How Diamondback Works in Marvel Snap
Diamondback is a 3-Cost, 3-Power card with the Ongoing ability: “Enemy cards here afflicted with negative Power have an additional -2 Power.”
This effect shines in decks that apply negative Power to enemy cards—a mechanic supported by several existing cards. Key enablers include US Agent, Man-Thing, Scorpion, Hazmat, Cassandra Nova, Scream, Bullseye, and others. To maximize her value, aim to affect at least two enemy cards in her lane, effectively turning her into a 7-Power threat.
However, be cautious of counters. Luke Cage completely nullifies her impact by removing negative Power, rendering her ability useless. Similarly, Enchantress and Rogue can disrupt her synergy by stealing or negating key effects.

While Diamondback may appear niche, she integrates well into multiple competitive archetypes—most notably Scream Move, Toxic Ajax, High Evolutionary, and Bullseye Discard. Among these, she finds her strongest footing in Toxic Ajax and Scream Move decks. Below are two optimized lists showcasing her potential.
Scream Move Deck
[Kingpin] [Scream] [Kraven] [Sam Wilson Captain America] [Spider-Man] [Diamondback] [Rocket Raccoon and Groot] [Polaris] [Doom 2099] [Aero] [Doctor Doom] [Magneto]

Series 5 Cards: Scream, Sam Wilson Captain America, Rocket Raccoon and Groot, Doom 2099
Scream and Rocket Raccoon and Groot are essential for this deck’s function. If you don’t own Sam Wilson, consider replacing him with another affliction card like Scorpion.
This deck revolves around board control and Power manipulation. Use Kingpin and Scream to pull and afflict enemy cards, then place Diamondback in the same lane to amplify the damage. Each afflicted enemy takes an extra -2 Power, making her lane extremely difficult to contest.
The back half of the deck focuses on late-game tempo with the Doom 2099 package. Cards like Aero, Doctor Doom, and Magneto benefit from low card counts in later turns, while Doombots and lingering afflictions boost your final Power total.

Toxic Ajax Deck
[Silver Sable] [Hazmat] [US Agent] [Luke Cage] [Rogue] [Diamondback] [Red Guardian] [Rocket Raccoon and Groot] [Malekith] [Anti-Venom] [Man-Thing] [Ajax]

Series 5 Cards: Silver Sable, US Agent, Red Guardian, Rocket Raccoon and Groot, Malekith, Anti-Venom, Ajax
This deck is one of the most powerful—and expensive—affliction-based builds in the game. While Silver Sable can be swapped for Nebula if needed, the rest of the Series 5 cards are nearly mandatory for optimal performance.
The core strategy is to maximize Ajax’s Power through negative Power effects. Cards like Hazmat, US Agent, and Man-Thing inflict debuffs that stack with Ajax’s ability. Diamondback enhances this synergy by weakening afflicted enemies even further.
Malekith can pull key cards like Diamondback or Hazmat into new lanes for Power spikes, while Anti-Venom provides a surprise boost in the final turns. Rogue is included as a counter to Luke Cage, which is expected to be heavily played during Diamondback’s release window. Since Luke Cage shuts down this entire strategy, Rogue offers crucial resilience.
Is Diamondback Worth Spotlight Cache Keys or Collector’s Tokens?
If you already own key affliction cards—especially Scream, Rocket Raccoon and Groot, and Ajax—then Diamondback is a valuable addition to your collection. She enhances several top-tier decks and offers consistent, high-impact plays.
However, if you don’t own the necessary synergistic cards or typically avoid affliction-based strategies, she may not be worth the investment. Her utility is highly conditional, and the decks she excels in are among the most resource-intensive in the game.
In short: Only pull for Diamondback if you’re committed to running affliction decks.
These are the best Diamondback decks in Marvel Snap. Whether you're amplifying Scream’s chaos or supercharging a Toxic Ajax build, Diamondback adds a sharp new edge to your strategy.
