Precon Upgrade Guides

Pick a Commander precon and get up to 15 prioritized one-for-one upgrades at $10, $25, or $50 — or any custom budget. Plans are built from the real out-of-the-box decklist with live prices, stay Commander-legal by deterministic rules, and export as a ready-to-order decklist.

FRC · 2026

Multiverse Reforged

Commander: Jace, Multiverse Architect

BRUWFour-color Polymorph

Use Jace to turn small tokens into high-impact creatures and planeswalkers. Prioritize repeatable token creation, top-deck control, and protection for Jace.

FDC · 2026

Calling All Angels

Commander: Giada, Font of Hope

WAngel Tribal

Giada accelerates Angels and makes each later Angel larger. Add efficient Angels and card draw so the deck can keep deploying threats.

FDC · 2026

Keen Engineering

Commander: Sai, Master Thopterist

UArtifact Tokens

Sai rewards each artifact spell with a Thopter. Cheap artifacts and artifact recursion turn those tokens into sustained pressure and card draw.

FDC · 2026

Wretched Ranks

Commander: Ghoulcaller Gisa

BZombie Tokens

Gisa turns a creature’s power into a Zombie army. Reusable sacrifice fodder and death payoffs make every activation matter.

FDC · 2026

Reign of Dragons

Commander: Lathliss, Dragon Queen

RDragon Tribal

Lathliss doubles down on nontoken Dragon entries. Cost reduction and haste let the deck produce Dragons before opponents can answer them.

FDC · 2026

Tramplesaurus Rex

Commander: Ghalta, Primal Hunger

GBig Creature Stompy

Ghalta rewards early power on the battlefield. Efficient creatures, draw tied to creature power, and trample support keep pressure high.

MSC · 2026

Avengers Assemble

Commander: Captain America, Team Leader

RUWHero Counters

Captain America gives entering Heroes haste and counters. Favor low-cost Heroes and ways to multiply or protect those counters.

MSC · 2026

Doom Prevails

Commander: Doctor Doom, King of Latveria

BRUVillain Connive

Doctor Doom connives with a Villain each combat and drains opponents when lands are discarded. Add repeatable discard and graveyard value.

MSC · 2026

The Fantastic Four

Commander: Invisible Woman

GRUWNoncreature Spells and Tokens

Invisible Woman makes Walls after noncreature spells, then turns a wide board into an unblockable attack. Cheap interaction and token makers support both halves.

MSC · 2026

Wakanda Forever

Commander: T'Challa, the Black Panther

GWArtifact Ramp

T’Challa creates Vibranium and grows when large artifacts are cast. Keep enough artifact spells to spend that restricted mana efficiently.

SOC · 2026

Lorehold Spirit

Commander: Quintorius, History Chaser

RWGraveyard Spirits

Quintorius makes Spirits when cards leave your graveyard. Repeatable recursion and low-cost graveyard interaction build a board for the double-strike finish.

SOC · 2026

Prismari Artistry

Commander: Rootha, Mastering the Moment

RUBig Spells

Rootha turns an instant or sorcery cast before combat into a hasty Elemental. Cost reduction and flexible spells make that trigger more reliable.

SOC · 2026

Quandrix Unlimited

Commander: Zimone, Infinite Analyst

GUX Spells and Counters

Zimone discounts the first X spell each turn as her counters grow. Instant-speed X spells can trigger the discount on opponents’ turns.

SOC · 2026

Silverquill Influence

Commander: Killian, Decisive Mentor

BWAuras and Goad

Killian goads creatures when enchantments enter and draws when enchanted creatures attack. Cheap Auras and protection keep the engine running.

SOC · 2026

Witherbloom Pestilence

Commander: Dina, Essence Brewer

BGSacrifice and Lifegain

Dina draws once each turn when a creature is sacrificed. Repeatable fodder and sacrifice outlets can collect cards across every turn cycle.

TMC · 2026

Turtle Power!

Commander: Heroes in a Half Shell

BGRUWMutant Ninja Turtle Combat

Heroes in a Half Shell rewards combat damage from Mutants, Ninjas, and Turtles. Evasion and protection help several creatures connect.

ECC · 2026

Dance of the Elements

Commander: Ashling, the Limitless

BGRUWElemental Evoke

Ashling gives Elementals evoke and copies them when sacrificed. Prioritize powerful enters-the-battlefield effects and ways to keep or reuse the copies.

ECC · 2026

Blight Curse

Commander: Auntie Ool, Cursewretch

BGRMinus-One Counters

Auntie Ool rewards placing -1/-1 counters on any creature. Repeatable counter sources and counter synergies sustain cards and life loss.

C17 · 2017

Vampiric Bloodlust

Commander: Edgar Markov

BRWVampire Aggro

Edgar Markov builds an unstoppable Vampire horde: every Vampire cast creates another attacker, and Eminence grows the whole board without casting a thing. Upgrades cut slow high-cost cards for cheap Vampire payoffs, fast mana, and protection.

KHC · 2021

Elven Empire

Commander: Lathril, Blade of the Elves

BGElf Tribal Swarm

Lathril drains the table by tapping ten Elves. The deck swarms cheap Elves, generates overwhelming mana, and converts the horde into damage. Upgrades add untap engines, Elf lords, and reliable card draw.

40K · 2022

Necron Dynasties

Commander: Szarekh, the Silent King

BArtifact Reanimator

Szarekh mills artifacts into the graveyard and reanimates them for free. The deck grinds value from artifact synergies and recursion. Upgrades add efficient self-mill, cheap reanimation, and artifact payoffs.

AFC · 2021

Draconic Rage

Commander: Vrondiss, Rage of Ancients

GRDragon Aggro

Vrondiss makes Dragon tokens whenever damaged and rolls dice to burn the table. The deck plays aggressive Dragons and damage-based payoffs. Upgrades add haste enablers, extra combat, and Dragon cost-reducers.

How upgrade plans work

  • Real decklists. Every plan starts from the actual precon contents (sourced from MTGJSON deck data, recorded on each guide) — never a guess at what is in the box.
  • Honest budgets. The upgrade cost is the sum of added-card prices at current data — you already own the precon, so you only pay for what goes in. Cards with no available price are left untouched and labeled.
  • Legal by construction. Swaps are one-for-one (lands for lands, spells for spells), additions respect color identity, and every upgraded 100 is re-validated by deterministic Commander rules.
