There is only really one cycle reminiscent of the Scars of Mirrodin Spellbombs. Nihil Spellbomb, the black one, was the better Spellbomb in Scars of Mirrodin. The black one here, Metalspinner's Puzzleknot also looks to me like the strongest one.
There is also a three-some. The three modules share a name, and Decoction Module and Fabrication Module are part of the Energy economy, with one getting you Enters the Battlefield (ETB) Energy and the other one letting you exchange Energy for +1/+1 counters. Animation Module might as well be a separate card, except that it can give you one more Energy counter, or any other counter (this is really powerful, in my opinion, when we look back at all those counters we would like to have more of in Modern, Legacy, and Vintage). Oh, and Animation Module can be used as a token maker if you are willing to pay the one mana stall per token.
