 I ACTIVATE SIDA, spelled "'''"Gemknight"Gem-Knight''' " (ジェムナイト ''Jemunaito'') in Japan, is an [[archetype]] that was released in ''[[Duel Terminal - Vylon Descends!!]]''. Their team symbol is a jewel droplet adorned with gold trim and two small, arced points. Its color varies according to They are used by [[Julia Krystal]] in the monster or object to which it is attached''[[Yu-Gi-Oh! ARC-V]]'' anime. All "Gem-Knights Knight" monsters are [[EARTH]] [[Attribute]], whereas their [[Type]] varies between [[Pyro]], [[Thunder]], [[Aqua]], or [[Rock]]-, as well as a few [[TypeFairy]] (with one Fairy 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. They All members of this archetype are all 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]]".In terms of playstyle, " While the three Gem-Knight [[Normal Monster]]s are shown to be unarmed, the nine [[" monsters focus on rapidly and repeatedly Fusion Monster]]s wield weapons befitting Summoning their stats boss monsters by searching and recycling Fusion Spells and effects (or lack thereof): Materials.

"[[Gem-Knight ZirconiaLazuli]]," on the other hand, is equipped with gigantic fists seemingly to compensate for its lack of effect, can both recycle "[[Gem-Knight Seraphi]]" uses a saber, and "[[Gem-Knight Master Dia]]" uses a broadsword embedded with gemsNormal Monsters. "Gem-Knight" Their team symbol is the first, a jewel droplet adorned with gold trim and so fartwo small, arced points. Its color varies according to the only archetype monster or object to boast four "[[Polymerization]]"-styled cards: "[[Gem-Knight Fusion]]," "[[Particle Fusion]]," "[[Pyroxene Fusion]]," and "[[Fragment Fusion]]." This allows "Gem-Knight" to perform Fusions with far greater speed and efficiency than any comparable archetype, given that "[[Pyroxene Fusion]]" and "[[Fragment Fusion]]" in particular are [[Trap Card]]swhich it is attached. ==StoryLore=={{Main|Duel Terminal Master Guide card storylines|Master Guide 5 card storylines|Master Duel card storylines#The Pyroxene Warriors}}A group of warriors endowed with the power of minerals, the "Gem-Knights" value honor above all else and disapprove of battle for the sake of battle. At the provocation of the barbaric "[[Laval]]"," however, they are forced to take up arms and protect the clans from their wanton destruction. However, the "[[Steelswarm]]" begin to invade the surface land, intending to take over. The Gem-Knights join up with the other clans in a temporary union spearheaded by the "[[Vylon]]s"." Along the way, they obtain [[Gem-Knight Prismaura|new powers]] with which to resist the "Steelswarm"." Although the "[[Steelswarm]]" are quickly dispatched, conflict is far from over. The "Vylons" decide to exterminate the clans in order to prevent future wars.The clans once more band together in order to halt the "[[Vylon]]"," but it is the collaboration between the "Gem-Knights" and "[[Gishki]]" to whom credit for their eventual victory goes: "[[Gem-Knight Pearl]]" is the downfall of the "[[Vylon]]"." After the "Vylons" are driven back, the alliances between clans once again dissolve.The "[[Gishki]]" immediately resume their invasion of "[[Mist Valley]]"," which had been their main objective pre-"[[Steelswarm]]"." In order to obtain resources from the Valley, the "[[Gishki]]" enact a genocide on the "[[Gusto]]"." The Gem-Knights intervene to [[Daigusto Emeral|rescue the remaining]] "[[Gusto]]".When the "[[lswarm]]" virus begins to spread across the Duel Terminal world, the Gem-Knights join the "[[Gusto]]" in a prayer for the "[[Constellar]]," a legendary band of divine warriors, to aid them. The "[[Constellar]]" may not be strong enough to resist the "lswarm" army alone, as the "[[Gishki]]" clan falls to the virus. Knowing this, the "Gem-Knights" fuse into [[Gem-Knight Master DiaDiamond|the most powerful Gem-Knight]]. These are "[[Cairngorgon, 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''' Fusions Master Diamond" (left arm and right leg), and their components"Gem-Knight Prismaura" (damaged head).==Members=====Main Deck===; Normal Monster

 ==Play style== The "Gem-Knight" employs rapid A key monster to the archetype's general strategy is their LINK 2 [[Fusion Summon|FusionLink Monster]] "[[BeatdownGem-Knight Phantom Quartz]] strategy", who is both a searcher for all archetypal cards, accomplished with 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 four 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-Knight's [[Normal MonsterArmadillo]]s benefit from most "), Normal Monster support cards(e.g.: "[[Rescue Rabbit]]", as well as "[[Gem-MerchantUnexpected Dai]]"),or [[Rock]] support (e.g. "[[Adamancipator Researcher]]" whose effect resembles that of , "[[Blackwing - Kalut the Moon ShadowBlock Dragon]]"). "[[Crystal Rose]]" is an indirect searcher that can copy the name of any "Gem-Knight Alexandrite" monster in Deck (allowing it to be used as a Fusion or Link Material), and sends a "Gem-Knight" from Deck to GY, which can trigger floating effects. "[[Crystal Rose]]" and "[[Gem-ArmadilloBrilliant Rose]]" provide excellent search power both have effects to facilitate this strategySpecial Summon themselves and copy the name of a "Gem-Knight" monster, providing indirect searching for specific Fusion Materials. The To search out the archetype's key card is Fusion Spells, external "Fusion" support cards like "[[Predaplant Darlingtonia Cobra]]" and "[[Predaplant Ophrys Scorpio]]" can be used, but "Phantom Quartz" alone can be used to search out "[[Gem-Knight Fusion]]", which, apart from granting access to its vast arsenal of powerful Fusions, can return itself to the hand at the price of a then be repeatedly used and reused. "[[Gem-Knight banished from Quartz]]" can search out the Graveyard. powerful "[[DiscardBrilliant Fusion]] effects can come in handy: cards such as " and "[[Phoenix Wing Wind BlastScatter Fusion]]" can remove threats from the field, while also loading the Graveyard but has heavy restrictions attached to pay this costit. Two key "Gem-Knight" monsters, "[[D.D.R. Gem- Different Dimension ReincarnationKnight Obsidian]]" can re-Summon the Gem-Knights banished via and "[[Gem-Knight FusionLazuli]]", essentially rendering have non-once per turn effects that can recycle the cost moot player's monsters when sent to the GY, compensating for the costs of Fusion Summoning and restocking extending the hand with materials for another player's Fusion Summonplays. The release of both "[[Xyz MonsterGem-Knight Quartz]]" also has a GY recycle effect if it's and used as a Fusion Material, albeit being once-per-turn only.===Gem-Knight Beatdown===The intended strategy for the "Gem-Knight"archetype is likely a [[Rescue Rabbitbeatdown]]" give -focused one, focusing on Fusion Summoning multiple "Gem-KnightsKnight" another welcome boostFusion Monsters, use them to remove the opponent's cards, and defeat the opponent with the high ATK of the Fusion Monsters. "Rescue Rabbit" can bring out ===Gem-Knight FTK===This is an [[FTK]] strategy focused on using the materials for any effect of "[[Gem-KnightLady Lapis Lazuli]]" Fusion Monsters (or even Xyz Summoning and "[[Gem-Knight PearlMaster Diamond]]"), and (copying the effect of "Lady Lapis Lazuli") to repeatedly [[Gem-Knight Amberburn]]the opponent."Lady Lapis Lazuli" can return a banished Rabbit inflict 500 damage to the hand opponent for further usageeach Special Summoned monster on the field. However, "Lapis Lazuli" can only be Special Summoned once per turn, necessitating the use of "Master Diamond" to copy the effect of "Lady Lapis Lazuli" and reuse its effects. Generally, Gem-Knight FTK aims to swarm the player's own field with monsters and activate the effects of "Lady Lapis Lazuli" once and "Master Diamond" twice to inflict around 8000 damage to the opponent, achieving an FTK. === Recommended cards ==={{Decklist|Vanilla Style|normal monsters =*[[Elemental HERO PrismaGem-Knight Crystal]]* [[Gem-Knight Garnet]]*[[Gem-ArmadilloKnight Lapis]]*[[Gem-Knight AlexandriteSapphire]] (to summon Crystal easily)*[[Gem-Knight CrystalTourmaline]]|effect monsters =*[[Gem-Knight EmeraldAlexandrite]]*[[Gem-Knight GarnetEmerald]]*[[Gem-Knight Lazuli]]*[[Gem-Knight Obsidian]]*[[Gem-Knight SapphireQuartz]]* [[Brilliant Rose]]* [[Crystal Rose]]*[[Gem-Knight TourmalineArmadillo]]*[[Gem-Merchant]]*[[Gem-Turtle]]*[[Morphing JarBox of Friends]]*[[Rescue Rabbit]] (main engine of this style)* [[Predaplant Darlingtonia Cobra]] + [[Predaplant Ophrys Scorpio]]* [[Thunder Dragon]]<u>Extra deck</u>|gemini monsters =*[[Daigusto EmeralGem-Knight Amber]]*[[Fairy King AlbverdichGem-Knight Iolite]]* [[Gem-Knight Sardonyx]]|fusion monsters =*[[Gem-Knight Amethyst]]*[[Gem-Knight Aquamarine]]*[[Gem-Knight Citrine]]*[[Gem-Knight Master DiaLady Brilliant Diamond]]* [[Gem-Knight Lady Lapis Lazuli]]* [[Gem-Knight Lady Rose Diamond]]*[[Gem-Knight PearlMaster Diamond]]*[[Gem-Knight Prismaura]]*[[Gem-Knight Ruby]]*[[Gem-Knight SeraphiSeraphinite]]*[[Gem-Knight Topaz]]*[[Gem-Knight Zirconia]]*[[Lavalval ChainFirst of the Dragons]]* [[Thunder Dragon Colossus]] (OCG or Traditional Format only)* [[Thunder Dragon Titan]]|spells xyz monsters =*[[D.D.R.

===Weaknesses===* Anti-Fusion/Special Summoning floodgates, such as "[[Non-Fusion Area]]", "[[Archlord Kristya]]", "[[Dimensional Barrier]]", or "[[Domain of the True Monarchs]]" can completely shut off the deck's game plan.* Anti-Spell floodgates like "[[Naturia Beast]]" or "[[Imperial Order]]" can prevent the deck from using "[[Gem-Knight Fusion]]".* GY floodgates like "[[Macro Cosmos]]" can prevent the deck from recovering "Gem-Knight Fusion".* Most "Gem-Knight" decks use "[[Gem-Knight Phantom Quartz]]" as their only way to search "Gem-Knight Fusion", making it the deck's main chokepoint.==Trivia==* This archetype appears to be based on the "[[Elemental HERO]]" archetype, since a few of their monsters share similar stats (Level/ATK/DEF) and poses 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 |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 #123 |author=[[Kevin Tewart]] |date=July 21, 2011 |publisher=Pojo.com Forums}}</ref><ref>{{Decklistcite web |url=http://www.pojo.biz/board/showthread.php?p=22284193#post22284193 |Gemini Styletitle=<nowiki>[Official Thread]</nowiki> Hidden Arsenal 4 : Special Edition post #125 |author=[[Kevin Tewart]] |date=July 21, 2011 |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!

Like the [[Evil HERO]] [[archetype]], which relies on "[[Dark Fusion]]" and "[[Dark Calling]]", the Gem-Knights depends upon their "[[Gem-Knight Fusion]]" for their usual repeated Fusion Summons {{Archseries navbox (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]]," which can render it unusable for the rest of the Duel. "[[Non-Fusion Area]]" can also damage its play-style, blocking all attempts at Fusion Summoning, leaving the deck at a severe disadvantage. "[[Torrential Tribute]]" and "[[Needle Ceiling]]", 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. A more typical concern would be anti-Special Summon 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 like "[[Gemini Spark]]" can be used to handle threats of this nature. The same applies for cards like "[[Macro Cosmos]]" or "[[Dimensional Fissure]]," so that they will not disrupt the stream of Fusions. Cards such as "[[Mist Wurm]]", "[[Compulsory Evacuation Device]]" and "[[Neo-Spacian Grand Mole]]" can also get rid of your Gem-Knights Fusion Monsters (especially useful for dispatching "[[Gem-Knight Aquamarine]]" and "[[Gem-Knight Amethyst]]"Links). "[[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 "[[Rescue Rabbit]]" also included in the mix, since Rescue Rabbit can only Special Summon those Normal Monsters from the Deck. "[[Gem-Turtle]]" can sometimes provide a remedy, as it retrieves a copy 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 {{Archseries navbox ("[[Pot of Duality]]" can be used, but not only will it suspend Fusion Summoning for a turn, but it also may not work as intendedD Team).}} Sida "[[Gem-{{Knight Alexandrite]]" or "[[Rescue Rabbit]]" are also susceptible to "[[Mirror of Oaths]]", resulting a possibly loss of momentum. "[[Skill Drain]]" can also dangerous, since it will disable most in-field Gem-Knight Fusion Monster's effect such as "[[Gem-Knight Citrine]]", "[[Gem-Knight Prismaura]]" or "[[Gem-Knight Seraphi]]".}}{{Duel Terminal}}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 "[[Gem-Knight Fusion]]" in the Grave. "[[Summoner Monk]]" can quickly put "[[Lavalval Chain]]" on the field at the cost of a Spell Card, but be warnedCategory: it is susceptible to cards such as "[[Effect Veiler]]", "[[Bottomless Trap Hole]]" and "[[Solemn Warning]]." ==Trivia==* While seen mostly as a reference to both the "[[Elemental HERO]]" and "[[Crystal Beast]]" [[archetype]]s, "Gem-Knights" can also reference the Power Rangers/Super Sentai series (much like the "Elemental HERO" monsters pay tribute to American comic heroes).* It seems there once was a "Gem-Knight Heliotrope/Bloodstone," but it was infected by the "[[lswarm]]" TCG and became "[[Evilswarm Heliotrope]]."* Gem-Knights are all of one Attribute ([[EARTH]]), yet have a variety of Types, whereas "[[Elemental HERO]]" monsters are nearly all of one Type ([[WarriorOCG archetypes]]) but of different Attributes.{{Archetype navbox}}
