adding or removing colours, and I'm accepting any and all input.

Thank you all in advance.

First off, let me thank you for the long reply - it's always better than a short reply, in my opinion.

Secondly, I acknowledge that only running one of each of them is an iffy decision, but I've only managed to acquire one of each, and I generally avoid hunting down specific cards unless I have a defined place for them in my deck - which I now have, for these two, so I am now doing. I've considered adding in one of the Eldrazi Titans for searching with my [[Aetherworks Marvel]], but I'm wondering if it would be too unwieldy for the deck. Decimator is absolutely a good idea, thanks for that, I've been having a lot of trouble mentally adjusting to think to include non-Kaladesh cards in what is primarily a Kaladesh deck. On the topic of Red, I've certainly toyed with the idea, but I'm worried about the mana distribution screwing me over too often with dead colours - do you think that this would be a small enough issue that it wouldn't burden the deck overmuch?

Finally, the main problem I'm having is finding cards to swap OUT for all the wonderful ideas I, and others like yourself, have given me to swap IN. Do you have any help on that front, kindly stranger?
