The July 19 patch has upended the Marvel Snap metagame. Many of the most potent archetypes are significantly weaker, or in some cases no longer functional. Others are dependent on a large number of Pool 3 components which limits their accessibility. Collector Swarm is a fun, skill-testing deck with an impressive power level that remains easy to build, easy to tweak, and highly competitive in the post-patch world.
What is Collector Swarm?
Collector Swarm is a highly synergistic combo deck that leverages the power of discard effects in a way that allows it to assemble both tall and wide boards. It is a versatile archetype with a number of different build options, including little reliance on any specific Pool 3 cards. The deck can focus on its primary plan, tweaking it along the axis of explosiveness versus consistency, but it can also run some potent disruptive tools without significantly compromising its power.
The game plan with Collector Swarm is to deploy multiple cards that discard cards from your hand on reveal, enjoying the fact that these cards are above-rate on power level while also turning their drawback into an upside. The deck does this through cards like Swarm and Apocalypse that actively want to be discarded, as well as through cards like Morbius and The Collector which scale from these effects. It closes out games with a combination of multiplied Swarms and large bodies, producing very high amounts of total power without fully committing to lanes too early in the game.
This list includes four discard outlets: Blade BladeOn Reveal: Discard a card from your hand., Lady Sif

ApocalypseWhen you discard this from your hand, put it back with +4 Power.. This, combined with the potential inclusion of Moon Girl

The CollectorWhen a card enters your hand from anywhere (except your deck), +2 Power., very easily scaling him into the double digits. Dracula
DraculaAfter the final turn, discard a card from your hand. This has its Power. fits well with this package, freeing up mana on turn 6 to empty the hand after a Moon Girl

Build Options
The above list contains three cards from Pool 3. This may seem intimidating, but in fact, none of them are mandatory inclusions. Collector Swarm is a deck that is very friendly to improvisation around available cards.
Discard Outlets
As with most any deck that includes discarding synergies, Blade BladeOn Reveal: Discard a card from your hand. and Lady Sif
Lady SifOn Reveal: Discard the highest-cost card from your hand. are easy inclusions. They are cheap, have good energy-to-power ratios, and play an important role in sculpting hands. Lady Sif
Lady SifOn Reveal: Discard the highest-cost card from your hand.’s ability to control the target of the discard is also essential for setting up the late game. Unlike with some Swarm Zoo or Ghost Rider decks however, the large number of synergies in Collector Swarm demand some additional discard outlets.
Colleen WingOn Reveal: Discard the lowest-cost card from your hand.
Colleen Wing Colleen WingOn Reveal: Discard the lowest-cost card from your hand. is one strong option. Like Lady Sif
Lady SifOn Reveal: Discard the highest-cost card from your hand., she can target specific cards, often delivering the initial discard of Swarm
SwarmWhen this is discarded from your hand, add two 0-Cost copies to your hand.. She can also help to clear the hand for Apocalypse in order to set up Dracula
DraculaAfter the final turn, discard a card from your hand. This has its Power. since she will never hit Apocalypse
ApocalypseWhen you discard this from your hand, put it back with +4 Power. unless he is the only remaining card. Her 3|5 body is also a good rate, allowing the deck to threaten the lane where it deploys her.
Moon KnightOn Reveal: Discard a card from each player's hand.
Moon Knight Moon KnightOn Reveal: Discard a card from each player's hand. offers disruption in exchange for a smaller body. The impact of this disruption will vary, but in some cases, it can be back-breaking. Some decks rely heavily on specific components, and Moon Knight
Moon KnightOn Reveal: Discard a card from each player's hand. will occasionally trigger instant retreats. As a discard outlet, however, his single random discard is the worst effect available, the same as Blade
BladeOn Reveal: Discard a card from your hand.. Combined with his weak body and the inconsistency of his disruption, he will sometimes feel awkward. He is also weak in the mirror since he can sometimes help your opponent, so he will become less attractive if Collector Swarm becomes more popular.
GambitOn Reveal: Discard a card from your hand. Destroy a random enemy card.
Gambit GambitOn Reveal: Discard a card from your hand. Destroy a random enemy card. is an even more extreme version of Moon Knight
Moon KnightOn Reveal: Discard a card from each player's hand.. Like Moon Knight
Moon KnightOn Reveal: Discard a card from each player's hand., he has a single random discard and can sometimes have a very little disruptive impact. His body is even worse than Moon Knight
Moon KnightOn Reveal: Discard a card from each player's hand.’s, an abysmal 3|1. His ability to disrupt the opponent’s board and erase energy that they have already committed has extreme high roll potential. Gambit
GambitOn Reveal: Discard a card from your hand. Destroy a random enemy card. is the discard option furthest away from facilitating a consistent combo strategy and toward disruption and unpredictability.
HellcowOn Reveal: Discard 2 cards from your hand.
Hellcow HellcowOn Reveal: Discard 2 cards from your hand. is the opposite of Gambit
GambitOn Reveal: Discard a card from your hand. Destroy a random enemy card.. It is the most explosive, as the only card that discards two cards at once. It also has an enormous 2|6 body which will even match Morbius
MorbiusOngoing: +2 Power for each card you discarded from your hand this game. on the rate in some games. It is very good at clearing the hand for Dracula
DraculaAfter the final turn, discard a card from your hand. This has its Power., can trigger Swarm
SwarmWhen this is discarded from your hand, add two 0-Cost copies to your hand. and Apocalypse
ApocalypseWhen you discard this from your hand, put it back with +4 Power. multiple times, and is so cheap that it presents no challenge to play two copies after Moon Girl
Moon GirlOn Reveal: Duplicate your hand.. There will sometimes be situations in which the two discards make it awkward or risky to deploy, but it tends to make up for this with its power. Hellcow
HellcowOn Reveal: Discard 2 cards from your hand. is especially attractive in builds that want to run only three discard outlets.
Sword MasterOn Reveal: Discard a card from your hand.
Sword Master Sword MasterOn Reveal: Discard a card from your hand. is also a card that merits a mention. Compared to the Pool 3 options, 4 mana is too expensive for a single random discard with no additional upside. The rate of 4|7 is good, but this does not make up for the high cost. The one place where Sword Master
Sword MasterOn Reveal: Discard a card from your hand. is worth considering is in a “budget” version of the deck for players who have not pulled any of the Pool 3 discard outlets. A build running only Blade
BladeOn Reveal: Discard a card from your hand., Lady Sif
Lady SifOn Reveal: Discard the highest-cost card from your hand., and Sword Master
Sword MasterOn Reveal: Discard a card from your hand. will be functional, albeit noticeably worse.
DraculaAfter the final turn, discard a card from your hand. This has its Power.
Dracula DraculaAfter the final turn, discard a card from your hand. This has its Power. is a potent option in Collector Swarm. The deck wants to deploy Apocalypse
ApocalypseWhen you discard this from your hand, put it back with +4 Power. in almost every game where it draws him, but this ties up turn 6 entirely and is extremely predictable. Dracula
DraculaAfter the final turn, discard a card from your hand. This has its Power. allows an earlier play which will free up turn 6 and allow you to conceal more information. It is also more powerful than playing Apocalypse
ApocalypseWhen you discard this from your hand, put it back with +4 Power. on his own, both because it discounts him by 2 mana and because Dracula
DraculaAfter the final turn, discard a card from your hand. This has its Power. himself is a discard outlet. Discarding Apocalypse
ApocalypseWhen you discard this from your hand, put it back with +4 Power. at the end of the game will give Morbius
MorbiusOngoing: +2 Power for each card you discarded from your hand this game. and The Collector
The CollectorWhen a card enters your hand from anywhere (except your deck), +2 Power. an additional +2 power while also giving Apocalypse
ApocalypseWhen you discard this from your hand, put it back with +4 Power. himself an additional +4, which is added to the power Dracula
DraculaAfter the final turn, discard a card from your hand. This has its Power. gains. The primary drawback of Dracula
DraculaAfter the final turn, discard a card from your hand. This has its Power. is that he costs 4 mana and does not contribute to the game plan during the game itself, which can feel clunky. He also relies on Apocalypse
ApocalypseWhen you discard this from your hand, put it back with +4 Power. for his maximum power, although it is sometimes acceptable for him to discard something smaller. Note that opponents will often play around Dracula
DraculaAfter the final turn, discard a card from your hand. This has its Power. as if he has 20 power, so he can be used to claim a lane and even to bluff.
WongOngoing: Your On Reveal abilities at this location happen twice.
Wong WongOngoing: Your On Reveal abilities at this location happen twice. is often seen as an alternative to Dracula
DraculaAfter the final turn, discard a card from your hand. This has its Power.. This is primarily because, like Dracula

SwarmWhen this is discarded from your hand, add two 0-Cost copies to your hand.s that Wong
WongOngoing: Your On Reveal abilities at this location happen twice. will often generate. Perhaps most importantly, she adds to the deck’s overall consistency by allowing it to draw from an 11-card pool for the first 5 turns and by making the final draw predictable. Due to the nuances of managing board slots and cards in hand, this deck benefits particularly strongly from this effect. Chavez’s nerf to 9 power in the July 19 patch does not significantly impact her role in Collector Swarm.
Moon GirlOn Reveal: Duplicate your hand.
Moon Girl Moon GirlOn Reveal: Duplicate your hand. is an obvious consideration in any deck running The Collector
The CollectorWhen a card enters your hand from anywhere (except your deck), +2 Power.. Her ability to add 10 power to the board for 4 mana can be very potent. Because Collector Swarm does not always include her, she can be more surprising than she would be in a more traditional Collector deck with cards like Devil Dinosaur
Devil DinosaurOngoing: +2 Power for each card in your hand.. There will be games where she makes it difficult for the deck to empty its hand for Dracula
DraculaAfter the final turn, discard a card from your hand. This has its Power., but multiplying discard outlets will often mitigate that. Moon Girl
Moon GirlOn Reveal: Duplicate your hand. is, as always, a card with a high skill ceiling. Her high cost and tendency to sometimes clog the hand make her a less consistent but more explosive option.
OkoyeOn Reveal: Give every card in your deck +2 Power.
Okoye OkoyeOn Reveal: Give every card in your deck +2 Power. was a staple in Collector Swarm before her nerf in the July 19 patch. Costing 2 mana makes her much more difficult to throw away later in the game or sneak into the mana curve earlier. As such, most lists have cut her. However, Swarm
SwarmWhen this is discarded from your hand, add two 0-Cost copies to your hand. multiplies buffs, and Okoye
OkoyeOn Reveal: Give every card in your deck +2 Power. is the main card besides Nakia
NakiaOn Reveal: Give all cards in your hand +2 Power. that can reasonably seed a buff onto it. It would not be outrageous to include Okoye
OkoyeOn Reveal: Give every card in your deck +2 Power., particularly for players who lack Pool 3 cards they might otherwise run. It is worth noting that the 2-slot on the deck is already fairly crowded, so Okoye
OkoyeOn Reveal: Give every card in your deck +2 Power. will compete with other cards on the curve.
Tech Cards
It is possible to make room in the deck for a tech slot. The best option is probably Killmonger KillmongerOn Reveal: Destroy ALL 1-Cost cards. since Collector Swarm does not rely significantly on 1-drops. Losing a Blade
BladeOn Reveal: Discard a card from your hand. is generally acceptable, and sometimes it will be possible to play Blade
BladeOn Reveal: Discard a card from your hand. after Killmonger
KillmongerOn Reveal: Destroy ALL 1-Cost cards.. Builds with Killmonger
KillmongerOn Reveal: Destroy ALL 1-Cost cards. would want to consider cutting some other 1-drops such as Sunspot
SunspotAt the end of each turn, gain +1 Power for each unspent Energy. or Nightcrawler
NightcrawlerYou can move this once.. Another tech option would be Armor
ArmorOngoing: Cards at this location can't be destroyed., since decks with destroy synergies did fairly well in the July 19 patch. Shang-Chi
Shang-ChiOn Reveal: Destroy all enemy cards at this location that have 9 or more Power. would also be worth considering, depending on how the meta shakes out. When in doubt, it is generally better to stick to a more proactive build.
Conclusion
Collector Swarm was a powerful option before the July 19 patch. As one of the top archetypes least affected by the nerfs, it is very well situated in the current meta. It is a somewhat complicated deck with a bit of a learning curve, but it is rewarding and fun to play.

Strong GuyOngoing: If your hand is empty, +6 Power., this is one of the best options available. It is also far less reliant on specific Pool 3 pulls than many other archetypes. Please reach out to me on Discord at Scrub#2573 if you try it out!
