Onslaught is a very powerful card in Marvel Snap with a lot of versatility. Onslaught's Ongoing ability is to double the effects of all other Ongoing abilities at this location. This means, under the right circumstances, Onslaught could double the effects of up to three other Ongoing cards. The potential for this is truly limitless, and whether you are stacking Wong on top of Mystique or trying to break the game by using Iron Man, Onslaught is a must-include for several deck archetypes.
So, if you are ready to start using Onslaught, you've come to the right place. This article will cover the best Onslaught decks in Marvel Snap, including deck lists, strategies, and more!

Best Onslaught Decks In Marvel Snap
The best Onslaught decks in Marvel Snap are those with powerful Ongoing effects that can be doubled. Because Ongoing cards are so prevalent in Marvel Snap, there are tons of possible uses for Onslaught. However, Onslaught is usually played in decks that use buffing or debuffing cards, such as Patriot, or in decks that like to stack Wong effects.
Onslaught Patriot Deck
Patriot decks are arguably where Onslaught sees the most play. Using Patriot, Mystique, and Onslaught together ensures your textless cards receive a huge buff to their overall power, which will usually be enough to win the game. The only downside with this is that players will need to stack all of their Ongoing effects on top of one another at the same location for the biggest benefit. This opens you up to counterplay from cards like Enchantress.
Onslaught Patriot Deck List:
- Wasp
- Misty Knight
- Mister Sinister
- Shocker
- Mystique
- Patriot
- Brood
- Cyclops
- Super Skrull
- Blue Marvel
- Onslaught
- Ultron

Onslaught Exodia Deck
The Exodia deck is named as such because, after acquiring all pieces of the puzzle in your hand, you essentially win the game. This idea with this deck is to stack as many Wong effects on top of each other using the base card, Mystique, and Onslaught. Then, you can unleash fury on your opponent with whatever game-winning strategy you like. The most common option here is to use Gambit to destroy the entirety of your opponent's board. However, Luke Cage and Hazmat work just as well.
