While I wouldn’t describe this as a competitive deck, it can’t be denied that, ever since Kinetic Soldier and Spikeshield with Chain were introduced into the game, players have to think about it twice before blindly attacking into a face-down monster. If you haven’t tried out this deck yet, this is probably the best time to do so, given how popular Masked HEROes are in the current KC Cup.
Kinetic Soldier and Spikeshield with Chain give you a rather quick and unexpected win condition that is sure to leave your opponent speechless.
During Damage Calculation, if Kinetic Soldier is battling a Warrior-Type monster, it gains 2000 ATK and DEF, reaching 3350 ATK and 3800 DEF. You can rely on the overwhelming popularity of Masked HERO decks or you can use DNA Surgery to turn all monsters on the field into Warrior-Type monsters and get to those massive numbers consistently.
Spikeshield with Chain can be activated during the Damage Step and equipped to your own monster, it will increase the ATK of that monster by 500 and, if your opponent attacks while it’s in Defense Position, it will also make it gain DEF equal to its ATK during damage calculation only. If Kinetic Soldier is attacked by a Warrior-Type monster while in Defense Position and you activate Spikeshield with Chain targeting it, its DEF will reach 7650, which is usually going to be more than enough to end the game.
Amazoness Swords Woman is a great card in the current meta, it reduces the chances of an OTK thanks to its effect and it can deal substantial damage to the opponent by attacking into high ATK monsters such as Blue-Eyes White Dragon and Cosmo Brain.
You can attack an opponent’s Defense Position monster with Amazoness Swords Woman and then target that monster with Spikeshield with Chain, similarly to how Massivemorph was used before it was Limited to one copy per deck.
These Trap Cards are arbitrary and easily interchangeable with any other form of protection. The main cards of the deck are the ones listed in the “Essential Cards” section: if you don’t have Drowning Mirror Force or Paleozoic Canadia, you can still build this deck starting from Kinetic Soldier and DNA Surgery.
Cosmic Cyclone, Galaxy Cyclone and Hey, Trunade! are very common cards in Masked HERO decks, they are used to quickly get rid of the opponent's backrow and enable OTKs, but Sphere Kuriboh does not care about them;
Sphere Kuriboh can prevent an opponent's monster from attacking by switching it into Defense Position. If there is no imminent threat, turn off your Toggle Button when your opponent attacks, it will induce them to make more risky plays and use all of their resources at once to end the game.
Drowning Mirror Force is extremely destructive when it goes off and, while it's true that its activation requirements are a bit strict, it's the perfect card to face off against Masked HEROes, as it punishes the opponent for trying to go around your face-down monsters and attacking you directly.
Blue-Eyes has a really hard time coming back from this card in particular as it doesn't send the monsters on the field to the Graveyard, it just shuffles them back into the Deck.
Endless Trap Hell replenishes your resources while also preventing you from decking out before the opponent. Most games are decided quickly, but this is still the best Skill to run with most backrow-heavy decks.
A pretty obvious choice, Parasite Infestation can cause your opponent to lose 1000-2000 Life Points while also giving them a dead draw and clogging their Monster Card Zones.
