Mister Negative is a supervillain who normally appears as Spider-Man’s adversary. He has the power to invert anything he touches. This power is translated perfectly into his card in Marvel Snap, so one of the most powerful cards that you can get is Mister Negative, which is found in Pool 3 of the game.
- Mister Negative has the power to invert your deck, swapping the card’s power and cost in doing so.
- When paired with Jane Foster, Mister Negative is capable of creating and drawing out zero-cost cards.
- Putting Mister Negative in a deck with many zero-power cards is the deadliest deck composition out there.
- Author’s Note: After going through Marvel Snap for several weeks on Steam, I feel confident going into the topic with thorough experience.
Here’s information on all the cards in Mr. Negative’s deck:
Name | Cost | Power | Abilities |
---|---|---|---|
Hawkeye | 1 | 1 | On Reveal: Grant +2 Power if you play a card here on the next turn |
Mantis | 1 | 2 | On Reveal: You can draw a card from your enemies deck if they play their card at this location |
Adam Warlock | 2 | 0 | You can draw a card if you are winning this location at the end of each turn |
Agent 13 | 1 | 2 | On Reveal: Grants you a random card |
Psylocke | 2 | 1 | On Reveal: Gain +1 Energy on the next turn |
Ironheart | 3 | 0 | On Reveal: Grant +2 Power to three random cards at this location |
Morph | 3 | 0 | On Reveal: Turn into a duplicate of any random card at your enemy's hand |
Jubilee | 4 | 1 | On Reveal: Play your deck card at this location |
Mister Negative | 4 | -1 | On Reveal: Swap and change all the Cost and Power of all your deck cards |
Iron Man | 5 | 0 | On Reveal: Your Power is doubled |
Jane Foster | 5 | 8 | On Reveal: Draw every card from your deck that has zero-cost |
Arnim Zola | 6 | 0 | On Reveal: Eliminate a friendly card and add a duplicate of it on another location |
Mister Negative Card
He is a 4 Cost and -1 Power card (It may say 4 power in some variants of the card). Although seemingly unimpressive, he packs quite a significant punch in the form of his ability.
His ability is that On Reveal, he swaps the power and costs of all cards in your deck, excluding the cards you already have in your hand. This ability has the power to convert every zero-power card in your deck into a zero-cost card! This allows you to play multiple cards each turn without having to worry about energy costs.

Every Card’s Role Explained
There are many different types of abilities in Marvel Snap; however, this deck only has two. On Reveal, abilities are triggered when the card is played and revealed to the opponent. Ongoing abilities have a prolonged effect and will continue to affect the game as long as the card is in play.
Hawkeye

However, that allows you to play Mantis at the same location since you’ll trigger Hawkeye’s ability as well as bait your opponent into activating Mantis’s ability. Hawkeye is a starter card, so you won’t have to unlock him.
Mantis

Since your opponent is likely also going to try and control that area, it’s a good idea to try and counter your opponent. Mantis can be unlocked in Pool 1 at Collection Level 18-214.
Adam Warlock

Agent 13:

Psylocke

Ironheart

Morph

Jubilee

Mister Negative

Iron Man

Jane Foster

Arnim Zola

Main Deck Strategy
Now that you’re all set up and well-versed with each card in the deck, let’s go through how you should play with this deck in hand.
To start, play Hawkeye so that you can trigger his ability by the next turn. By playing Hawkeye, you’ve let your opponent know your next move so you need to think accordingly. Your opponent knows you’ll be playing your next card in the same location as Hawkeye so be ready for it. Your best move would be to play Psylocke at the same location as Hawkeye so that you can have an extra energy point in the next turn. However, if you don’t have Psylocke in hand, play Mantis as she’ll counter any card your opponent plays on that location.
Next up, you play Mister Negative. The sooner you can get Mister Negative out the better, as he’ll invert all your cards and we’ll get all the zero-cost cards. The best-case scenario would be to have Jane Foster in hand and then use Mister Negative otherwise, Jane becomes a dead draw with a cost of 8. However, if you don’t have Jane Foster in your hand just yet, feel free to play any other card to wait it out. After playing Mister Negative, you can play any card you have on hand in the fourth turn.
On the fifth turn, we’ll shake things up and play Jane Foster. In doing so, we’ll draw out every zero-cost card in your deck. After inverting all your cards, 5 of your cards are zero-cost so they will all be made available in a single turn. At this point, you can go all out and play your heavy hitters however you like, and make sure to go out with a bang.
Secondary Strategy
In the very possible scenario where things don’t go as planned and you have to steer off-course, it’s always good to have a backup strategy in mind.
At the very beginning of the match, analyze the first location. If the location provides a bonus to whoever’s controlling it, it’s safe to assume that your opponent will play a card there. With this knowledge, you can play Mantis on the first turn and rest assured that her ability will be activated. With her ability activated, you’ll get your hands on one of the opponent’s cards. This will give you an insight into your adversary’s strategy, and you can prepare accordingly.
If you don’t have Psylocke on the second turn, use Adam Warlock. He’ll let you draw an extra card on the next turn, which might help you draw Mister Negative or Jane Foster. If every strategy manages to fall apart and you don’t have Mister Negative in hand by the fifth turn, play Jubilee.
She’ll play a card straight from your deck, and this card might just be Mister Negative. Thankfully, even if it isn’t Mister Negative, you still have a lineup of strong cards that can sway the game in your favor.
My Personal Take On Mister Negative
Mister Negative has one of the strongest abilities in Marvel Snap, and the best thing about it is that you can utilize his ability on hundreds of powerful cards like the ones I’ve included in my decks. However, in almost any Mister Negative deck, one caveat is painfully clear – if you don’t get Mister Negative in your hand during a match, you’ve lost.

I’ve said in multiple guides that if a character’s abilities are unique, then there’s almost no appropriate backup, which is a terrible strategy in Marvel Snap. As such, if you don’t get Mister Negative in a match, you can’t use some other card in your deck as a replacement since they can’t replicate the same ability. So, I’d recommend using Mister Negative if you’re extremely lucky, or wait for a card to release that can take advantage of high-Cost and low-Power cards like he does.
When starting with Marvel Snap, you don’t understand how to utilize each beginner card fully. Even if you’re an experienced player, you still need a hand getting used to all the ins and outs of each card. By the time you’re at the later stages of the game, you’ll have a ton of cards you don’t know what to do with, so hopefully, my Mister Negative deck will help you in Marvel Snap.
Mister Negative is an extremely strong card despite not being easy to use. He requires a lot of thinking to be played right and might not be everyone’s favorite right out of the gate. He takes some getting used to, and you can positively say that with enough practice, he can help you out in the trickiest of situations.
