Moonstone, Marvel Snap's newest Ongoing card, copies the effects of your other 1-, 2-, and 3-cost Ongoing cards in her lane. Think of her as a boosted Mystique. However, building a deck around this powerful but fragile card—often called "the Glass Cannon"—presents a challenge.
After extensive testing, the two most effective Moonstone decks utilize Patriot and Tribunal strategies. This guide details building and optimizing both. A brief review at the end helps you decide if Moonstone deserves a spot in your collection.
Moonstone (4–6)

The Best Deck for Moonstone
Moonstone excels as a support card, not the primary win condition. A reliable strategy uses her in a Patriot-Ultron deck, focusing on copying one or two key Ongoing effects rather than over-relying on her ability.
This Moonstone/Patriot/Ultron deck includes: Brood, Mystique, Dazzler, Mockingbird, Ant-Man, Iron Man, Squirrel Girl, Blue Marvel, and Mister Sinister.

Moonstone Deck Synergies
- Set up buffs by playing Brood, Sinister, or Squirrel Girl.
- Use one lane for Patriot, Mystique, and Moonstone (ideally in that order).
- Play Ultron in the final round to maximize buffed power across locations.
- Iron Man, Blue Marvel, and Mockingbird provide backup power if needed.
An Alternative Deck for Moonstone
For a more exciting (though less consistent) approach, pair Moonstone with Onslaught and The Living Tribunal. Here, Moonstone becomes the win condition. This deck also includes: Mystique, Magik, Psylocke, Sera, Iron Man, Ravonna Renslayer, Captain America, Howard the Duck, and Iron Lad.

Ideal Play:
- Use Psylocke to play Moonstone early.
- Play Onslaught, Mystique, and Iron Man in her lane.
- In the final round, distribute power across lanes using The Living Tribunal.
Psylocke and Sera provide cost reduction, Magik extends the game, allowing for Onslaught and The Living Tribunal plays. Captain America and Iron Lad offer backup. While many predicted a Moonstone-Onslaught-Tribunal meta, Super Skrull emerged as a significant counter.
How to Counter Moonstone
Super Skrull effectively counters Moonstone. Since her release, many players have included him, anticipating Moonstone decks. Enchantress, Rogue, and Echo also neutralize her.
Moonstone's weakness is her reliance on her own lane. Unless protected (e.g., by Invisible Woman), Enchantress, Echo, or Rogue easily shut down that lane. Super Skrull in another lane also disrupts the strategy.
Is Moonstone Worth It?
Moonstone is a worthwhile Spotlight Key investment for several reasons: 1) Her ability will become more valuable with future Ongoing cards; 2) She's in a Spotlight Cache with two other Series Five cards, reducing the risk of poor pulls; and 3) She offers nostalgic, high-impact combo potential. If you enjoy powerful board-swinging combos, Moonstone is a great addition.
