this deck is a former standard brew for Electrostatic Pummeler with new toys available in pioneer. this is built off the module cards form kaladesh: Decoction Module, which gives you 1 energy every time a creature enters the battlefeild, Fabrication Module, which gives you a +1/+1 counter on target creature when you gain energy, and Animation Module, which lets you pay 1 mana for a servo, but only when you put a +1/+1 on something. each of these cards has a secondary activated ability which triggers the step before them in the loop. so from that point forward, as long as you have a creature to etb, you can trade any amount of remaining mana for 2/2 servos.
around this shell, I chose a mono blue tempo gameplan. Glint-Nest Crane gives us the ability to dig for artifacts, and a 1/3 body.
the two stars of the deck are Electrostatic Pummeler and Unctus, Grand Metatect, with pummeler going "tall" and Unctus going wide. Pummeler gain energy on ETB, so with all 3 modules on board, it immediately gets 2 +1/+1s. pummeler can double power for energy, making Slip Through Space a wincon if hes on board, or a very fast dig if he isnt and anything IS on board. Unctus has looting and an artifact lord effect when our board is made.
Renowned Weaponsmith is a mana dork for artifacts, and we are certainly playing artifacts. one or more of him in hand can accelerate your game plan quicly, but more than like 2 and youre likely to run out of things to meaningfully spend mana on and fall apart. Inspired Idea is a draw spell, since we arent holding cards in hand. 0 max at end step is not a negative, and the 4 max in hand isnt actually too bad.
Whir of Invention is a veritable "I win" button for sequencing. If you need a piece, it can get it for you (you might just need another island or animation module first)
I am still figuring out what to sideboard into this deck, especially given how slot intensive the main cards are. Im excited to try it out though!
