Marvel Super Heroes MTG: Best Cards & Proxy Guide
Marvel Super Heroes released on June 26, 2026, and it is one of Magic's biggest superhero crossovers to date — a full-size Standard-legal set built around the Avengers, the Fantastic Four, and a villain roster headlined by Thanos, Doctor Doom, and Ultron. It immediately produced major secondary-market attention, especially around premium Collector Booster treatments and Infinity Stone cards.
This guide walks through the main set's standouts — what each one does, its current secondary-market context, and where to find a high-quality proxy if you would rather spend that money on the rest of your deck. It's the first of four guides covering the full Marvel Super Heroes universe on our blog; the companion Commander set, the reskinned Marvel Universe staples, and Marvel's Spider-Man each get their own dedicated guide, linked at the end.
Thanos, the Mad Titan — The Set's Signature Mythic
Thanos is a three-mana {R}{W}{B} legendary 4/4 with deathtouch and lifelink — already a solid rate before you get to the headline ability. His Power-up costs {C}{W}{U}{B}{R}{G}: it puts two +1/+1 counters on him, then you choose odd or even and destroy every other creature whose mana value matches. The MTG equivalent of the snap, and a genuine one-sided board wipe if you build your own curve around the opposite parity.
Because Power-up's cost is reduced by the permanent's own mana cost when activated the same turn it entered, casting Thanos and immediately snapping is far more achievable than the six-symbol cost suggests. He is one of the most in-demand cards in the set among players building around him, and a natural centrepiece for an Infinity Stone deck.
Browse our Thanos, the Mad Titan proxies — the same gameplay role for casual tables, at a fraction of the collector-market price.
The Mind Stone — One of the Set's Most Valuable Cards
One of the Infinity Stones, The Mind Stone is a legendary artifact built around the set's harness designation and the returning ∞ ability: once it is harnessed, its hidden power becomes active. At the time of writing, its premium versions sit at the very top of the Marvel Super Heroes price charts.
As of late August 2026, standard versions sit in the high double digits, while premium Collector Booster treatments can reach well into four figures. The borderless Gauntlet foil has been tracked around the $1,500–1,700 range, and the cosmic foil textless version has fewer than 150 copies printed.
Get The Mind Stone as a proxy and put those four figures toward the rest of your collection.
Mjölnir, Hammer of Thor — The Set's Best Equipment
Mjölnir enters as removal — dealing four damage to a creature — and then doubles all damage dealt by whatever it equips. The catch is flavour-perfect: it uses the set's equip worthy cost, a dramatically cheaper equip rate that only a legendary red and/or white non-Villain creature you control can use. Thor naturally qualifies for that cost; anyone else has to pay through the nose.
It is one of the strongest and most flavourful Equipment cards in the set, and a natural fit for Boros Equipment and Voltron decks where legendary red or white creatures are plentiful. Browse the Mjölnir proxy.
Cosmic Cube — A Card-Advantage Engine With Ward
Cosmic Cube carries ward, and whenever you attack it looks at the top six cards of your library, letting you cast one with mana value up to your greatest attacking creature's power — for free. It scales directly with how big your board gets, and can snowball out of control fast in a deck built to attack every turn.
Browse the Cosmic Cube proxy for any deck that wants to turn combat into card advantage.
Ultron, Artificial Malevolence — An Artifact-Copying Engine
Whenever another nontoken artifact you control enters, Ultron lets you pay a cost to create a token copy of it — and if that copy isn't a creature, it becomes a 2/2 Robot Villain creature on top of its other types. A strong payoff for any deck already leaning into artifacts, doubling up your best equipment, Treasures, or utility pieces turn after turn.
Browse the Ultron proxy for your artifact shell.
Doctor Doom — A Board Presence and Value Engine
Doctor Doom enters with two 3/3 colorless Robot Villain artifact creature tokens named Doombot, becomes indestructible as long as you control an artifact creature or a Plan, and draws you a card at the beginning of your end step at the cost of 1 life. That makes him both a board presence and a steady value engine.
His classic comic-cover treatment has been among the set's sought-after collector versions, with premium foil printings carrying a clear market premium over the standard card. Browse our Doctor Doom proxies.

Why Proxy These Cards Instead of Buying the Originals?
Marvel Super Heroes shows the widest price spread of almost any recent set. The Mind Stone alone runs from high double digits for a standard printing into four figures for the premium Collector Booster treatments, and considerably higher for the cosmic foil — all of them functionally the same card once it hits the table. That gap is entirely collector-market demand on treatments and scarcity, not anything Wizards charges for a booster pack.
A high-quality proxy lets you enjoy the same gameplay role at casual tables — while the chase originals can sit safely in a collection instead of getting shuffled, bent, and spilled on every game night. We go deeper into that logic in our guide on hybrid proxy decks.
Responsible Proxy Use
As with every proxy card, transparency matters. These proxies should be used for casual play, deck testing, collection, or display — not to deceive players, stores, marketplaces, collectors, tournament organisers, or authentication services.
If a proxy card is ever shown, traded, gifted, sold second-hand, or otherwise transferred to another person, its unofficial nature must be clearly disclosed. High-quality proxies are at their best when they make casual games more accessible, not when they are misrepresented as original cards.

Frequently Asked Questions
What is the most expensive Marvel Super Heroes card?
The Mind Stone. Its standard-frame printing is comparatively affordable, but premium Collector Booster treatments reach well into four figures, and the cosmic foil textless version — with fewer than 150 copies printed — goes considerably higher still.
How does the Power-up mechanic work?
Power-up is a special kind of activated ability that can only be activated once per permanent. If you activate it during the same turn that permanent entered the battlefield, the ability's cost is reduced by that permanent's own mana cost — which rewards leaving mana open on the turn you deploy your key creatures.
If a power-up ability has targets and all of them become illegal before it resolves, the ability does not resolve — but it still counts as having been activated, so you cannot activate that power-up ability again for that permanent.
Is there more than one Marvel-themed Magic set?
Yes — four, in fact. Marvel Super Heroes is the Standard-legal main set covered here. Marvel Super Heroes Commander is the Eternal-legal companion set. Marvel Universe reprints classic Magic staples with Marvel names and art. And Marvel's Spider-Man was the earlier, smaller crossover. Each has its own dedicated guide, linked below.
Are these proxy cards tournament-legal?
No. Proxy cards are intended for casual play, deck testing, collection, and display — not for sanctioned events or official tournaments. Always check with your playgroup, store, or event organiser before using proxies.
