'''Gemini monsters''' (Japanese: デュアルモンスター ''Dyuarumonsutā'' * This card can be [[Searcher|searched]] by "[[Fossil Dig]]", "Dual Monster[[Souleating Oviraptor]]", ") are [[Effect MonsterPetiteranodon]]s with the ", "[[Beta Evolution Pill - Ultranscendance]]", "[[Doodlebook - Uh uh uh!]]", "[[Miscellaneousaurus]]", "[[Miracle Jurassic Egg]]", "[[Ninjitsu Art of Super-Transformation]]", "[[abilityGiant Rat]] "Gemini, ". They have [[card effect|effectsBOXer]]", but these effects must be "unlocked[[Frontline Observer]]", " by performing an additional [[Normal SummonRescue Ferret]] on them while they are face", "[[Chaos-up on End Master]]", "[[Umbramirage the field; until thenElemental Lord]]", they are "[[treated as a Normal Monster|treated as Normal MonstersSangan]]", another copy of "[[Dinovader Docus]] on the field ", and in the Graveyard (everywhere else they are treated as Effect other [[List of generic searchers#Monsters)|generic searchers]].

The process of Normal Summoning a Gemini monster a second time (that is being treated as a Normal Monster by its effect) is just the same as performing any other Normal Summon, except that the monster is already on the field and no Tributes are necessary for Gemini monsters of Level 5 or above. Despite common unofficial usage, Normal Summoning a Gemini monster while it is already on the field is not called a "Gemini Summon". Once a Gemini monster has been Summoned an additional time, it is then treated as an Effect Monster and it gains the effect(s) written on it. Gemini monsters debuted in ''[[Tactical Evolution]]''. The most recent Gemini card text reads as follows: :''This card is treated as a Normal Monster while face-up on the field or in the Graveyard. While this card is a Normal Monster on the field, you can Normal Summon it to have it become an Effect Monster with this effect.<br/>● [Effect]'' So far, Gemini monsters have yet to make a proper appearance in the anime or manga. However, several members have made brief appearances in ''[[Yu-Gi-Oh! 5D's]]'', ''[[Yu-Gi-Oh! ZEXAL]]'' and ''[[Yu-Gi-Oh! ARC-V]]''. "[[Phoenix Gearfried]]" is on the poster for the [[World Racing Grand Prix]], "[[Gigaplant]]" appears in a flashback of [[Akiza Izinski]]'s past and "[[Crusader of Endymion]]" has been seen played by random [[Duelist]]s in {{episode|Yu-Gi-Oh! 5D's|114}} as well as {{episode|Yu-Gi-Oh! ZEXAL|1}}. Multiple copies of "[[Ancient Gear Knight]]" are used by members of [[Duel Academy (ARC-V)|Duel Academy]] during their [[Invasion of Xyz Dimension|invasion]] of [[Heartland City (ARC-V)|Heartland City]] in {{episode|Yu-Gi-Oh! ARC-V|36}}. [[Rin]] used "[[Lucky Pied Piper]]" in a flashback in {{episode|Yu-Gi-Oh! ARC-V|54}} The "[[Chemical Beast]]" archetype is heavily focused on, and almost completely composed of, Gemini monsters. ==Playing styleList ==Decks built entirely around Gemini monsters are almost all * [[Aggro]] Decks with strong field control, some capacity for field-[[swarm]]ing, and quick Synchro. However, the main strength of this archetype is versatility. Gemini Decks can vary greatly in specialty and method of operation, so much so that (unlike many archetypes) any two examples could be almost entirely different outside of two or three monsters and traps. The major types of Gemini Decks are Field Control (which tend to focus on destruction effects), Equip (which focus on Equips and often lean towards [[WarriorLevel]] Gemini monsters), 6 and the most popular: "Gigavise" (which focuses on abuse of the effect of "Gigaplant" effect to field-swarm [[Plant]]s or Geminis, sometimes going for the [[Gigaplant OTK]]). Some may include elements of all these types. Now, with the debut of [[Xyz Monster]]s, Decks that revolves on Level 4 or lower Gemini and non-Gemini monsters has good potential in conducting a quick Xyz Summon of Rank 4 or lower Xyz Monsters. Gemini monsters have seen an upswing recently in inclusion in anti-meta Decks, with the powerful beatsticks ("Elemental Hero Neos Alius" and "Crusader of Endymion") splashing in with support from "[[Honest]Dinosaur]" and "[[Gemini Spark]]". The [[Fusion Monster]] "[[Superalloy Beast Raptinusmonster]]" causes them to gain their effects immediately, and can be fused from any two Gemini. "Elemental HERO Neos Alius" is an ideal Fusion Material Monster for the "[[Elemental HERO]]" fusions with non-specific fusion material based on the different Attributes. What makes it really impressive is the use of "[[Super Polymerization]]", enabling not only discards (which are beneficial to a Deck of this kind) but the theft of certain monsters depending on attribute. They benefit greatly from the many support cards that allow Normal Monsters to be Summoned back from the Graveyard, like "[[Birthright]]". Gemini monsters can play an important role in Decks based around Normal Monsters. A good example of this is "[[Cú Chulainn the Awakened]]", seeing as he can use the [[ATK]] of a Normal Monster in the Graveyard. ===Further strategy===If your Gemini Deck consist of utilizing level 4 Gemini monsters, adding in "Gemini Spark” would be extremely effective in dodging inevitable trap cards or removing any target on the field. What makes "Gemini Spark" effective is the ability to chain it to an opponent's card such as "[[Bottomless Trap Hole]]", which not only saves your monster from being banished but also enabling you to draw 1 card. In addition, "Gemini Spark" also benefits Gemini monsters such as "[[Blazewing Butterfly]]" which depends on a Gemini in your Graveyard. In Gemini decks that focus on gaining the effect of “Gemini” monsters, running "[[Supervise]]" is a must. Combos with “Supervise” involve “[[Evocator Chevalier]]” which destroys any card your opponent controls and reviving a Normal Monster from your Graveyard. Since "Gemini" monsters are Normal Monsters while in your graveyard, adding "[[Swing of Memories]]" can be of great use. This card proves versatile with the addition of Xyz Monsters, one may summon a monster on the field then use "Swing of Memories" to revive a Gemini in the graveyard, which will then set-up for an easy Xyz Summon (since most Geminis are level 4), a Tribute Summon (such as "[[Knight of the Red Lotus]]") or Synchro Special Summon if a tuner is available.  "Knight of the Red Lotus" is another great addition for a Gemini deck. This card resurrects a Gemini monster from your graveyard every turn. Although this card is a tribute summon, you may special summon it if the requirements are met. Xyz Monsters such as “[[Daigusto Emeral]]” may also be of great assistance in reviving a Gemini from your Graveyard. Gemini decks that specialize in sending your Gemini monsters to the graveyard often would use cards such as Future fusioned, "[[Foolish Burial]]" or Featherizer. "[[Future Fusion]]" will send two of your Gemini monsters to your Graveyard (best to send "Gemini" monsters that require Tribute) which will then allow you to Summon "Superalloy Beast Raptinus" in a few Standby Phases. "[[Featherizer]]" will send a "Gemini" from your Deck to your Graveyard and allowing you to draw 1 card after being destroyed sorted by battle. ==Weaknesses==All Decks that deal with Gemini are extremely vulnerable to commonly played cards such as "[[Book of Moon]]" (which can reset the effects of Gemini monsters) and "Bottomless Trap Hole" (which not only stops their Summon, but removes them from play). Another problem with pure Gemini Decks is speed. Even when built for field-swarming, Gemini Decks can have a hard time matching the speed of the most commonly played archetypes that specialize in it, such as "[[X-Saber]]s", "[[Blackwing]]s", and "[[Lightsworn]]s". Other weaknesses include "[[Fortune Lady]]" Decks because of their Field Spell "[[Future Visions]]", which prevents Gemini monsters from gaining their effects, and "[[Black Garden]]", which would cut down the [[ATK]] down to a quarter before it would gain its effects. Also, Gemini monsters tend to rely more heavily on support cards than some archetypes, so Decks built around them more typically go over the forty card standard than others.Level:{{Decklist|Recommended cardsCard query|monsters =<u>Normal Monsters</u> * [[Tune WarriorType::Dinosaur]]* [[Flamvell Guard]]<u>Effect MonstersLevel::</u>* [[Darkstorm Dragon6]]* [[Phoenix Gearfried]]* [[Chthonian Emperor Dragon]]* [[Evocator Chevalier]]* [[Heavy Knight of the Flame]]* [[Flamvell Firedog]]* [[Dark Valkyria]]* [[Featherizer]]* [[Gemini Soldier]]* [[Blazewing Butterfly]]* [[Future Samurai]]* [[Tuned Magician]]* [[Energy Bravery]]* [[Gemini Scorpion]]* [[Knight of the Red Lotus]]* [[Woodland Archer]]* [[Vylon Prism]]* [[Vylon Stella]]* [[Ancient Gear Knight]]* [[Gemini Soldier]]<u>Extra Deck</u>* [[First of the Dragons]]* [[Power Tool Dragon]]* [[Black Brutdrago]]* [[Superalloy Beast Raptinus]]* [[Dragon Knight Draco-Equiste]]* [[Colossal Fighter]]* [[Stardust Dragon]]* [[Red Dragon Archfiend]]* [[Thought Ruler Archfiend]]* [[Number 39Summoning:: Utopia]]* [[Daigusto Emeral]]* [[Thunder End Dragon]]|spells =* [[Supervise]]* [[Gemini Spark]]* [[Dragon's Mirror]]* [[Polymerization]]* [[Unleash Your Power!]]* [[Herculean Power]]* [[Silent Doom]]* [[Symbols of Duty]]* [[Swing of Memories]]* [[Double Summon]]* [[Super Double Summon]]* [[Hidden Armory]]* [[Ekibyo Drakmord]]* [[Dark Factory of Mass Production]]* [[Reinforcement of the Army]]* [[Monster Reincarnation]]* [[Rekindling]]|traps =* [[Ultimate Offering]]* [[Gemini Trap Hole]]* [[Gemini Counter]]* [[Gemini Booster]]* [[Birthright]]* [[Call of the Haunted]]* [[Justi-Break]]* [[Reinforce Truth]]}} ==Gemini Toolbox==This deck is focused on having the most functionality and focuses on monster effects and fast Synchro or Xyz Summon.
