Blade of Artifice 2.0.
I've been messing with additions and subtractions for the past two weeks, but with the current meta I feel this setup is the best one to sit on.
I've been playing with it and goldfishing up some great scenarios - a LOT of the cards synergize with each other, and it's hard to find a playthrough where things don't just "click".
The biggest addition to the deck so far is Metallic Mimic (calling Artificer). It triggers the Inventor's Goggles and turns a 2/1 into a 3/3 on turn 2, allowing any future Artificers to be pumped the later the game goes.
Worth noting that it turns Mimic into a Heart of Kiran crewer. There's a minor energy subtheme, with Aether Hubs and Harnessed Lightning. It's not uncommon to have a stockpile setup where you can blast a high priority target out of the water, or continue generating value hits with Aethersphere Harvester for lifegain.
Thalia used to be in the main, but Pia has really outshined her by giving you an artifact when she enters, being an Artificer, and her abilities are relevant (making unblockables, etc).
A big surprise hit to me has been Skeleton Key - it becomes Inventor's Goggles 5 and 6, but the ability on Heart of Kiran or Aethersphere Harvester (or Pia's token!) makes Smuggler's Copter re-appear much to the bemoans of the opponent.
I'm really excited to try out this deck when I get the pieces together (I still need two more Pia Nalaar) and see how great it is in paper practice.
