From left to right: "Alexandrite", "Lapis" and "Emerald"
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 Attribute, whereas Type varies between Pyro, Thunder, Aqua, or Rock (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 member, a Gemini member and a Fusion Monster.
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 a 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 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 Lapislazuli," which deals effect damage, is depicted without any weapon.
"Gem-Knight" is the first, and so far, the only archetype to boast five "Polymerization"-styled cards: "Gem-Knight Fusion", "Particle Fusion", "Pyroxene Fusion", "Absorb Fusion" and "Fragment 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, and with the assistance of "Gem-Knight Obsidian" and "Gem-Knight Lazuli" the user is allowed to recycle "Gem-Knight" normal monsters. Because of this, 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.
"Dark-line Warrior Caingorgorm" 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) and "Gem-Knight Master Diamond" (left arm and right leg, plus part of the helmet).
These are the Gem-Knight Fusions and their components.
|Gem-Knight Fusion||Fusion Material 1||Fusion Material 2||Fusion Material 3|
|Gem-Knight Aquamarine||Gem-Knight Sapphire||Gem-Knight|
|Gem-Knight Ruby||Gem-Knight Garnet||Gem-Knight|
|Gem-Knight Topaz||Gem-Knight Tourmaline||Gem-Knight|
|Gem-Knight Master Diamond||Gem-Knight||Gem-Knight||Gem-Knight|
|Gem-Knight Lady Lapislazuli||Gem-Knight Lapis||Gem-Knight|
These are the Gem-Knight cards and the Gem/Creature that they are based off.
The "Gem-Knight" employs rapid Fusion Beatdown strategy (similar to "Elemental HERO" monsters), accomplished with the use the archetype's five Fusion Spells/Traps and a wide array of recycling effects. The Gem-Knight's 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.
Pairing "Gem-Knight Master Diamond" with the field spell "Catapult Zone" is also a good tactic. As Gem-Knight Master Diamond's effect allows it to gain 100 attack points 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.
Despite its speed and flexibility, Gem-Knights are not without weaknesses. 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 (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").
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 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 ("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 Grave. "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 "Gem-Knight Citrine", "Gem-Knight 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-Knight"s alone have no way of bouncing back into play once they're banished, making Macro Decks a mismatch for them.
- While seen mostly as a reference to both the "Elemental HERO" and "Crystal Beast" archetypes, "Gem-Knights" can also reference the Power Rangers/Super Sentai series (much like the "Elemental HERO" monsters pay tribute to American comic's
- Gem-Knights are all of one Attribute (EARTH), yet have a variety of Types, whereas most "Elemental HERO" monsters are nearly all of one Type (Warrior) but of different Attributes.
