Zarc (ズァーク Zāku) or Z-Arc is a character in Yu-Gi-Oh! ARC-V anime and the true main antagonist of the series. Before his revelation, he is known as The Darkness or Black Shadow residing inside Yūya Sakaki and his dimensional counterparts. He is the original incarnation of Yūya Sakaki (Standard Dimension), Yūto (Xyz Dimension), Yūgo (Synchro Dimension), and Yūri (Fusion Dimension). Zarc's growing aggression led him to destroy the Original Dimension and take on a dragon form known as Supreme King Dragon Zarc. During his confrontation with Ray, Zarc's soul was split into four and reincarnated into four different lives. He is the original owner of the Four Heavenly Dragons and one of true co-creators of Pendulum Summon.
The Supreme King Deck in the anime doesn't have a really articulated play style by itself given its small membership but can work effectively as an engine. Using "Supreme King Dragon Darkwurm", the player is capable of toolboxing into the "Supreme King Gates", the archetype's main sources of a Pendulum Scale. Since both "Supreme King Gate Zero" and "Supreme King Gate Infinity" have Scale values of 0 and 13 respectively, they can potentially allow for monsters of any Level to be Pendulum Summoned, although "Infinity" carries a restriction of controlling no monsters in order to Pendulum Summon. So far, there is only one Ritual monster in the archetype, Demise, Supreme King of Armageddon which specializes in the destruction of every card on the field, inflicting 200 points of damage for each card destroyed that way.
Since they cannot do enough on their own given they have few members, the archetype is thus better mixed with other Pendulum cards to maximize the benefits. The "Supreme King" archetype pairs extremely well with the "Magician" archetype, especially "Z-ARC Magician" monsters.
For starters, most of them are DARK monsters so they cannot conflict with the Pendulum Effect of "Darkwurm". Secondly their Pendulum Scales have values of 1 and 8, which mix well with the "Supreme King" cards since "Darkwurm" is Level 4 and both "Gates" are Level 7. Thirdly these "Magicians" along with "Chronograph Sorcerer" are one of the ways to Special Summon "Supreme King Z-ARC", the archetype's boss monster. Additionally, the effect of "Darkwurm" to Special Summon itself from the Graveyard makes it a useful discard fodder for cards such as "Pendulum Call" as the player can instantly gather the means for a Pendulum Summon for no cost and their Pendulum Scales will go uninterrupted.
As a result of this mixture the "Supreme King" archetype is capable of more moves, involving greater flexibility in both Pendulum Summon and other Summon mechanics, being able to perform Fusion, Synchro and Xyz Summon.
For Fusions, both "Zero" and "Infinity" can provide some help since "Zero" can destroy itself along with "Infinity" to search for any "Fusion" card that can help conduct a Fusion Summon, some useful choices including "Miracle Synchro Fusion" and "Odd-Eyes Fusion". Given the Deck's mostly DARK nature, they can also Fusion Summon "Starving Venom Fusion Dragon" (and most other "Predaplant" Fusion monsters, and "Greedy Venom Fusion Dragon", if need be).
For Synchro Summoning purposes, "White Wing Magician" being a Level 4 can open possibilities for either Level 7, 8, or even Level 11 Synchro Summoning when paired with either a Level 3, 4, or 7. Since unlike other Tuner Pendulum Monsters, she has no restriction on what she can Summon (but using her after being Pendulum Summoned will banish her), she is an ideal Tuner for generic Synchro Monsters such as "Red Dragon Archfiend", "PSY-Framelord Omega" or "Enlightenment Paladin". If needed other monsters can be used too, such as "Ghost Ogre & Snow Rabbit", "Timebreaker Magician" or "Noble Dragon Magician" can open up room for Level 7 Synchro Summoning such as "Clear Wing Synchro Dragon" or "Black Rose Dragon". Some of these cards can combo well with "Miracle Synchro Fusion" as well.
Finally, for Xyz Summoning, the archetype can gain easier access to either Rank 4 or Rank 7 monsters, ranging from utilitarian ones such as "Dark Rebellion Xyz Dragon", "Number 39: Utopia", "Number 104: Masquerade" or "Timestar Magician" to the likes of "Number 11: Big Eye" or "Odd-Eyes Absolute Dragon". "Darkwurm" is interesting due to its self-revival ability from the Graveyard which potentially mitigates some of the otherwise common and taxing cost of Pendulum-Xyz tactics. "Number 39: Utopia" can negate attacks to prevent your weaker monsters and this card from getting destroyed, while "Number 104: Masquerade" can be useful since its first effect sends one card on your opponent's deck to the Graveyard and its other effect can negate an opponent's monster effect and inflict damage to your opponent.
After dumping "White Wing Magician", "Black Fang Magician", "Purple Poison Magician", by detaching them and sending a "Pendulum Dragon" to the Graveyard by "Foolish Burial", they can then be banished for "Z-ARC".
For Pendulum Summoning, other additional and more mainstreamed cards such as "Odd-Eyes Pendulum Dragon", "Archfiend Eccentrick" or "Odd-Eyes Arc Pendulum Dragon". The former can search either of the "Gates" and many of the aforementioned "Magicians", while "Eccentrick" is an effective removal card. In other words, the "Supreme King" archetype is fairly flexible since they can be mixed with multiple cards and provide a handful of utilitarian uses.
As per the Master Rule 4, the deck loses its Pendulum Summon power. However, the player would often stand without Pendulum Summon as per the Pendulum Effect of "Infinity" thanks to the archetype's penchant for swarming and controlling the field through its "boss".
After swarming the Field with weaker monsters, the player can bring out "Supreme King Dragon" Extra Deck Monsters and use them to press the opponent. After your opponent gets rid of them and you managed to get "Z-ARC" on the field, you can use "Supreme Rage" to devastate, or even finish the opponent.
