This deck is all about trying to get an early Possessed Portal into play and using it to eliminate your opponents hand and board presence with it. How? We rely on various outlets such as Thrilling Discovery and Goblin Engineer to put Possessed Portal into the graveyard where we can reanimate it with either Trash for Treasure or Refurbish. Once we have a portal in play we have Squee, Goblin Nabob and Squee, the Immortal to use as extra cards to break portal symmetry. You can even use Magda, Brazen Outlaw in combination with Springleaf Drum to make treasure tokens to sacrifice. Magda also allows Universal Automaton to help make treasures as well.
Sideboard: I've tried to make this something of a transformative sb for surprise value.
Irencrag Feat: Mana acceleration for when we have to pay full price for portal or Karn from the sideboard.
Karn Liberated: The role I have in mind for Karn is to be a major shift in the way I'm attacking an opponent's game plan. It's ability to attack hands or remove troubling permanents from the board is a big help.
Lightning Bolt: Flexible removal/win condition. I'm sure you can think of a way for it to help.
Magus of the Moon: Non-basic land hate for greedy mana bases or decks trying to leverage Urza's Saga.
Nahiri's Wrath is an additional discard outlet for decks that go too large for fury.
Jaya Ballard, Task Mage is to hate on things like Murktide Regent, teferi's, or even Omnath, Locus of Creation. It also functions as a discard outlet and win condition with Squee, Goblin Nabob. Enabling Mox Amber to tap for mana also helps. (Considering if this is main deck worthy).
Notes: One of the big issues I'm looking to overcome with this deck is initial mana troubles. I have thought about adding more lands, but it will come at that cost of either cards to pitch to Fury or weakens the synergy between other pieces.
