 "'''Gem-Knight'''" (ジェムナイト ''Jemunaito'') is an [[archetype]] that was released in ''[[Duel Terminal - Vylon Descends!!]]''. They are used by [[Julia Krystal]] in the ''[[Yu-Gi-Oh! ARC-V]]'' anime. Their team symbol is a jewel droplet adorned with gold trim and two small, arced points. Its color varies according to the monster or object to which it is attached. All "Gem-KnightsKnight" monsters are [[EARTH]], whereas their [[Type]] varies between [[Pyro]], [[Thunder]], [[Aqua]], or [[Rock]] (with one , as well as a few [[Fairy]] as an exception), in keeping with the cardinal elements: fire, wind, water, and earth, respectively. "Gem-Knights" are further subdivided into trios: each Type includes a [[Normal Monster|Normal]] member, a [[Gemini monster|Gemini]] member, and a [[Fusion Monster|Fusion]] member. All members of this archetype are named after different minerals. Aesthetically, they appear to be a synthesis of [[Jesse Anderson]]'s "[[Crystal Beast]]s" and [[Jaden Yuki]]'s "[[Elemental HERO]]" cards, possibly as a an homage to their friendship in the anime. This is evidenced in cards such as "[[Gem-Knight Fusion]]", whose artwork is clearly a merging of "[[Crystal Release]]" and "[[Miracle Fusion]]". While the four In terms of playstyle, "Gem-Knight" Normal Monsters are shown to be unarmed, the ten monsters focus on rapidly and repeatedly Fusion Monsters wield weapons befitting Summoning their stats boss monsters by searching and effects (or lack thereof): "[[Gem-Knight Aquamarine]]" uses a bladed shield; "[[Gem-Knight Ruby]]" uses a polearm; "[[Gem-Knight Topaz]]" uses twin-bladed tonfa; "[[Gem-Knight Amethyst]]" carries a shield and what is either a wand or a slim blade; "[[Gem-Knight Citrine]]" uses a fire sword, and "[[Gem-Knight Prismaura]]" wields a lance recycling Fusion Spells and shieldMaterials. "[[Gem-Knight Zirconia]]," on the other hand, is equipped with gigantic fists seemingly to compensate for its lack of effectTheir core Fusion Spell, "[[Gem-Knight SeraphiniteFusion]]" uses a saber, and "can [[Gem-Knight Master Diamondreturn]]" uses a broadsword embedded with gems. "[[Gem-Knight Lady Lapis Lazuli]]", which deals effect damage, is depicted without any weapon."[[Gem-Knight Lady Brilliant Diamond]]" uses a simple sword. "Gem-Knight" is the first, and so far, itself from GY to the only archetype to boast six "[[Polymerizationhand]]"-styled cards: "Gem-Knight Fusion", "by [[Particle Fusionbanish]]", "[[Pyroxene Fusion]]", "[[Fragment Fusion]]", "[[Absorb Fusion]]", and "[[Brilliant Fusion]]". Regardless, "Gem Knights" are capable of rapidly Summoning Fusion Monsters with a mere "Gem-Knight Fusion" as its ability grants the user to repeatedly return itself to the owner's hand at the cost of banishing ing 1 "Gem-Knight" Monstermonster from GY, and with the assistance of "[[Gem-Knight Obsidian]]" and "[[Gem-Knight Lazuli]]" the user is allowed to can both recycle "Gem-Knight" Normal Monsters. Because of thisTheir team symbol is a jewel droplet adorned with gold trim and two small, arced points. Its color varies according to the player can Fusion Summon several times from their Extra Deck during the same turnmonster or object to which it is attached. ==StoryLore=={{Main|Duel Terminal Master Guide card storylines|Master Guide 5 card storylines|Master Duel card storylines#The Pyroxene Warriors}}

 "[[Dark-line Warrior CaingorgormCairngorgon, Antiluminescent Knight]]" appears to be a corrupted combination (probably by the "[[lswarm]]" virus) of "Gem-Knight Crystal", with parts of "Gem-Knight Zirconia" (right arm and left leg), "Gem-Knight Master Diamond" (left arm and right leg), and "Gem-Knight Prismaura" (damaged head).

The "Gem-Knight" Fusion Monsters each have their own effects, ranging from battle support, card destruction, to burn damage. They either require a specific "Gem-Knight" Normal Monster + any "Gem-Knight" monster as material, any "Gem-Knight" monster + any monster of a specific Type/Attribute as material, or 3 "Gem-Knight" monsters as materials.Each of the archetype's Fusion Spell/Traps have different effects and have different levels of importance:

 ==Playing style== The "Gem-Knight" employs rapid A key monster to the archetype's general strategy is their LINK 2 [[Fusion Summon|FusionLink Monster]] [[Beatdown]] strategy (similar to "[[Elemental HEROGem-Knight Phantom Quartz]]" monsters), accomplished with who is both a searcher for all archetypal cards, and also a Fusion Summoning extender able to Fusion Summon by shuffling materials in the GY or Banish Pile back into the use Deck.To quickly search out the archetype's five monsters for use as Fusion Spells/Traps and a wide array materials, the archetype can make use of recycling effectsarchetype-specific support (e.g. The : "[[Gem-KnightArmadillo]]" Normal Monsters benefit from most ), Normal Monster support cards, as well as (e.g.: "[[Gem-MerchantRescue Rabbit]]", whose effect resembles that of "[[Blackwing - Kalut the Moon ShadowUnexpected Dai]]"), or [[Rock]] support (e.g. "[[Gem-Knight AlexandriteAdamancipator Researcher]]" and , "[[Gem-ArmadilloBlock Dragon]]" provide excellent search power to facilitate this strategy). The archetype's key card is "[[Crystal Rose]]" is an indirect searcher that can copy the name of any "Gem-Knight Fusion]]", which, apart from granting access monster in Deck (allowing it to its vast arsenal of powerful Fusionsbe used as a Fusion or Link Material), can return itself to the hand at the price of and sends a "Gem-Knight" banished from the GraveyardDeck to GY, which can trigger floating effects. "[[DiscardCrystal Rose]] effects can come in handy: cards such as " and "[[Phoenix Wing Wind BlastBrilliant Rose]]" can remove threats from both have effects to Special Summon themselves and copy the fieldname of a "Gem-Knight" monster, while also loading providing indirect searching for specific Fusion Materials.To search out the Graveyard to pay this cost. archetype's Fusion Spells, external "Fusion" support cards like "[[D.D.R. - Different Dimension ReincarnationPredaplant Darlingtonia Cobra]]" and "[[Chaos ZonePredaplant Ophrys Scorpio]]" can re-Summon the be used, but "Gem-KnightsPhantom Quartz" banished via alone can be used to search out "[[Gem-Knight Fusion]]", essentially rendering the cost moot which can then be repeatedly used and restocking the hand with materials for another Fusion Summonreused. Since you can Fusion Summon Gem-Knights using other "[[Gem-Knight Fusion monsters, a Gem-Knight deck Quartz]]" can use search out the effects of Amethyst powerful "[[Brilliant Fusion]]" and Aquamarine "[[Scatter Fusion]]", but has heavy restrictions attached to eliminate troublesome Trap Cards and return monsters to the hand, making the field safer for cards like it.Two key "Gem-Knight Prismaura" monsters, "[[Gem-Knight Citrine, Obsidian]]" and Gem-Knight Ruby. Pairing "[[Gem-Knight Master DiamondLazuli]]" with , have non-once per turn effects that can recycle the player's monsters when sent to the GY, compensating for the costs of Fusion Summoning and extending the Field Spell player's Fusion plays. "[[Catapult ZoneGem-Knight Quartz]]" is also has a good tactic. As the GY recycle effect of "Master Diamond" allows it to gain 100 ATK with every "Gem-Knight" in the Graveyard, if it's prevented from getting destroyed by battle used as a Fusion Material, albeit being once -per -turn and send one Rockonly.===Gem-Type from Knight Beatdown===The intended strategy for the Deck to the Graveyard instead. By feeding in cards such as "Gem-Knight" archetype is likely a [[beatdown]]-focused one, focusing on Fusion Summoning multiple "Gem-Knight Lazuli]]"Fusion Monsters, ituse them to remove the opponent's ATK will steadily rise over 3000cards, which causes it to become less vulnerable and it can come in handy when dealing defeat the opponent with cards such as "the high ATK of the Fusion Monsters.===Gem-Knight FTK===This is an [[Hieratic Sun Dragon Overlord of HeliopolisFTK]]strategy focused on using the effect of ". The release of both [[Xyz MonsterGem-Knight Lady Lapis Lazuli]]s " and "[[Rescue RabbitGem-Knight Master Diamond]]" give (copying the effect of "Gem-KnightsLady Lapis Lazuli" another welcome boost) to repeatedly [[burn]] the opponent. "Rescue RabbitLady Lapis Lazuli" can bring out inflict 500 damage to the materials opponent for any each Special Summoned monster on the field. However, "Gem-KnightLapis Lazuli" Fusion Monsters (or even Xyz Summoning can only be Special Summoned once per turn, necessitating the use of "[[Gem-Knight Pearl]]Master Diamond"), and to copy the effect of "[[Lady Lapis Lazuli" and reuse its effects. Generally, Gem-Knight Amber]]FTK aims to swarm the player's own field with monsters and activate the effects of "Lady Lapis Lazuli" can return a banished once and "RabbitMaster Diamond" twice to inflict around 8000 damage to the hand for further usageopponent, achieving an FTK. === Recommended cards ==={{Decklist|Vanilla Style

===Weaknesses===Despite its speed and flexibility, "Gem-Knights" are not without weaknesses. Like the "[[Evil HERO]]" [[series]], which relies on "[[Dark Fusion]]" and "[[Dark Calling]]", the "Gem-Knights" depends upon their "[[Gem* Anti-Knight Fusion]]" for their usual repeated Fusion Summons (unless other Fusion Spell/Traps like "[[Pyroxene Fusion]]" also included). One of the most effective ways to cripple it is to activate a card like "[[Cursed Seal of the Forbidden Spell]]" or "[[Armageddon Designator]]" (the latter if your opponent also just so happens to be using "Gem-Knights" too)Special Summoning floodgates, which can render it unusable for the rest of the Duel. such as "[[Non-Fusion Area]]" can also damage its play-style, blocking all attempts at Fusion Summoning, leaving the Deck at a severe disadvantage (plus "[[Anti-Fusion Device]]" and "[[Steelswarm Sting]]" can expunge Fusions on the field). "[[Torrential Tribute]]" and "[[Needle CeilingArchlord Kristya]]", if activated at the right time, can also knock the "Gem-Knight" player off balance. Fortunately, "[[Seven Tools of the Bandit]]" or "[[Royal Decree]]" can be reliable answers for those threats but not for cards like "[[Dark HoleDimensional Barrier]]", "[[Lightning Vortex]]" or even "[[4-Starred Ladybug of Doom]]" (all non-Fusion "Gem-Knights" and some of their support are [[Level]] 4,) which will involve varying stratagems to counteract against (i.e. "[[Dark Bribe]]" and "[[Royal Command]]"). It is also for this reason that "[[Monarch]]" decks can easily defeat "Gem-Knights"; by locking down their Extra Deck with "[[Domain of the True Monarchs]]", "Gem-Knights" effectively lose, being robbed of their most powerful cardscan completely shut off the deck's game plan. A more typical concern would be anti* Anti-Special Summoning cards such as "[[Archlord Kristya]]", which are not as easily dealt with once on the field. Due to the [[Gemini Monster]] portion of the archetype, however, support Spell floodgates like "[[Gemini Spark]]" can be used to handle threats of this nature. The same applies for cards like "[[Macro CosmosNaturia Beast]]" or "[[Dimensional FissureImperial Order]]," so that they will not disrupt can prevent the stream of Fusions. Cards such as "[[Mist Wurm]]", "[[Byser Shock]]", "[[Guardian Sphinx]]" "[[Compulsory Evacuation Device]]", "[[Compulsory Escape Device]]" and "[[Neo-Spacian Grand Mole]]" can also get rid of your "Gem-Knights" Fusion Monsters (especially useful for dispatching deck from using "[[Gem-Knight AquamarineFusion]]" and "[[Gem-Knight Amethyst]]"). "[[Effect Veiler]]" or "[[Divine Wrath]]" are readily available responses. Occasionally, a "Gem-Knight" player's hand may clog up with Normal Monsters in a moment where "Gem-Knight Fusion" is nowhere to be found. This condition can be even worse if * GY floodgates like "[[Rescue RabbitMacro Cosmos]]" also included in the mix, since "Rabbit" can only Special Summon those Normal Monsters from prevent the Deck. "[[Gem-Turtle]]" can sometimes provide a remedy, as it retrieves a copy deck from the Deck and places it in the hand, but some players consider it dangerously slow in a fast-paced meta. Unfortunately, there is no guaranteed alternative available yet to solve this problem ("[[Pot of Duality]]" can be used, but not only will it suspend Fusion Summoning for a turn, but it also may not work as intended). Proper [[Deck Thinning]] cards can be used to increase the odds of drawing the correct cards; "[[Thunder Dragon]]" and "[[Volcanic Shell]]" are prime candidates for this role. If one or both are utilized, consider focusing the Deck around "[[Gem-Knight Prismaura]]" and "[[Gem-Knight Citrine]]," since "[[Thunder Dragon]]" and "[[Volcanic Shell]]" are [[Thunder]]-[[Type]] and [[Pyro]]-Type, listed as materials on the above-mentioned cards, respectively. Another strategy in this vein is using "[[Lavalval Chain]]" to put recovering "Gem-Knight Fusion" in the Graveyard. "[[Summoner Monk]]" can quickly put "Lavalval Chain" on the field at the cost of a Spell Card, but be warned: it is susceptible to cards such as "Effect Veiler", "[[Bottomless Trap Hole]]" and "[[Solemn Warning]]." * Most "Gem-Knight" Decks that utilize either decks use "[[Gem-Knight AlexandritePhantom Quartz]]" or "Rescue Rabbit" are also susceptible as their only way to "[[Mirror of Oaths]]", resulting a possibly loss of momentum. "[[Skill Drain]]" can also dangerous, since it will disable most in-field search "Gem-Knight" Fusion Monster's effect such as "Citrine", "Prismaura" or "[[Gem-Knight Seraphinite]]".  Cards like "[[Naturia Beast]]", "[[Naturia Exterio]]" and "[[Horus the Black Flame Dragon LV8]]" also pose a serious threat, since they can stop "Gem-Knight Fusion" from working no matter how many times making it is returned to the hand. Finally, "Gem-Knights" alone have no way of bouncing back into play once theydeck're [[banish]]ed, making "[[Macro]]" Decks a mismatch for thems main chokepoint. 

* This archetype appears to be based on the "[[Elemental HERO]]" archetype, since a few of their monsters' poses are based on the share similar stats (Level/ATK/DEF) and poses of the with some "Elemental HERO" monsters.<ref>{{cite web |url=http://www.pojo.biz/board/showthread.php?p=22284095#post22284095 |title=<nowiki>[Official Thread]</nowiki> Hidden Arsenal 4 : Special Edition post #120 |author=[[Kevin Tewart]] |date=July 21, 2011 (UTC) |publisher=Pojo.com Forums}}</ref><ref>{{cite web |url=http://www.pojo.biz/board/showthread.php?p=22284170#post22284170 |title=<nowiki>[Official Thread]</nowiki> Hidden Arsenal 4 : Special Edition post #125 123 |author=[[Kevin Tewart]] |date=July 21, 2011 (UTC) |publisher=Pojo.com Forums}}</ref><ref>{{cite web |url=http://www.pojo.biz/board/showthread.php?p=22284193#post22284193 |title=<nowiki>[Official Thread]</nowiki> Hidden Arsenal 4 : Special Edition post #125 |author=[[Kevin Tewart]] |date=July 21, 2011 (UTC) |publisher=Pojo.com Forums}}</ref>** "Gem-Knight" monsters are all of one Attribute ([[EARTH]]), yet have a variety of Types, whereas the anime-based "Elemental HERO" monsters are all of one Type ([[Warrior]]), but of different Attributes.* In context of the "gem" theme, this archetype also appears to be based on the "[[Crystal Beast]]" archetype, since [[Jaden Yuki]] and [[Jesse Anderson]] were friends in the [[Yu-Gi-Oh!
