Seven new cards. Inverted morality. One card that's going to make a lot of players very angry this month.
Marvel Snap's September season is built around the 2014 Marvel Comics crossover event Axis: Inversion, a storyline where the Scarlet Witch and Doctor Strange accidentally reversed the moral compass of nearly every hero and villain in the vicinity. Avengers went dark. Villains went soft. Carnage became a neighborhood protector. Developer Second Dinner has leaned fully into that concept, and the result is a card set where familiar names play completely differently than you'd expect.
Here's the lowdown on everything dropping this season.

The card everyone will be building around (and dreading)
Superior Iron Man is this month's Premium Pass card, and he's the one that's going to warp the meta. The morally inverted version of the armored Avenger carries an Ongoing ability that doubles both cost reductions and power increases applied to him. That's not a small tweak. That's a card that can snowball out of control fast.
The math gets alarming quickly. Play America Chavez and hit Superior Iron Man with a +3 power boost and he becomes a 5/13. Stack Gwenpool and Okoye to fish him out of your deck at full power, and you're looking at a Turn Six threat that most standard decks simply can't answer cleanly.
Here's the thing: the counters exist, but you need to plan for them. Shadow King resets his power to base. Enchantress wipes all Ongoing abilities at her played location. Rogue can steal the Ongoing outright. Mobius M. Mobius locks him at five-cost, which at least prevents some of the discount stacking. If Superior Iron Man starts dominating ladder, expect all four of those cards to see a sharp rise in play.
The rest of the Axis: Inversion roster
Anti-Polar Magneto headlines the Super Premium Pass and does something genuinely useful: his On Reveal drops one three- or four-cost card from your hand to each location. That opens up placement for cards with strict conditions like Cull Obsidian, Crossbones, and Drax, while also setting up late-game swings with Silver Surfer or Shang-Chi.
Red Onslaught arrives as the lead Series 5 Snap Pack card. He's a four-energy card that generates three random Ongoing abilities on reveal. The randomness is the point, and the risk. At four cost, a lucky roll could completely upend your opponent's plan. An unlucky one could do nothing useful at all.
Kluh, the inverted Hulk, has an On Reveal that gives a card in each player's hand -1 cost for every different cost value among cards currently in play. Play your cards in ascending order throughout the match and Kluh could turn a six-cost card into a freebie on the final turn.
Friendly Neighborhood Carnage is the most mechanically interesting card in the set. He moves all cards at his location one step to the right and gains +2 power for each card shifted. The key here is that low cost combined with that power scaling makes him a natural anchor for move-focused decks running The Human Torch, Dagger, and Spider-Man 2099. A full location shift could push him to genuinely threatening power levels without much setup.
Rogue: Scion of Division flips the original Rogue's ability in a useful direction. Instead of stealing an Ongoing from a card already in play, she steals the text of the highest-cost card in your opponent's hand. Drop her on Turn 4 or 5 and she becomes a direct counter to anyone running Knull or Onslaught builds.
Scarlet Witch: Queen of Chaos rounds out the new additions by adding a free, random skill card to your hand on the following turn. Free is free, but the randomness means she's more of a wildcard than a consistent win condition.
Two more cards and the locations to watch
Two additional Series 4 cards arrive mid-season. Entropic Havok drops September 16 and steals one bonus energy from your opponent each turn (if they have any), which is the kind of persistent pressure that can quietly decide close matches. The Inversion arrives September 28 with an On Reveal that flips the power of the lowest-power card at its location, turning positives negative and vice versa.
The two new locations tie directly into the season's themes. Stark Island premieres September 9 and gives a card in each hand -1 cost at the end of every turn, which pairs well with Superior Iron Man's discount-doubling ability. Jean Grey School arrives September 23 and makes all cards at that location moveable on Turn 5, opening up late-game repositioning for move deck players.
Draft Mode also returns this month with Sanctum scoring rules, running from September 28 through October 11. If you want to test the new cards without committing to a full deck build, that's your window.
What this means for gamers: the Axis: Inversion season is going to hit the meta hard, and Superior Iron Man is the card to watch. Check out gaming guides for deck-building resources as the community figures out exactly how broken he is in practice.
