5 best Marvel Snap Toxin counter decks

Marvel Snap's Toxin counter decks are focused on countering his ability to return cards at his location and gaining +2 power for each card returned. This not only clears the board for Toxin, but also makes the opponent re-play returned cards. This often disrupts tempo and synergy.

Countering Toxin is all about building a deck that can either nullify the On Reveal effects or simply outpower his power gain across the board. To get you started, we have compiled a list of five Marvel Toxin counter decks, their synergies, and key cards.

Here's a look at the control counter deck for Toxin in Marvel Snap:

Ant-Man (Cost 1/Power 1)
Shadow King (Cost 2/Power 3)
Maximus (Cost 2/Power 6)
Cosmo (Cost 3/Power 3)
Shang-Chi (Cost 4/Power 3)

Enchantress blocks any Ongoing cards that can strengthen Toxin’s combination, while Armor protects important cards from destruction, preserving your pace.

2) Power ramp

The power ramp counter deck to Toxin comprises:

Korg (Cost 1/Power 2)
Baron Mordo (Cost 2/Power 3)
Scorpion (Cost 2/Power 2)
Maximus (Cost 2/Power 6)
Black Widow (Cost 3/Power 5)

Killmonger (Cost 3/Power 3)
Rockslide (Cost 4/Power 6)
Darkhawk (Cost 5/Power 3)
Blue Marvel (Cost 5/Power 3)

Black Widow jams the opponent’s draws with Widow’s Bite, and Baron Mordo turns a low-cost card into a higher cost. Rockslide and Korg fill the opponent’s deck with Rocks, lowering card rarity. Darkhawk benefits from this by acquiring power from their flooded deck. This synergy not only counters Toxin’s power ramp, but also disrupts your opponent’s mid-game.

Squirrel Girl (Cost 1/Power 3)
Mantis (Cost 1/Power 2)

Squirrel Girl and Brood flood the locations while Debrii blocks lanes with rocks making it difficult for Toxin to place himself or even if he does he returns unnecessary rocks to hand. Killmonger clears 1 cost cards when it is beneficial for him, which can stop him from stacking power. Blue Marvel buffs cards across the board and applies pressure evenly over all lanes.

Polaris and Spider-Man disrupt enemy placements to stop Toxin from taking advantage, and Miles Morales gives strong power at a low cost. This strategy keeps the pressure on Toxin, preventing its lane dominance.
