Marvel Snap, the mobile sensation using the iconic Marvel characters, uses simple rules to create a fast-paced, action-packed gameplay loop. Of course, as with many card games, the big bosses are some of the most exciting parts of the game.
You get energy every turn in Marvel Snap, as in Heartstone and many other card games. Generally, you won't get to drop your most expensive card, the "boss" of your deck, until turn six. While none are bad, some outshine the rest in terms of Power.
Updated on February 19, 2022, by Doruk Kaptan: Marvel Snap is ever-evolving, introducing new cards, balancing old ones, and doing their best to maintain a healthy meta-game. One thing that has remained exciting since the game's launch is the 6-cost boss cards that each deck aims to end on.
These cards range from Ultron to Galactus himself and can be the end goal for many decks. Their effects are usually game-changing, and they can easily swing games on their own. With a constant influx of new cards, here are the best 6-cost cards in Marvel Snap as of now.
15 Arnim Zola
Arnim Zola is a rather unknown character from the Marvel Multiverse. While he has been adapted in some way in the Captain America movies, it's a large departure from his comic book portrayal. This 6/0 card may seem like a detriment at first, but it can lead to some amazing combos.
Arnim Zola destroys a random friendly card you have at his location on reveal. Then, you add copies of it to other locations. This is an incredible effect, especially when combined with strong On Reveal cards such as Black Panther or just big cards like The Infinaut.
14 Ultron
Ultron is a card that's been in the game for a while without much success. That is until the players paired him up with Patriot, a card that buffs up other cards without abilities.
On Reveal, Ultron creates four 1-Power Drones at each other location. These are cards without abilities, and all cost one. That means your Drones will be buffed up by both Patriot and Kazar. This combo alone could win you the game by itself, and Ultron has decent stats himself with eight Power.
13 Apocalypse
Apocalypse is a Pool One card, meaning you're quite likely to get him early on. Apocalypse has seldom seen play for a long while, but with each new Pool and Discard deck getting more and more optimized, Apocalypse became quite the powerhouse. The Discard support seems to be neverending.
This 6/8 card returns to your hand with +4 Power if it's ever discarded. This means that throughout the span of a game, it's very likely to gain a few buffs before you have a huge beater for your final turn push. Apocalypse works great with The Collector, too, as it adds itself back to the hand from your discard pile.
12 Knull
Speaking of cards that act as the boss of old strategies, Knull is the best boss a destruction-focused deck can find. It has the Ongoing effect to set its Power to the combined Power of all destroyed cards. This means that a deck that focuses on destruction effects can absolutely make a huge Knull consistently.
Knull fits the deck perfectly, as the older "boss" card was Destroyer, which required some protection, such as Armor. However, Knull has zero drawbacks with an incredible Power potential. It makes destruction decks infinitely more powerful and consistent with little work.
11 Heimdall
Yet another boss card that shines bright thanks to the small cards surrounding it is Heimdall. On Reveal, Heimdall moves all of your cards to one location to the left. When combined with cards like Vulture, Human Torch, and Kraven, this can make for a very explosive turn six.
The strategy requires some thinking to optimize your card distribution and can sometimes brick on high-end cards on early turns, but moving all the right cards on turn six is incredibly satisfying and fun. Heimdall also has decent stats, adding to the strategy's consistency.
10 Leader
Leader, the nemesis of the Hulk, is an exciting card. Unfortunately, it only has a power of 4, comparable to certain one and two-cost cards. However, his effect is something else entirely. On Reveal, Leader will copy all cards your opponent played on the location to the right of Leader's location this turn to your side.
This is quite a strong ability, potentially matching whatever Power push your opponent does on their last turn. Leader used to be so good that he warranted a nerf. While situational in its current form, Leader can secure a game if you're ahead on turn five, which makes it worth including in certain decks.
9 The Infinaut
The Infinaut is the current record holder for the highest base Power on a card. With a whopping 20 Power, it leaves many other godlike characters in its shadow. Unfortunately, it has a sizable and unique drawback — you can only play this card if you didn't play a card last turn.
While that's quite the detriment, it's not enough to make The Infinaut unusable. You can frontload your deck with low-cost cards with swarming capabilities and skip your fifth turn. That would mean you have a swing of 20 Power in the last turn, potentially winning you a contested location. While it is just a big guy with zero additional effect, The Infinaut is the best card at doing that.
8 Destroyer
Destroyer does precisely what it says on the tin, pun intended. It has a massive body with 14 Power, and on reveal it destroys your other cards. While that may seem really bad initially, there is a case for it.
Marvel Snap has many good cards that either ignore, want, or benefit from destruction. If you build a dedicated deck where the destruction of your cards is no issue, slapping a big card like the Destroyer on your last turn is nothing but advantageous.
7 Odin
Odin, the King of Norse Gods, is one of the more interesting six-cost cards in the game. It has a Power of eight, which is lower than many other high-cost cards. As with many other low-power cards on this list, though, he compensates with his ability.
On reveal, Odin activates the other On Reveal abilities at the same location. These effects can be fantastic, but are balanced with how they are one-and-done. Odin gives you a second round of using those abilities on your last turn. While strong, it feels like a win-more card and less of a game-changer.
6 Hela
Hela, the Norse Goddess of Death, also appears in Marvel Snap as a six-cost, six-Power card. While she has lower Power compared to other cards of the same cost, she makes up for it through her ability.
On reveal, Hela lets you distribute all your discarded cards to random locations. When used in a dedicated discard deck, with cards like Blade, Swarm, and Gambit, Hela can quickly fill your whole board and let you push for a game-winning final turn. The random placement is the only thing that slightly hurts Hela's usability.
5 America Chavez
America Chavez can be summed up in one word: reliable. This 6/10 is not the strongest nor has the most significant effect, but it's always there for you. Marvel Snap is a fast-paced game, with each turn mattering immensely. Luckily, Chavez helps you with consistency, only being drawable on turn six.
That means, while it's not the strongest six-cost card in the game, you'll never brick on it during early turns. Nothing feels worse than sitting on high-cost cards for a turn or two early on, and with America Chavez, your chances of living that nightmare are considerably lower.
4 Onslaught
Onslaught is potentially one of the most powerful cards in the game. To begin with, it has a good seven Power. However, his real deal is the ability, without a doubt. Onslaught has an Ongoing effect that doubles other Ongoing effects at its location.
Ongoing effects are among the strongest in the game's current state, and doubling them can be incredibly useful. Many cards that add or gain Power, such as Ant-Man, Captain America, Mister Fantastic, and many more, do so with Ongoing effects. Doubling them on a swing location can quickly change a defeat into a victory.
3 Spectrum
Speaking of Ongoing effects, another boss that fits the bill is Spectrum. On reveal, Spectrum gives your Ongoing cards +2 Power. Having low Power when compared to its peers hurts, for sure.
Despite this, Spectrum can buff all locations to extraordinary heights on your last turn if part of a dedicated Ongoing effect deck. While both Spectrum and Onslaught are great choices to end with an Ongoing strategy, Spectrum's ability to buff across the map and not just one location makes her just a bit better in general.
2 Doctor Doom
Doctor Doom is one of the most well-known and beloved villains in Marvel Comics history. The good news is that he's mighty in Snap as well. He's a five-Power card, meaning his Power is on the lower end of the six-cost spectrum. However, Doctor Doom was never a character to brawl his way to victory anyways...
Doctor Doom adds two five-power Doombot cards to each other locations. Basically, you get to add five Power to each location as long as you have the available spaces. That's a perfect effect, as many last-turn plays affect one location or two at most. Buffing them all at the same time is such an excellent way to end a game.
1 Magneto
Magneto, the iconic villain of the X-Men, has one of the most vital abilities in the game, combined with a sizable Power. Even if it were a vanilla card, Magneto would match The Hulk in terms of usability. However, Magneto is powerful, thanks to his ability.
On reveal, Magneto moves all opposing three and four-cost cards to his location. That is a fantastic effect, considering how many cards of those costs are the difference makers in many games. Even if you use Magneto as a decoy and put him in a location by himself, it can weaken the other locations enough for you to win in both, securing you the victory.
