This structure deck, released in 2016, brought upon the advent of new support for the Union archtype
Structure Deck: Seto Kaiba
Reading is fundamental, however, fail to read this Dinosaur XYZ and realize it's not once per turn on it's monster negate
Evolzar Dolkka
Lyrillsic Wagtail
Wind
This fake card is supposed to be a stand in for Exodia
Dark Master
This monster recently got a whole anime with her GF, even if the actual amount of time on screen was less than 10 minutes
Sky Striker - Raye
For the longest time, these level 4 machine monsters, were ran along aside the ABC's due to their easy access to rank 4's. Hope your opponent didn't have Effect Veiler on the normal.
Gold/Silver Gadget
If you read this card, you may fall asleep, however, it's defense position effect does stall out the game for at least two turns.
Number 41: Bagooska the Terribly Tired Tapir
Gold Pride - Leon
Wind
This Avian sure is apart of archetype of birds, one of which has it's link 3 banned.
Dark Simourgh
This newer archetype of monster, that also recently came to Master Duel, is all about those fours
Ryzeal
This archetype of monsters, was used with ABC's due to their spell cards, being able to dump ABC pieces to the GY
Ojama's
Sadly for this card, problem solving card text made this a nightmare to read through. No one would blame you if you misread it.
Snoww, Unlight of Dark World
Infernal Flame Banshee
Fire
This spell card was a corner stone in this discard heavy archetype, though it has seen almost as much play in Exodia FTK's
Dark World Dealings
This Spirit monster has been used for heinous things in flood gate decks, a wonder he himself hasn't been banned.
Amano-Iwato
This spell card, before it's banning and then subsequent errata, was a focal point into dumping easy material into the GY for setup plays.
Future Fusion
Better read this field spell carefully, otherwise that negation is happening at point of resolution, not activation.
Ryzeal Cross
Ghost Belle and Haunted Mansion
Earth
This iconic monster has gotten plenty of fusion support over the years, even if he is currently a skeleton in mementos
Dark Blade
This spellcaster has been pondering his grimoires and searching Invocation for almost a decade now.
Aleister the Invoker
This Fusion requires ABC and XYZ monsters in order to be made.
A-to-Z-Dragon Buster Cannon
I bet you didn't read Gagaga Cowboy, most know it deals 800 damage in defense, but in attack position it does this effect.
If this card attacks an opponent's monster this turn, it gains 1000 ATK, also the opponent's monster loses 500 ATK, during the Damage Step only.
Ryzeal Sword
Fire
This level 7 monster, was the first real "boss" monster of an archetype, even if said archetype was just... good stuff.
Dark Armed Dragon
This dragon really helped pull her entire archetype together, really tidied up the place.
Chamber Dragonmaid
