Pioneer Izzet Unbreakable Formula Deck Brings Jace Beleren to the Combo

A Pioneer Izzet Unbreakable Formula combo list now has a full 60-card breakdown, and it makes room for Jace Beleren, Theorist from Reality Fracture. The deck is Izzet (blue-red) and is described as a combo deck.
The column gives the full main deck and the 15-card sideboard, then walks through the combo plan.
Pioneer Izzet Unbreakable Formula Combo Plan
Unbreakable Formula is a sorcery that destroys artifacts and creatures, then puts same-type cards from the library onto the battlefield. Its strength is that it can target X permanents.
The plan is to destroy your own creatures or artifacts, often tokens, so the sorcery puts creatures with mana value 7 or more onto the battlefield. Atraxa, Grand Unifier is the example named.
Tokens come from odd places. Mirex, Fountain Port and Consider all make artifact or creature tokens even though they are lands or an instant, and Great Hall of the Biblioplex can become a creature and be targeted.
Pioneer Izzet Main Deck List
The 26 lands:
- 4 Steam Vents
- 4 Stormcarved Coast
- 4 Spirebluff Canal
- 4 Sunken Citadel
- 2 Mirex
- 2 Fountain Port
- 3 Great Hall of the Biblioplex
- 1 Island
- 2 Mountain
The 3 creatures, one copy each, are Raph and Mikey, Troublemakers, Atraxa, Grand Unifier, and Vargavoth, Dread Devourer.
The 31 spells are listed below, with some cards kept under their Japanese names:
- 4 Consider (《推理》), 4 《かき消し》, 2 《否認》, 1 《三歩先》
- 4 《焦熱の衝動》, 3 《火山の悪意》, 2 《勝利の炎》, 1 《フラッシュバック》
- 4 Unbreakable Formula, 4 Fable of the Mirror-Breaker, 2 Jace Beleren, Theorist
Sideboard and Key Cards
The 15-card sideboard has 2 《神々の憤怒》, 1 《兄弟仲の終焉》, 2 《方程式の改変》, 1 《神秘の論争》, 1 《才能の試験》, 1 《三歩先》, 2 《星間航路の助言》, 1 《船砕きの怪物》, and 4 《サメ台風》.
Fable of the Mirror-Breaker supplies three targets: a 2/2 Goblin token that makes Treasure when attacking, and a chapter III flip into Kiki-Jiki, Mirror Breaker.
Vargavoth is a 9/9 flying lifelink demon with ward, and it can take cards headed to the opponent's graveyard. Attacking with Raph and Mikey lets Vargavoth or Atraxa enter attacking.
Jace Beleren, Theorist is a 4-mana blue planeswalker that makes Illusion tokens, draws on the opponent's draw step, and protects itself with walls and bounce. Its −6 draws three cards and boosts creatures, and it is also played in Standard.
TCGKing's take: the Fable package gives the deck three Formula targets from one card, so the real surprise is a four-mana planeswalker doing defensive work in a combo shell.
The author used Vargavoth to take an opponent's Jeskai Revelation while piloting the list.
