Quick Navigation
Moonstone stands as Marvel Snap's latest Ongoing card, designed to replicate the abilities of your 1-, 2-, and 3-Cost Ongoing cards within her lane. She functions like an upgraded Mystique, though constructing a reliable deck around this potent yet fragile card presents significant challenges. This vulnerability has earned her the community title "the Glass Cannon of Marvel SNAP."

Through extensive testing, I've determined that Patriot and Tribunal configurations yield the strongest performance with Moonstone. This guide details effective construction and optimization techniques for both archetypes. For those undecided about acquiring Moonstone, a final section provides insights to inform your choice.

Optimal Moonstone Deck Construction

Moonstone performs best in decks where she enhances existing strategies rather than serving as the primary win condition. For consistent results, integrate her into a Patriot-Ultron framework. Focus on having her copy one or two crucial Ongoing abilities instead of over-relying on her effect.
To assemble this Moonstone-Patriot-Ultron combination, include these key cards: Brood, Mystique, Dazzler, Mockingbird, Ant-Man, Iron Man, Squirrel Girl, Blue Marvel, and Mister Sinister.

Moonstone Deck Synergy Breakdown

Optimal play sequence:
- Utilize Psylocke to deploy Moonstone ahead of curve
- Stack Onslaught, Mystique, and Iron Man in her lane
- Conclude by distributing power across all lanes using The Living Tribunal
This configuration leverages Psylocke and Sera for cost reduction, enabling earlier deployment of key cards. Magik extends match duration to accommodate Onslaught and Living Tribunal plays. Meanwhile, Captain America and Iron Lad provide backup options when essential draws are delayed.
Many players anticipated Moonstone-Onslaught-Tribunal becoming a meta staple upon release, with some considering it her natural home. However, few predicted her primary counter in this setup: Super Skrull.
Effective Moonstone Countermeasures
Moonstone players face significant vulnerability to Super Skrull. Since her introduction, many competitors have teched in Super Skrull specifically for Moonstone matchups, with considerable success. Additional counters include Enchantress, Rogue, and Echo, making her exceptionally exposed to disruption.
Moonstone's primary weakness lies in absorbing abilities from her own lane. Without protection from cards like Invisible Woman, opponents can easily disable her lane with Enchantress, Echo, or Rogue. Alternatively, they can deploy Super Skrull in another lane to nullify your strategic advantage.
Moonstone Value Analysis

Moonstone merits Spotlight Key investment for several reasons: 1) Her robust ability gains value as more synergistic Ongoing cards release; 2) She shares Spotlight Cache with two other Series Five cards, minimizing pull risk; 3) She represents one of Marvel Snap's most nostalgic additions. For players who enjoy executing complex combinations that generate massive board numbers, Moonstone delivers that experience.
