Cosmo is one of the most powerful cards in Marvel Snap. Despite being nothing more than an average three-cost three-power card, Cosmo stands out from the crowd for having one of the most impactful abilities in the entire game. Cosmo's Ongoing effect prevents all On Reveal abilities from occurring at the same location. Not only does this shut down a large number of powerful decks in Marvel Snap, but Cosmo cannot be countered by any card in the game. The only card which shuts down enemy Ongoing abilities other than Leech is Enchantress, which, you guessed it, can only do so with her On Reveal ability!

So, if you are ready to start using Cosmo in Marvel Snap, you've come to the right place! This article will cover the best Cosmo decks in Marvel Snap, including deck lists, strategies, and more!

Best Cosmo Decks In Marvel Snap

The best Cosmo decks in Marvel Snap are all of them! Joking aside, there is a reason why many people state that Marvel Snap's deck size actually only consists of ten cards. Players will most likely want to add Cosmo and Shang-Chi to a deck and then start deckbuilding!

Cosmo is great in control decks, as it can easily shut down enemy strategies. However, Cosmo is just as powerful in an aggressive deck, providing much-needed protection against an enemy Shang-Chi.

Red Skull Deck

Cosmo is great at protecting your high-power Red Skull and Taskmaster from an enemy Shang-Chi. By playing Armor in one lane and Cosmo in another, there is little your opponent can do other than retreat. There is a reason the Shuri Red Skull deck has been at the top of the meta for as long as it has, and, even despite the most recent nerfs to Red Skull, do not expect this deck to be going anywhere anytime soon. 

Red Skull Deck List:

• Sunspot
• Zero
• Titania
• Armor
• Lizard
• Cosmo
• Polaris
• Shuri
• Taskmaster
• Vision
• Red Skull
• She-Hulk

Control Deck

Cosmo functions excellently in control decks as it works alongside other tech cards to shut down all of your opponent's strategies. 

Control Deck List:

• Nova
• Angela
• Sentinel
• Mysterio
• Lizard
• Cosmo
• Killmonger
• Shang-Chi
• Sera
• Aero / Enchantress
• Spider-Woman

Ongoing Deck 

Because Cosmo has an Ongoing ability, he works well in decks that choose to run Spectrum. Additionally, Cosmo is great at preventing Destroyer from destroying your other cards.

Ongoing Deck List:

• Ant-Man
• Armor
• Colossus
• Lizard
• Captain America
• Cosmo
• Warpath
• Attuma
• Professor X
• Klaw
