Deck Strengths
  • The deck's core is one of the strongest control elements in the game. Cocoon/BSG are fantastic for stalling, Mask + Paracide clog up your opponent's field so they're unable to mount an attack, and Lava Golem punishes your opponent if they try to set their monsters and stall. 
  • Weevil easily deals with slow decks that can't swarm rapidly or have low attack power. Residual damage from Paracides, Masks, and Lava Golem adds up over time against decks that cannot power through Weevil's backrow. 
  • Has a good matchup against Last Gamble and Luck on Your Side, as they rely on lowering their own LP. Parasite burn excels in doing minor amounts of damage to win the game.  
Deck Weaknesses
  • The Parasite Infestation skill partially relies on luck, it can shuffle anywhere between 1 and 2 Paracides into your opponent's deck. This makes Jade Insect Whistle a liability, if you draw more Whistles than Paracides in your opponent's deck, the extra copies are almost always useless. 
  • Struggles against faster decks that can push through their defenses. E.g. Red-Eyes, if they open well, can bulldoze through Weevil if the Weevil player can't halt their momentum. 
  • Decks that can get rid of Masks are troublesome. Gravekeepers or Red-Eyes can tribute off Masks/Paracides and make very aggressive plays, making them one of Weevil's worst matchups. Other decks like Phoenix can remove Masks and clear backrow, making them a pain to deal with. 
Deck Summary

One of the slowest decks on the ladder, Parasite burn is something that most players dread seeing. The deck works by using Mask of the Accursed, Burning Land, and Parasite Paracide to whittle down your life points while preventing you from attacking. It's a very simple strategy, but many decks have difficulty dealing with Mask and stall cards like Cocoon of Evolution and Big Shield Gardna.

Core Cards
Card Explanation

While you shouldn't be running Paracide in your deck, your opponent will hopefully find a few Paracides in theirs. This is the linchpin of the deck, your opponent drawing Paracide is a huge boon for the Weevil player, as Paracide does 1000 damage, provides a weak 300 DEF monster to attack with Panda, and removes field spell benefits.

It's worth noting that if your opponent's field is filled, Paracide won't be summoned if they draw it. 

Run 0, but hope that Infestation gives your opponent 3.

Cocoon is used for exactly one purpose, and that's to stall with a solid 2000 DEF. It's 0 ATK leaves it vulnerable to being changed into attack position with Enemy Controller, but the 2000 DEF is high enough to be naturally above most 4-star monsters. Your opponent will often be forced to summon a 5-star monster to get over Cocoon, buying you valuable time.

Run 1-3x, if you don't have Gardna run 3x.

Big Shield Gardna

Gardna is very similar to Cocoon, but it has a higher defense with a greater risk for being punished. Running high numbers of attack blockers and Masks mitigate Gardna's weaknesses extremely well, and the extra defense is crucial in this metagame to stand up to strong threats like Naturia and Red-Eyes.

Run 1-3x, a combined 3-4 stall monsters.

Lava Golem

A recent new addition, Lava Golem is a great help to Weevil strategies. The ability to remove two threats at once and inflict 1000 damage per turn is a godsend against new decks that can swarm rapidly. Slapping a Mask on a freshly summoned Lava Golem removes two monsters and deals 1500 damage per turn, which puts your opponent on a very short clock to win. His high 3000 ATK comes with a cost though, it is highly recommended that Lava Golem be played with 3x Mask of the Accursed and possibly Kotetsu to reliably stop Lava Golem from backfiring. 

Run the 1 copy in the game and 1-3x Doomdog Octhros to search it.

Jade Insect Whistle

A very important card for Weevil to ensure that your opponent draws Paracide. As mentioned above, since Infestation randomly shuffles between 1-2 Paracides, running 2x Whistle can cause issues if Infestation doesn't shuffle in enough Paracides, but Whistle is so good that it's worth running a few copies. One of the best parts of Whistle is that it forces your opponent to draw something useless instead of a possible counter card. 

Run 1-2x

Mask of the Accursed

Another part of the deck's core, Mask is essential to lock down your opponent and burn for 500 every turn. Running Mask is fairly self explanatory; be wary of using Mask on normal monsters, since your opponent may have Order to Charge ready to remove it.

Run 3x minimum

One of the newer cards in Paracide burn, Burning Land really helps Weevil outlast the opponent. The continuous chip damage as well as removal of field spells like Harpie's Hunting Ground is essential, paired up with Mask and Panda it ensures that your opponent will run out of life points before you do.

Play Burning Land carefully, if your opponent can sneak an attack in and reduce your life points below theirs, Burning Land can bite you in the rear.

Run 2-3x

Replacement/Tech Cards
Card Explanation

Another option for stall, Cobra Jar can sponge two attacks and inflict 500 damage to your opponent, which is a pretty solid deal.

Much like Skystarray, Inaba is used to poke your opponent for small amounts of damage every turn. Skystarray is generally superior since Inaba forces you to continue to re-summon it, while you can still set other monsters with Skystarray out.

While Pumprincess has the unfortunate side effect of clogging up your spell/trap zones, Pumprincess' utility is not to be underestimated. If she isn't dealt with, Pump is almost a win condition as she will steadily reduce the attack of your opponent's monsters and force out their spell removal. A strong card to help stall and allow Panda to do more damage.

Enemy Controller

While not included in the main deck, Enemy Controller vs Sphere Kuriboh is a nuanced choice. Sphere Kuriboh has the advantage of being in your hand to avoid spell/trap removal and keeping your spell/trap zones open for Burning Lands/Masks. Enemy Controller is very helpful in the Weevil mirror match in order to tribute away Masks and occasionally allow Panda to attack, but it risks being vulnerable to spell/trap removal.

Run 1-3x Enemy Controller or Security Orb to replace Sphere Kuriboh

This card isn't very good on the ladder because it's only useful versus very specific decks, but tribute summon decks are a big threat for Weevil. If you're expecting to play against Gravekeeper's or tribute decks, Blast can be a blowout card.
