The Marvel Universe is no stranger to magic and witchcraft, with heroes and villains alike using mystical powers to battle opponents, like Doctor Strange and Scarlet Witch, to name a few. But in Marvel Snap, another witch proves she is a notorious force—Scarlet Witch’s friend-slash-mentor-slash-foe, Agatha Harkness.

Agatha Harkness is a six-cost, 14-Power card with the ability that reads, “Agatha starts in your hand and plays your cards for you.” This is self-explanatory and could drive you away from playing it in your deck. You can take advantage of Agatha’s AI, too, given the right tools.

Here are the best Agatha Harkness decks in Marvel Snap.

One way to use Agatha’s controlling prowess is to include it in a deck where most cards do not rely on combos. This consists of the farm engine, where the main objective of the deck is to play cards as much as possible while boosting their Power in the process.

In this deck, you can include multiple low-cost cards with various control and offensive effects. This includes Ant-Man, which gains plus three Power if you have three other cards on the location where it is placed; Sunspot, which gains Power equal to your unspent energy per turn; Iceman, which gives plus one cost to a random card at your opponent’s hand; Korg, which gives a rock to your opponent’s deck; Squirrel Girl, which adds a one-Power Squirrel to each other location, and Rocket Raccoon, which has the ability that reads “On Reveal: If your opponent played a card here this turn, +2 Power.”

Scarlet Witch can also be added since it changes a location upon playing it. Morph, on the other hand, transforms as a copy of a random card in your opponent’s hand when you place it in a location. For the farm strategy to work, cards that boost your units are the key pieces for this deck. These are Ka-Zar, a four-cost, four-Power card that adds plus one Power to all your one-cost cards, and Blue Marvel, a five-cost, three-Power card that adds plus one Power to all your cards in play.

Cap off the deck with America Chavez, which is a six-cost, nine-Power unit you will always draw on turn six. The key to using this deck is simple—let Agatha take over.

Other win condition cards for the Agatha Farm deck

Aside from Agatha, who executes the overall strategy for this deck, the other win condition cards for this deck are:

  • Ant-Man
  • Ka-Zar
  • Blue Marvel

Ant-Man is the main one-cost card for this deck since it gains additional Power if Agatha manages to put three more cards in the location where she placed them. As for Ka-Zar and Blue Marvel, these cards will be your Power boosters—so I hope Agatha plays both cards when she draws them.

Agatha Discard

You can also use Agatha Harkness in a discard deck. Here, the primary goal is to get rid of Agatha while having the chance to bring her back to one of the locations just as a Power booster instead of having her pilot the deck.

You can use units that can discard cards from your hand, including Blade, Sword Master, Moon Knight, Lady Sif, and M.O.D.O.K. These cards can discard Agatha from your hand if the RNG favors your side.

Swarm can also be added to the deck since it can give you two zero-cost copies of it if it gets discarded. As for the cards that can bring discarded cards from your hand to your locations, you can play Ghost Rider, which summons one of your discarded units on the location where you played it. Hela, on the other hand, is a six-cost, six-Power unit that resurrects all the cards you discarded to random locations.

Some of the potential discard targets aside from Agatha and Swarm include Magneto, which is a six-cost, 12-Power unit that moves all opposing three and four-cost cards on the location where you played it, Apocalypse, which is a six-cost, eight-Power card that immediately returns to its owner’s hand after it gets discarded while having a plus four Power bonus every time this happens, and Giganto, which is a six-cost, 14-Power card that can only be played in the left lane. Finding an opportunity where you use Hela or Ghost Rider to summon Giganto after its been discarded could provide you with a huge power boost.

Again, the key to using this deck is to let Agatha play. But if it gets discarded, prioritize discarding as much as possible if you know you have the cards to return your discarded units.

Other win condition cards for the Agatha Discard deck

Aside from Agatha, who executes the overall strategy for this deck, the other win condition cards for this deck are:

  • Ghost Rider
  • Hela
  • Apocalypse
  • M.O.D.O.K.

Ghost Rider and Hela will be your critical cards since they can bring back the cards you discarded. As for Apocalypse, targeting it for the discard mechanic will increase its Power, potentially turning it into your most potent finisher.

M.O.D.OK. is your emergency card for the late game since it can discard all your cards simultaneously. This can further increase Apocalypse’s Power and boost one of your locations with an eight-Power card.

Agatha Harkness deck staple cards

Here are the staple cards you should play in an Agatha Harkness deck, along with their abilities:

  • Lady Sif: On Reveal: Discard the highest-cost card from your hand.
  • Blade: On Reveal: Discard a card from your hand.
  • Hela: On Reveal: Resurrect all cards you discarded from your hand to random locations.
  • Blue Marvel: Ongoing: Your other cards have +1 Power.

How to counter Agatha Harkness decks

Since you will automatically face a game AI if you encounter decks with Agatha, it is best to properly play your cards because the chances of the Agatha AI beating you are low—unless you either have an unlucky draw or just don’t know how to use your cards correctly.

The Agatha farm deck is more of a “throw anything, and it will work” deck. So, it is best to counter using cards that can destroy one-cost units, like Killmonger. Enchantress and Rogue, on the other hand, can disrupt the Ongoing effects of Ka-Zar and Blue Marvel. So, watch out for these cards. Or rather, Agatha should watch out for them.

Agatha Harkness decks’ current state in the meta

The Agatha farm deck is doing a pretty solid job in the current meta of Marvel Snap decks. Even if it may not be your first or second option on the ladder, its strategy where everything Agatha plays can work is decent. Also, it may be a solid choice in case you’re on a losing streak and want to rest while continuing the grind.

As for the Agatha Discard deck, it is a fun deck to play. Once you can discard Agatha, it turns into a full discard deck, which is almost always relevant in the meta. But if Agatha stays in your hand, it’s more about fun than competitiveness.
