Throughout Marvel Snap, players will collect more and more cards, which are themed after various characters in the Marvel multiverse. Within these cards, there are several different levels of Energy Costs, with 6-Cost cards being some of the most important in the entire virtual card game. That's because, in Marvel Snap, there are generally six rounds, meaning 6-Cost cards are usually the very last cards played in a match.
That said, fans will want to make sure that they're using the best 6-Cost cards in the game, and not falling into the trap of using 6-Cost cards that don't have a substantial use in Marvel Snap's meta just yet.
8 Agatha Harkness
Although some cards retain a large amount of Power in Marvel Snap, that fact alone doesn't make them impressive cards to use in a match. Agatha Harkness is one great example of that, as her card withholds a grand 14 Power.
Although she may have that much Power, Agatha Harkness' unique ability states that Agatha starts in the player's hand and plays their cards for them. Essentially, Agatha Harkness creates an AFK-esque deck as it plays cards for the player. But, without proper control, Agatha may consistently lose games, rendering her Power useless.
7 Spectrum
Spectrum used to be one of the most popular types of 6-Cost cards for players to use in their decks, especially early Ongoing decks. Spectrum is a 6-Cost card with only 5 Power, meaning that she is comparably weak to other higher-Costing cards.
Spectrum's On Reveal ability also isn't as significant enough as other cards to be considered crucial for synergistic combinations. On Reveal simply gives other Ongoing cards (like Iron Man) +2 Power, which isn't enough to cause a magnificent breakthrough in Power.
6 Orka
Orka has the same sort of Ongoing ability as Namor, making the two an undeniable pair of independent powerhouses; although, it is that one characteristic that makes the two fairly weak when compared to others.
Orka already has an exceptional 11 Power, but his Ongoing ability states that if there aren't any other friendly cards at the location, Orka gains +5 Power. This may bring Orka up to 16 Power, but not being able to have other cards at Orka's location makes it difficult to use effectively.
5 Destroyer
Destruction cards are some of the best combinations of characters in Marvel Snap, though there are a few exceptions. Destroyer is one of those exceptions, as its On Reveal ability proves too powerful to make complete use of.
Destroyer, being a 6-Cost card with 15 Power, has the On Reveal ability that destroys all other friendly cards. Though this ability is nice when paired up with cards that need to be destroyed, it's based on luck to ensure those cards are pulled at the right times, making Destroyer decks unreliable.
4 Leader
Leader used to rule the Marvel Snap community after more and more gamers were granted access to the Pool Three card, but since then, it has fallen to the bottom of the 6-Cost card tier list. For one, Leader only has 2 Power, making him one of the weakest 6-Cost characters in the entire mobile and PC card game. Secondly, Leader's On Reveal ability isn't as reliable as others.
That's because Leader's power allows him to copy the highest Powered card that the enemy played on the player's side of the location. Though this can be useful sometimes, the ability is too unpredictable to be meta.
3 Helicarrier
The Helicarrier is one of the most unreliable cards in all of Marvel Snap, save for those fans who enjoy using cards that put randomized cards into their hands, such as Agent 13. Helicarrier may have 10 Power, but its proficiency falls into being discarded.
When the card is discarded, Hellicarrier adds three random cards into the player's hand. For a 6-Cost card, Hellicarrier's ability doesn't provide enough quality to be considered valuable in any sort of deck, aside from having ample synergy with The Collector.
2 Doctor Doom
Doctor Doom stands out as one of the most powerful villains that present themselves in the Marvel universe. But, when it comes to Marvel Snap, Doctor Doom doesn't deliver as much as fans would have liked him to.
Doctor Doom can supply a location with a minuscule amount of 5 Power on his own (which isn't a lot). While he also has the On Reveal ability to pull two Doombots with 4 Power to each of the other locations, he just doesn't grant enough of an emphatic force to synergize, strategize, or generally use in Marvel Snap.
1 Arnim Zola
Not many characters in Marvel Snap withhold 0 Power, but when they do, fans can usually understand that they maintain a robust proficiency of some sort. Unfortunately for Arnim Zola, his On Reveal ability doesn't counteract the fact that his card only has 0 Power. When Arnim Zola is played onto a location, he destroys a random friendly card that is already at said location and then copies it onto the other locations.
Of course, with severely potent cards like Venom and Ronan (both are capable of holding immense Power), Arnim Zola can help take two locations. Simply put, Arnim Zola's destructive ability isn't just too unpredictable regarding locations with more than one friendly card but also irrelevant with cards that don't even have plentiful Power.
Marvel Snap is available on PC and mobile devices.
