There may be similar decks out there, but I built this deck entirely on my own after my Power Conduits caught my eye during perusal of my collection. It was hard to narrow the deck down to 60 cards because there are just so many cards that work well with the theme and mechanics. This is evident when you look at the scratch pad.
 
This Legacy deck is all about generating charge and +1/+1 counters and pushing them all over the place. You can play the Everflowing Chalices and Astral Cornucopias for 0 mana and load them up with charge counters via your Surge Nodes, Energy Chambers, Contagion Clasps, Power Conduits, and Coretappers to rapidly ramp your mana. The mana ramp via the artifacts is so significant that you can effectively play an entire game with only 2 lands on the board (hence my decision to only include 20 lands in the deck.)

With your surplus of mana, you can start putting all of your modular creatures out and pumping them up with the Power Conduits, Contagion Clasps, and Energy Chambers. Unwinding Clock will allow you to pump via the Power Conduit and other tap-able artifacts during your opponents' turns. You'll have mana during their turns too because all of your lands are artifact lands* and will untap as well. And then you can hit the Lux Cannon to clear your path to victory.

This is such a fun deck to play. There are so many possibilities built into it that it is a busy deck to play. Your will have so much to do during your turn and a lot of bookkeeping. This is definitely not a deck you want to play after you've had a few beers.

And remember, Arcbound Fiend can pull counters off of your opponents creatures too!

* I know that artifact lands have been banned in many formats due to their tendency to make affinity over-powered. However, because I have no affinity in this deck, I don't feel badly about using them.

Notes:

The mana ramp is so effective that it empties your hand quickly. And, due to the proportionally fewer number of creatures in the deck, being on the draw can be agonizing if not fatal.I want to work Loreseeker's Stone into this deck in order to facilitate aggressive drawing after the hand is exhausted. Everflowing Chalice, Coretapper, and Surge Node are candidates for replacement (priority in the order listed.) Brain in a Jar could also help.
