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-Knights" are EARTH, whereas their Type varies between Pyro, Thunder, Aqua, or Rock (with one 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 member, a Gemini member, and a Fusion member.
All members of this archetype are named after different minerals. Aesthetically, they appear to be a synthesis of Jesse Anderson's "Crystal Beasts" and Jaden Yuki's "Elemental HERO" cards, possibly as 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 "Gem-Knight" Normal Monsters are shown to be unarmed, the ten Fusion Monsters wield weapons befitting their stats 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 and shield. "Gem-Knight Zirconia," on the other hand, is equipped with gigantic fists seemingly to compensate for its lack of effect, "Gem-Knight Seraphinite" uses a saber, and "Gem-Knight Master Diamond" 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, only archetype to boast six "Polymerization"-styled cards: "Gem-Knight Fusion", "Particle Fusion", "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 1 "Gem-Knight" Monster, and with the assistance of "Gem-Knight Obsidian" and "Gem-Knight Lazuli" the user is allowed to recycle "Gem-Knight" Normal Monsters. As a result, the player can Fusion Summon several times from their Extra Deck during the same turn.
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 "Vylons". Along the way, they obtain 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 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 the most powerful Gem-Knight.
"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 Master Diamond" (left arm and right leg), and "Gem-Knight Prismaura" (damaged head).
The "Gem-Knight" employs rapid Fusion Beatdown strategy (similar to "Elemental HERO" monsters), accomplished with the use the archetype's six Fusion Spells/Traps and a wide array of recycling effects. The "Gem-Knight" Normal Monsters benefit from most Normal Monster support cards, as well as "Gem-Merchant", whose effect resembles that of "Blackwing - Kalut the Moon Shadow". "Gem-Knight Alexandrite" and "Gem-Armadillo" provide excellent search power to facilitate this strategy.
The archetype's key card is "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 "Gem-Knight" banished from the Graveyard. Discard effects can come in handy: cards such as "Phoenix Wing Wind Blast" can remove threats from the field, while also loading the Graveyard to pay this cost. "D.D.R. - Different Dimension Reincarnation" and "Chaos Zone" can re-Summon the "Gem-Knights" banished via "Gem-Knight Fusion", essentially rendering the cost moot and restocking the hand with materials for another Fusion Summon.
Since you can Fusion Summon Gem-Knights using other Gem-Knight Fusion monsters, a Gem-Knight deck can use the effects of Amethyst and Aquamarine to eliminate troublesome Trap Cards and return monsters to the hand, making the field safer for cards like Gem-Knight Prismaura, Gem-Knight Citrine, and Gem-Knight Ruby.
Pairing "Gem-Knight Master Diamond" with the Field Spell "Catapult Zone" is also a good tactic. As the effect of "Master Diamond" allows it to gain 100 ATK with every "Gem-Knight" in the Graveyard, it's prevented from getting destroyed by battle once per turn and send one Rock-Type from the Deck to the Graveyard instead. By feeding in cards such as "Gem-Knight Lazuli", it's ATK will steadily rise over 3000, which causes it to become less vulnerable and it can come in handy when dealing with cards such as "Hieratic Sun Dragon Overlord of Heliopolis".
The release of both Xyz Monsters and "Rescue Rabbit" give "Gem-Knights" another welcome boost. "Rescue Rabbit" can bring out the materials for any "Gem-Knight" Fusion Monsters (or even Xyz Summoning "Gem-Knight Pearl"), and the effect of "Gem-Knight Amber" can return a banished "Rabbit" to the hand for further usage.
With the release of Brilliant Fusion, Gem Knights gained more extremely powerful support that allows them to Fusion Summon using Materials from the Deck, at the cost of the Summoned monster having 0 ATK/DEF. This lead to Brilliant Fusion being played in many Decks simply to Fusion Summon Gem-Knight Seraphinite to obtain an extra Normal Summon (see Engine), but it is also extremely powerful in a dedicated Gem-Knight Deck, especially one built with a few off-archetype monsters to access monsters like Seraphinite. Simply use the Summoned monster's effects, then Fuse it into something even bigger, reviving the Summoned monster later as Brilliant Fusion does Fusion Summon, so the monster was properly Summoned.
With the release of Link Format, Gem-Knights initially suffered, but with the release of Gem-Knight Phantom Quartz, an FTK was discovered using Gem-Knight Lady Lapis Lazuli to repeatedly burn the opponent, Gem-Knight Master Diamond to re-use the effect and Phantom Quartz to recycle monsters while Summoning more Fusion Monsters. This lead to Master Diamond being Limited, and the Deck has since once more faded from the competitive scene, barring Brilliant Fusion, which continues to be a staple for many Decks.
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-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), 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 (plus "Anti-Fusion Device" and "Steelswarm Sting" can expunge Fusions on the field). "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 but not for cards like "Dark Hole", "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 cards.
A more typical concern would be 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 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", "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 "Gem-Knight Aquamarine" 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 "Rescue Rabbit" also included in the mix, since "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 ("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 "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 "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 "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 it is returned to the hand. Finally, "Gem-Knights" alone have no way of bouncing back into play once they're banished, making "Macro" Decks a mismatch for them.
The introduction of the Extra Monster Zone severely weakens the Deck's ability to Fusion Summon multiple "Gem-Knights" at once, though the introduction of Gem-Knight Phantom Quartz does somewhat mitigate this.
- This archetype appears to be based on the "Elemental HERO" archetype, since a few of their monsters' poses are based on the poses of the "Elemental HERO" monsters.
- "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.
