Not every Commander upgrade needs to cost $30 per card. MTG Marvel Super Heroes releases June 26, 2026, and all four Commander precon decks are strong enough out of the box to play immediately — but targeted budget additions can dramatically increase their consistency and power without breaking the bank. This guide identifies the best Commander upgrades available for under $30 total per deck.

Avengers Assemble — Best Budget Upgrades Under $30
Captain America, Team Leader is already a strong commander out of the box. The precon’s main weaknesses are mana base inconsistency and a handful of low-impact creatures occupying slots that better Hero synergy pieces would fill. These five additions fix both problems for a combined cost under $30.
Maskwood Nexus — $3–5
The single most impactful budget upgrade for Avengers Assemble. Maskwood Nexus makes all creatures every creature type simultaneously. Since the deck runs Herald’s Horn, Door of Destinies, and Kindred Discovery, turning every creature on your board into a Hero for those cards is a significant power increase. One card amplifies every tribal synergy you already have, including the Path of Ancestry scry and Unclaimed Territory fixing.
Urza’s Incubator — $6–10
Reduces the cost of a chosen creature type by two. Name Hero and every single creature in the deck costs two less. This reshapes the entire mana curve — creatures you were casting on turns 4–5 are now arriving on turns 2–3. In a deck that wants to flood the board quickly to maximize Teamwork triggers, this acceleration is immediately felt.
Jetmir’s Garden — $2–4
A Triome that enters untapped under normal conditions and fixes all three of the deck’s colors simultaneously. Direct upgrade over Coastal Peak. Taps for white, blue, or red, and the basic land types it has enable additional synergies with other lands in the deck.
Generous Gift — $3–4
Three-mana instant that destroys any permanent — creature, artifact, enchantment, planeswalker, or land — and gives the opponent a 3/3 Elephant. No restrictions. No conditions. The best catch-all white removal spell in Commander and a direct upgrade over any removal spell costing four or more in the precon.
Swiftfoot Boots — $2–3
Gives a creature hexproof and haste for two mana equip. Protects Captain America or any key Avenger from targeted removal immediately after they enter. The haste means attackers coming down as blockers are suddenly threats. Cheap, efficient, and directly solves the “your commander gets removed before it does anything” problem.
Total estimated cost: $16–26
Doom Prevails — Best Budget Upgrades Under $30
Doctor Doom’s deck already wants to run a long game and drain opponents passively. These budget additions amplify the drain engine and fill the gap the precon leaves in graveyard interaction.
Underworld Dreams — $2–3
A passive enchantment that deals one damage to each opponent whenever they draw a card. Four players drawing multiple cards per turn cycle makes this deal 20 or more damage across a game with no additional investment. One of the best passive drain effects in Commander at two mana.
Morbid Opportunist — $2–3
Draws a card the first time a creature dies each turn cycle. In a Villain-heavy deck with combat damage, sacrifice effects, and connive, creatures die frequently on all sides of the table. This card draws you cards at a rate that consistently outpaces its single mana cost to cast.
Dreadbore — $2–3
Two-mana sorcery that destroys any creature or planeswalker. No restrictions, no conditions, no exile clause to worry about. Among the most efficient removal spells in Grixis and a direct upgrade over any three-or-four-mana removal in the precon’s spell suite.
Baleful Strix — $3–5
A 1/1 flying deathtouch artifact creature that draws a card when it enters. It is an artifact creature (maintaining Doom’s indestructibility condition), draws a card (fueling the connive engine), blocks anything flying (defensive utility), and costs two mana. Exceptional value that works on every axis the deck cares about simultaneously.
Viscera Seer — $2–3
Free sacrifice outlet that scrys whenever you sacrifice a creature to it. In a deck that wants creatures dying for connive triggers and death payoffs, having a free sacrifice outlet gives you control over your own death triggers and enables instant-speed responses to exile effects.
Total estimated cost: $11–17
Wakanda Forever — Best Budget Upgrades Under $30
T’Challa’s Vibranium engine benefits most from counter amplification and draw attached to token generation. These additions maximize the value of every Vibranium token and smooth out the deck’s card flow.
Hardened Scales — $5–8
Places one additional +1/+1 counter whenever counters are placed on a creature you control. Every counter placed becomes two. If T’Challa generates counters on entry or through his abilities, this doubles the output for one mana. Compact, powerful, and directly aligned with the deck’s primary mechanical axis.
Skullclamp — $5–8
Equips to a 1/1 for one mana; if the equipped creature dies, draw two cards. Vibranium tokens are likely 1/1 artifact tokens. Every Vibranium token equipped with Skullclamp becomes two cards in hand on the way out. Converts token generation directly into card advantage.
Rishkar, Peema Renegade — $1–2
Enters with +1/+1 counters on two target creatures and makes each creature with a counter tap for one green mana. In a counter-heavy deck this adds substantial mana from your creature base, reducing how many lands you need to hold up for key plays.
Inscription of Abundance — $1–2
A flexible green instant with three modes: put two +1/+1 counters on a creature, have a creature fight another, or gain life equal to a creature’s power. At three mana with two modes available it is efficient utility that interacts with every phase of the game. The counter mode advances T’Challa’s strategy directly.
Heroic Intervention — $6–8
Gives all your permanents indestructible and hexproof until end of turn for two mana at instant speed. The definitive response to board wipes and mass targeted removal in green. Essential for protecting a developed Vibranium engine from the sweepers every Commander pod eventually has.
Total estimated cost: $18–28
The Fantastic Four — Best Budget Upgrades Under $30
The Fantastic Four benefits most from draw engines that fire off noncreature spells and universal copy effects that work under any of the four commanders. These additions are chosen for their impact across all four commander builds.
Archmage Emeritus — $4–6
Draws a card whenever you cast or copy an instant or sorcery. In a noncreature spell-heavy deck this draws multiple cards per turn consistently. Works under all four commanders and is one of the highest-value common commander upgrades available at this price point.
Guttersnipe — $2–3
Deals two damage to each opponent whenever you cast an instant or sorcery. Free damage every time you cast a spell. Under Human Torch this is additional burn damage. Under Mister Fantastic it fires on every spell in a copied trigger chain. Cheap and effective.
Strionic Resonator — $3–5
Copies any triggered ability for two mana. In the Mister Fantastic build this creates a second independent copy engine. In the Invisible Woman build it copies protection triggers. Under any commander it generates extra value from the most impactful triggered abilities in the deck.
Raugrin Triome — $8–12
A three-color land that taps for white, blue, or red and can be cycled when you do not need it. Essential mana fixing for a four-color deck and a direct replacement for the weakest ETB-tapped land in the base. Takes the most critical step toward solving the deck’s mana base with one card.
Young Pyromancer — $2–3
Creates a 1/1 Elemental token whenever you cast an instant or sorcery. Generates a persistent token army from spellcasting, giving the deck board presence that compounds over a long game. Works under Human Torch for aggro and under Mister Fantastic for the combo build.
Total estimated cost: $19–29
Universal Upgrades Worth Considering for Any Deck
Command Tower — Already in all four precons. Mentioned for completeness.
Arcane Signet — Already in all four precons. The best two-mana colored mana rock.
Swords to Plowshares ($3–5) — Already in Avengers Assemble. Worth adding to any other precon that runs white and lacks the best one-mana white removal spell in Commander.
Generous Gift ($3–4) — Three-mana instant destroy anything. Universally useful in any white Commander deck and absent from most precons.
Sol Ring — Already in all four precons. The best two-mana mana rock in the format, present in the box.
Final Word on Budget Upgrades
The best budget upgrades are the ones that fix a specific weakness in the deck you are playing rather than generic “good Commander cards” that happen to be inexpensive. Each recommendation above addresses a known gap in the relevant precon — mana inconsistency, draw engine weakness, removal gap, or counter amplification. Start with the upgrades targeting your deck’s most frequent failure point and work outward from there.
All four MTG Marvel Super Heroes Commander precons release June 26, 2026, at $74.99 standard. Add the budget upgrades above and you have a significantly stronger deck for under $30 more.
