I'm really exited to finally make this writeup. I've been having a blast playing this deck, and its felt like by far the strongest deck I've played in this standard format. Currently my record is 25-3 (89% w/l) across Bo3 games all played in top 300 mythic. If you want to ask more about the deck or see my future deckslists, I'm @ascoozeme on Twitter :)

The Core

Ever since Jim Davis absolutely smashed the Pro Tour with Fable of the Mirror-Breaker // Reflection of Kiki-Jiki, many players (me included) have been salivating over the card and jamming it in every color combination and shell imaginable. The card creates 2 creatures, both of which will run away with the game if left unchecked by the opponent. The Goblin Shaman token is a Ravagan, Nible Pilferer that doesn't have to connect and the backside is a scuffed Kiki Jiki, Mirror Breaker, which turns out to still be extremely good. The rummage effect from the second chapter isn't huge, but it adds a value and consistency to a card that was already powerful. To maximize Fable however, it's important to have targets for the backside to copy. 

Nobody who has gotten this far in the writeup is going to be suprised by the inclusion of Goldspan Dragon in this deck. It's a messed up card, acts as a 4/4 hastey flyer for 3 mana that ramps you. This deck has tons of ways to abuse the mana it gives you access too, and it closes out the game quickly. Bloodthirsty Adversary is one of the best ways to use Goldspan's mana as well as a powerful target to copy with the backside of Fable. I've been incredibly impressed by the card, and would never consider cutting it. Wandering Mind is the best target for Fable: 6 cards deep is a LOT of selection, and it has incredible hits in the deck, including Fable of the Mirror-Breaker // Reflection of Kiki-Jiki itself.

The rest of the deck is interaction, lands, and everybodies favorite Izzet Cantrip:



Not only do you get to play the best card in Standard, you can consistently find it with Wandering Mind and recast it with Bloodthirsty Adversary. This card should really be banned but for some reason it isn't, so we are playing it.

Interaction

Discounting 2 Jwari Disruption 2 Shatterskull Smashing and 1 Spikefield Hazard which I'm including as part of the mana base, the deck runs 15 pieces of interaction.

4 Voltage Surge: Mostly a shock, but thats suprisingly good in this meta. Lots of planeswalkers and Fables floating around.
2 Fading Hope: Fading Hope is back to being good again. Tokens are everywhere, and Runes is a deck.
3 Dragon's Fire: Nothing exciting here, just a 2 mana removal spell. Best option in Izzet.
3 Negate: Yep, 3 maindeck negate. Find a deck that doesn't run a good negate target, I'll wait. Also Goldspan.
3 Prismari Command: Shock being good in the meta also makes prismari command good, hitting artifacts is crucial against Oni-Cult Anvil, Reckoner Bankbuster, and Esika's Chariot, and the other 2 modes are below-rate but add a lot of consistency. 

Manabase

27 lands is a bit less then usual for Izzet decks, which tend to play 28-30 including spell-lands. Without Magma Opus or the now-banned Alrund's Epiphany though, this deck rarely needs more then 5 lands. Plus, Expressive Iteration, Fable of the Mirror Breaker, and Prismari Command can help you hit lands in a pinch. The manabase is otherwise pretty typical 2 Jwari Disruption 2 Shatterskull Smashing and 1 Spikefield Hazard fill the spell-land role, 2 Den of the Bugbear and 2 Hall of Storm Giants give you some creature-lands, and the rest is the legendary lands and basics.
