The problem with Gonti's Aether Heart is that it comes down after you've already thrown most of your artifacts onto the field; it's a bit counter productive to enable.
I'm curious on how 3 Elder Deep-Fiend will test for you. Unless you stick a Glint-Nest Crane onto the field, you have no real sacrifice outlets except for Metalwork Colossus, which will typically mean EDF comes down when you're looking to finish the game, and you have four lands that can tutor for EDF when you need it. You could use something like Tezzeret's Touch to enable your Prophetic Prisms and Metalspinners to become viable sacrifice outlets for the fiend (which you could then replay on your next turn to draw a card), but that would require you to go Grixis.
I like the idea of adding Harnessed Lightning, as it gives a good usage for your Aether Hub energy, but let us know how it tests for you.
I'm really excited for Mirage Mirror; it gives a lot of utility in letting us copy an opponent's creature and crew Cultivated Caravan (without having to run more creatures in the main), copying an opponent's Glorybringer to swing and exert and potentially sacrifice for EDF, or to just copy an on-field Colossus and swing for game. Thoughts on this card?
Please don't talk about new cards outside of Standard New Card Discussion until the entire set is spoiled. Thanks! -- Lugger
Would you consider running Animation Module as a one of? Chains off with Olivia to create as many hasty 2/2s (or 3/3s) with Winding Constrictor as you have cards and mana. Could be clever to use as a finisher, or as an effective combat trick with Constrictor on the board.
The biggest issue I can think of with running a Pummeler deck at the moment is the introduction of Walking Ballista. As long as your opponent controls a Walking Ballista, you won't be able to push your Pummeler through unless you have some way to remove the ballista, or if you somehow have an absurd amount of energy. Any time you try to buff the Pummeler, they can respond by pinging him for one, which effectively nullifies your card. Considering the card is widely played right now to stop the Saheeli Rai + Felidar Guardian combo (and because it's just an amazing card in general), I think this would be an unfortunate time to try out Pummeler.
You might have more success with the Wandering Fumarole + Crackdown Construct combo(infinite Fumarole activations to make Crackdown Construct an infinite power/toughness creature.
