Moonstone isMarvel Snap’s newest Ongoing card, capable of copying the text of your other 1-, 2-, and 3-Cost Ongoing cards in her lane. Think of her as an enhanced version of Mystique. However, building a strong deck around this powerful yet fragile card is no easy task, earning her the nickname “the Glass Cannon ofMarvel SNAP.”
After some testing, I’ve found that the two best decks for Moonstone are Patriot and Tribunal setups. This guide will walk you through how to build and optimize both decks effectively. If you’re still on the fence about adding Moonstone to your collection, there’s also a brief review at the end to help you decide.

Moonstone (4–6)
Ongoing: Ongoing: Has the Ongoing effects of your 1, 2, and 3-Cost cards here.
Release: August 02, 2025
The Best Deck for Moonstone
Moonstone thrives in decks where she plays a supporting role rather than being the primary win condition. For a reliable setup, consider using Moonstone in a Patriot-Ultron deck. Focus on having her copy one or twokey Ongoing effectsrather than relying too heavily on her ability.
To construct a Moonstone deck with Patriot and Ultron, pair them with these cards: Brood, Mystique, Dazzler, Mockingbird, Ant-Man, Iron Man, Squirrel Girl, Blue Marvel, and Mister Sinister.

Moonstone Deck Synergies
An Alternative Deck for Moonstone
In my testing, I found that Moonstone offers incredibly fun gameplay when paired with Onslaught andThe Living Tribunal. If you prioritize excitement over consistency, use Moonstone as a win condition alongside these cards: Onslaught, Living Tribunal, Mystique, Magik, Psylocke, Sera, Iron Man, Ravonna Renslayer, Captain America, Howard the Duck, and Iron Lad.

Here’s the ideal play line:
In this setup, Psylocke and Sera are discount providers, allowing you to play key cards earlier. Magik extends the match, enabling the play of Onslaught, followed by The Living Tribunal. Meanwhile, cards like Captain America and Iron Lad act as backups in case you don’t draw the necessary cards in time.
Many players had predicted the trio of Moonstone-Onslaught-Tribunal would become a staple in the metagame after Moonstone’s release, with some even considering it her natural fit. However, few anticipated that she would have an arch-nemesis in this setup: Super Skrull.
How to Counter Moonstone
Unfortunately for Moonstone players,she’s an easy target for Super Skrull. Since her release, many players have been adding Super Skrull to their decks, anticipating Moonstone decks, and it works! Enchantress, Rogue, and Echo also count as counters to Moonstone, leaving her quite vulnerable.
The biggest drawback of Moonstone is that she absorbs the abilities of cards in her own lane. So, unless you hide her behind cards like Invisible Woman, your opponent can easily shut down that lane with Enchantress, Echo, or Rogue. Alternatively, they could play Super Skrull in another lane to neutralize your strategy.
Is Moonstone Worth It?
Moonstone is worth yourSpotlight Keysfor a few reasons: 1) Her solid ability will only become more valuable as more Ongoing cards that synergize with her are released; 2) She’s in a Spotlight Cache alongside two other Series Five cards, reducing the risk of unsuccessful pulls; and 3) She’s one of the most nostalgic new cards to joinMarvel Snap. If you miss the days of pulling off crazy combos that add massive numbers to the board, Moonstone is a card worth getting.
