How to Counter Diamondback
Diamondback has a major counter:Luke Cage. Playing him anywhere on the board nullifies her effect by removing all negative Power and restoring your cards to their base stats. While Enchantress and Rogue can also counter Diamondback, Luke Cage remains the strongest and most reliable option.
Is Diamondback Worth It?
If you playtoxic archetype decks, Diamondback is a must-have. She’s crucial for maximizing affliction damage and often serves as the primary win condition, swinging a lane by 11 Power—three from her own stats and eight from enemy debuffs.
However, if you’re missing key toxic synergies like Hazmat, Luke Cage, Ajax, or Man-Thing, investing in Diamondback may not be the best choice. Additionally, in the current meta, she struggles to shine due to the high number of Luke Cage players countering her effect. That said, her potential could improve as the meta shifts. If you decide to get her, view her as a long-term investment rather than an instant competitive powerhouse.
