So, one would normally think that an archetype like the Twins wouldn't work in a format with a Summon Limit, like Trinity. Well, that's only how it appears on first glance. The Live☆Twins provide an easy shell to give the deck a solid turn 1 play in the form of either of their Links, or a Rank 2 Xyz monster. To follow this up, various backrow is necessary to allow the deck to try and establish their loop involving both of the Evil★Twins, with cards like World Legacy Awakens, World Legacy Clash, Evil★Twin Challenge, and Mirror Force.
To fill the void in which things don't go according to plan, the deck is filled with a number of standalone monsters that can easily provide pressure until you can get the Twins going, sometimes even being able to just win on their own. Danger provides bonuses from being discarded by cards like the Knightmares, Paleozoic Dinomischus, and Live☆Twin Home, as well as being able to summon themselves from hand in a pinch. Dogmatika, on the other hand, provides solid value and beaters in the form of Dogmatika Fleurdelis and Dogmatika Theo, with Dogmatika Ecclesia being able to search both of them, with Albaz allowing you to punish DARK and high ATK decks, as well as activating the Danger effects by discarding them. After that, you get into singleton value cards like Ancient Warriors - Loyal Guan Yun serving as a beater and situational removal, Lady Debug allowing you to search monsters in a pinch, and Gussari @Ignister allowing you to punish your opponent for attacking over your Link monsters.
If you do get to looping the Evil★Twins, you're given access to rather solid wincons. The unique property of the Twins reviving the other as a quick-effect allows you to repeatedly send them to the GY via Tribute effects or Link materials to revive them and gain their on-summon effects. By doing this repeatedly, you can gain strong value off of the Knightmare monsters, which provide buffs and draws when co-linked and have a floodgate in the form of Knightmare Gryphon that can effectively stop your opponent in their tracks, while you can use cards like Zero-Day Blaster, Dark Factory of More Production and Cynet Regression to take advantage of the recursive quick revival.
In terms of value the prior cards are all very effective, but sometimes you just need a little bit more, which is why I have my own special techs to help bridge that gap. First on the list is Number 29: Mannequin Cat. Her effect allows you to punish a deck that Special Summons against you. Granted, you don't have targets for every Attribute, but you have them for the 2 most common Attributes, Light and Dark. Unfortunately, you don't always get to set up defensive plays, which is where Formud Skipper comes into play. By using his effects, you can Link for Appliancer Laundry Dragon, who can crash into an opponent's monster, destroy and burn your opponent for that monster's ATK, and then summon Gussary @Ignister from your hand due to its effect that searches it when its Linked off. Lastly, is my Rank 4 Xyz monster of choice in Light Dragon @Ignister. While Exciton may be a better card in terms of boardbreaking and comeback factory, Tornado Dragon to answer backrow, or even Castel/101 to deal with indestructible monsters, Light Dragon provides your monsters with protection from destruction via card effect, has non-targeting removal, but most importantly can be used with other Cyberse monsters to revive your Link monsters, along with the added bonus of being able to summon back Linguriboh by Tributing itself.
The side deck is much simpler to explain, as its just as it seems. A number of backrow removal Spells in their to try and make the matchup vs backrow/control decks not quite so painful along with Linkslayer, Kongreat and D.D. Crow to deal with GY focused decks or decks that send from deck/hand to GY like Rituals, Victoria and Electric Virus for the matchup vs Dragon decks like Dragonmaids, The Chaos Creator & Chaos Space is try and not just lose to 1 of your Evil★Twins being banished, Chain Disappearance is specifically to banish 3 copies of Chamber Dragonmaid, Brain Control is to give a bit of solid "removal" vs decks that have strong maindeck monsters, and Degrade Buster is to face down high ATK decks.
And that about sums up the deck. If you can establish the Evil★Twin loops, the deck can snowball quite well. Even if it can't you can always fall back onto simple beatdown gameplay. If people want an in-depth guide regarding gameplay for the deck, I'll provide that in the future, but 'tis all for now.
