Here is an ABC deck built to perform against meta with some techs that increase it's stability, defensive abilities and OTK potential.
The basics like gadgets and Galaxy Soldier are still here to start the same loops that the classic builds.
So the specific cards you'll find are :
The Psy-Frame package, that is usefull to negate an Ash Blossom targetting a draw card or Terraforming/Union Hangar to have 2 monsters to start boards pretty effectively, or just use Psy-Frame Lambda's ability to negate cards during your opponent's turn to add disruption to your established board. Note that they are light attribute and are potential targets for Galaxy Soldier's effect.
The Sky Striker package is really good in this deck sinse it can search out multiple Sky Striker cards and cycle the deck when having good effects to handle the opponent's board. Kagari is a machine monster and can be used to summon Platinum Gadget. With Sky Striker Mecha - Shark Canon and Sky Striker Mecha - Widow Anchor you can handle annoying monsters in the graveyard or in the field like Plasma Destiny Hero, and steal opponent's monsters to rapidly gain access to Avramax and Borrelsword for OTK strategies.
Monster Gate can deblock hands by sending somme letters to the graveyard that would trigger summoning or searching effects and can bring out monsters like Silver Gadget or Gold Gadget to spam the board and gain access to ABC Dragon Buster even with a bricky hand. Note that you can send spells to the graveyard and instantly gain acces to the full power effects of the Sky Striker cards.
Twin Twisters are Added main deck to send a needed letter to the graveyard and break backrow cards and floodgates that could stop the deck in some situations.
The extra deck is quite generic, we Simply run a Gear Gigant X to search the last letters for the summoning of ABC Dragon Buster, and Crusadia Equimax to have a simple way to summon Mekk-Knight Crusadia Avramax with the Sky Striker combos or bypass the biggest beatsticks and potentially gain access to simple OTKs.
The side deck :
Dark Ruler No More is a great card against combo decks like Guardragons and won't be negated by Mystical Beasts monsters from Pendulum decks, it's also a spell card so it will allow us to triger the full power effect of Sky Striker cards more easilly.
Sky Striker Maneuver - Afterburners is an alternative way to handle monsters and is a safe way to break through monsters that prevent special summons like Vanity Fiend or monsters with annoying disruption effects to start our loops, it is searchable by Engage.
Fantastical Dragon Phantazmay is a good way to draw cards when going second against decks like Orcust, and can pressure opponent's play that set monsters with disruption effects
The artifact package is an excellent option to lock combo decks when going first with Artifact Scythe and can stop Orcust and Thunder Dragon with Artifact Lancea.
Lastly Anti-Spell Fragrance is a way to shut down Sky Striker and Pendulum when going first and won't be a problem after we set our board.
