{{Infobox/Yu-Gi-Oh!/Archetype/End}} "'''Koa'ki Meiru'''", sometimes romanized as Japanese for "'''Core ChimairChimail''' " (a combination of the words "Core" and "Chimeraコアキメイル ''Koakimeiru'')," is a theme from an [[Raging Battlearchetype]], debuted in ''[[Ancient ProphecyRaging Battle]], [[Stardust Overdrive]], ''.==Lore=={{Main|Master Guide 3 card storylines#File Number 05: Koa'ki Meiru}}According to "[[Absolute PowerforceIron Core Specimen Lab]]", and "[[The Shining DarknessKozaky]]). However the support card " and "[[Magical Scientist]]" experimented and created the "Koa'ki Ring]]Meiru" and other anti-meta cards appear in [[Starstrike Blast]]Monsters. The majority of their effects center around manipulating the [[Iron Core of ==Etymology=="Koa'ki Meiru]] or revealing one in hand to activate an effect. The strongest " is a combination of the words "Core", "Chimera" and "Mail", sometimes romanized as "Core Chimair" (a combination of the monsters require a maintenance cost in the form words "Core" and "Chimera").==Design==The "Koa'ki Meiru" archetype consists of sending an Iron Core to the grave or revealing a monster plethora of the same type. There are exceptions such different creatures, featuring elementals, dragons, statues, warriors and many more and can overall be described as that a mishmash of [[Koaart styles. They don'ki Meiru Powerhand]]t really have any connection in design or color, where you must reveal a [[Normal Trap Cards|Normal Trap Card]]except for the fact that all of the "Koa'ki Meirus" have the same mark (3 dragons) on some part of their body or on a weapon they use.==Playing style=="Koa'ki Meirus are all Meiru" is a [[EARTHstun]], /[[WINDcontrol]], Deck revolving around fulfilling its monsters' [[WATERmaintenance cost]] or [[FIRE]] attributes, rendering s in order to keep them immune to on the field and apply their own control based field-controlling effects which often affect . Secondarily, the archetype revolves around interactions with the Normal Spell "[[LIGHT]] and [[DARKIron Core of Koa'ki Meiru]] monsters". All of the Almost every "Koa'ki Meiru" have monster has a maintenance cost that must be performed during each of the same mark (3 dragons) on some part of their body or on a weapon player's [[End Phase]]s, otherwise they havewill destroy themselves. Also, many "Koa'ki Meiru and related cards" monsters typically have a choice of two actions for their maintenance costs; the options are typically sending an "Iron Core" from the player' artwork uses yellows hand to the Graveyard, orange, and red, except [[Koaor revealing a card in the player'ki Meiru Ghoulungulate]]s hand (typically a monster of their same type). ==Playing Style{| class="wikitable mw-collapsible autocollapse" style="margin-left: auto; margin-right: auto; border: none; text-align: center" The theme was initially designed to bring down the dominating decks of over 2 banlists therefore centering around heavy control elements.

Option 1! Option 2|-| [[DARK]] decks, effects specifically targeted both Attributes therefore bringing about a specific Meta, Anti Meta theme. Because of their high [[ATK]], 11 Level 4 monsters from 1900 ATK, topping out at 3000 ([[KoaKoa'ki Meiru ValafarMaximus|Maximus]]), and the nature of the new support, the theme has taken a more aggressive approach with powerful beatdown elements, namely [[|| 8 || WIND || Dragon| rowspan = 20 | Send 1 "Iron Core"| Send 1 "Koa'ki Meiru Rooklord]] and " monster|-| [[Koa'ki Meiru UrnightValafar|Valafar]]. Generally speaking, there are two ways to use || 8 || FIRE || Fiend| —|-| [[Koa'ki Meiru cards. The most obvious is to simply use a dedicated deck; the other being to use individual Rooklord|Rooklord]] || 7 || EARTH || Warrior| Reveal 1 Warrior monster|-| [[Koa'ki Meiru monsters as a supplement to Type specific decks of their type, giving an [[Anti-MetaGhoulungulate|Ghoulungulate]], controlling aspect to it as well as being able to maintain it through the alternative maintenance cost; for example, using || 5 || EARTH || Zombie| Reveal 1 Zombie monster|-| [[Koa'ki Meiru DragoPowerhand|Powerhand]] in a [[Dragon]] type deck as seen in || 4 || EARTH || Machine| Reveal 1 Normal Trap|-| [[Disaster Dragon]] builds. In order to run a Koa'ki Meiru deck, no matter the style, you'll need multiple ways to retrieve the [[Iron Core of Koa'ki MeiruUrnight|Urnight]] from your deck and graveyard such as [[Koa'ki Meiru Boulder]], || 4 || EARTH || Beast-Warrior| Reveal 1 Beast-Warrior monster|-| [[Koa'ki Meiru CrusaderBergzak|Bergzak]], and || 4 || EARTH || Warrior| Reveal 1 Warrior monster|-| [[Core Transport UnitKoa'ki Meiru Drago|Drago]]. || 4 || WIND || Dragon| Reveal 1 Dragon monster|-| [[Iron Core Immediate DisposalKoa'ki Meiru Beetle|Beetle]] is also nice mid game, after building up resources in hand. You must also be wary of keeping more on field than you can maintain. Your field should max out at 2 Koa'Ki Meiru's requiring maintenance with multiple Cores in play as well as an alternative cost ready in hand. Beatdown uses a different lineup, using a minimum of control but only the best in the form of || 4 || EARTH || Insect| Reveal 1 Insect monster|-| [[Koa'ki Meiru RooklordCrusader|RooklordCrusader]] and || 4 || EARTH || Beast-Warrior| Reveal 1 Beast-Warrior monster|-| [[Koa'ki Meiru DragoGravirose|DragoGravirose]].

Also, having multiple Koa'ki Meiru monsters on the field at once can be extremely dangerous, as each one would require you to reveal or discard a card from your hand at the End Phase; leaving hand and field advantage very hard to maintain, unless multiple copies are used (for example, 3 Doom|Doom]] || 3 || WIND || Fiend| Reveal 1 Fiend monster|-| [[Koa'ki Meiru Powerhands only require 1 Normal Trap Card revealed).

Most of the monsters are used against [[Effect Monstersand "[[Koa'ki Meiru Doom|Doom]], mostly ") have effects focused on countering [[DARKLIGHT]] and [[LIGHTDARK]] monsters, since they are the commonly used decks ([[Infernities]], [[Lightsworns]], [[Blackwings]] etc.(which were likely intended as "anti-meta" options against their contemporary LIGHT and DARK-based meta Decks). Most Four Level 4 EARTH Rock "Koa'ki Meiru decks should focus on " monsters ("[[RockKoa'ki Meiru Overload|Overload]]-", "[[Type]Koa'ki Meiru Guardian|Guardian]] and ", "[[Beast-WarriorKoa'ki Meiru Sandman|Sandman]]-", "[[Type]] monsters, using other Types according to the deck's main strategy. Often overlooked is the fact that you can use "[[Iron Core ArmorKoa'ki Meiru Wall|Wall]]" to substitute for the maintenance cost ) also form a thematic sub-series with a single effect pattern: each of Koa'ki Meiru monsters. The main advantage of including "them can [[Iron Core Armornegate]]" in your deck is that there exists plenty an opponent's action (summoning a monster or activating a card/effect of support for [[Equip Spell Cards]]a card type) by tributing themselves. For example, using "[[Hidden Armory]]Koa'ki Meiru" to search for "[[Iron Core Armor]]" from your deck cards can be played as staples in other Typing-focused Decks, or graveyard may cause you to have one played as a single dedicated Deck. As a dedicated "Koa'ki Meiru monster sent to your graveyard" Deck, which could be used to fuel the effect of Deck primarily focuses on the Level 4 EARTH Rock "[[Koa'ki Meiru Ghoulungulate]]". monsters due to their accessibility, power, and synergy with [[Trade-InRock]] can work well if using support; they form a part of the popular "[[Beast King BarbarosRock Stun]] to reveal for [[" Deck.The Deck's main searchers are "[[Diamond Core of Koa'ki Meiru]]", "[[Koa'ki Meiru Urnight]] ", and "[[Koa'ki Meiru CrusaderSupplier]]". Other level 8 monsters to work with [[Trade-In]] are [[Aside from the "Rock Stun" "Koa'ki Meiru Valafar]]" monsters, other relevant high-power (and [[Koalow-cost) "Koa'ki Meiru Maximus]]. Maximus can also reveal for " monsters include the LIGHT and DARK hard counters "[[Koa'ki Meiru Drago]] " and Valafar is a strong beatstick that is immune to "[[Torrential Tribute]Koa'ki Meiru Doom]]", the card-destroying "[[Bottomless Trap HoleKoa'ki Meiru Ice]], " and "[[Mirror ForceKoa'ki Meiru Tornado]]", and the mass effect negation of "[[Call of the Haunted]], and [[Core ReinforcementKoa'ki Meiru Hydro Barrier]]". It would be wise While "Iron Core of Koa'ki Meiru" is central to include cards that return monsters the archetype's playstyle, and other cards to yours or your opponents handsthere are multiple dedicated searchers for it (e.g. Copies of "[[Compulsory Evacuation DeviceCore Transport Unit]] or [[Penguin Soldier]], "), the fact that the card doesn't have any effects itself and is purely an enabler for example, can both remove threats from the field or keep a certain specific cards means that more modern "Koa'ki Meiru alive for a turn" will typically try to downplay its importance, or even using him for the in favor of other external enablers (and maintenance.  Usual Anti-Meta tricks cost providers) like "[[Grave of the Super Ancient OrganismAdamancipator]] or [[Royal Oppression]] works fairly well, since Koa'ki Meirus can mantain a solid game even without Special Summoning.  Although most Koa'ki Meiru monsters have difficulty staying on the field, a few of them work incredibly well together, sharing types, or common reveals that help ensure their survival on the field.  With the release of the [[Machine Emperors]] in the [[OCG]] the Koa'ki Meiru can evolve and expand their [[Anti-Meta]] to an anti-synchro level, the advantage of running the machine emperors lies in the self-destruction effects that is common among the koa'ki meiru and also that all of them except [[Machine Emperor Wisel Infinity]] are not [[DARK]] or [[LIGHT]] attribute rending them immune to the [[Anti-Meta]] effects shared among the archetype. while also combining with the effect of [[Iron Core Specimen Lab]] to search for key monsters such as [[Koa'ki Meiru Urnight]]. * [[Koa'ki Meiru Urnight]] and [[Koa'ki Meiru Crusader]] share the [[Beast-Warrior]] type, and reveal requirement, while allowing for a good presence on the field and card advantage.  * [[Koa'ki Meiru Wall]], [[Koa'ki Meiru Sandman]], [[Koa'ki Meiru Guardian]], [[Koa'ki Meiru Boulder]], [[Koa'ki Meiru Prototype]] and [[Gigantes]] can be extremely aggressive when combined, as well as controlling the field and hand.  * [[Koa'ki Meiru Maximus]] can be used as the reveal cost for [[Koa'ki Meiru Drago]]. Drago's effect serves as disruption, while you gather [[Iron Core of Koa'ki Meiru]] for Maximus's final push for game.  * [[Koa'ki Meiru Doom]] and [[Koa'ki Meiru Valafar]] also work together, usually on its own deck revolving around [[Evil Hero Dark Gaia]] and [[Dark Fusion]]. * [[Koa'ki Meiru Speeder]] can null the costs for [[Koa'ki Meiru Tornado]] and [[Koa'ki Meiru Hydro Barrier]], as well as working with [[Koa'ki Meiru Powerhand]] due to their high ATK and DEF and low Levels. * [[Koa'ki Meiru Ghoulungulate]] has a protection effect, which can be achieved easily by building up a good graveyard size with [[Iron Core Specimen Lab]] and [[Koa'ki Meiru Urnight]]. [[Koa'ki Meiru Ghoulungulate]] can easily be brought out with [[Pyramid Turtle]]'s effect, and keeps a good Tribute fodder for [[Koa'ki Meiru Rooklord]]. Since both [[Remove from Play]], [[Burial from a Different Dimension]], and [[Return from the Different Dimension]] can be very powerful. Finally, a few cards have a usually heavy cost of discarding a [[Spell Card]] from your hand (like [[Summoner Monk]], [[Cursed Seal of the Forbidden Spell]] and [[Chiron the Mage]]), but Koa'ki Meiru decks can recycle the [[Iron Core of Koa'ki Meiru]] as long as they want to, making these much more consistent than any other deck. ===Recommended Cards=======Monster Cards====[[Rock]](For [[Koa'ki Meiru Guardian]]/[[Koa'ki Meiru Sandman]]/[[Koa'ki Meiru Wall]])* [[Gigantes]]* [[Neo-Spacian Grand Mole]]* [[Legendary Jujitsu Master]] [[Beast-Warrior]] (For [[Koa'ki Meiru Crusader]]/[[Koa'ki Meiru Urnight]])* [[Beast King Barbaros]]* [[Chiron the Mage]]* [[Pitch-Black Warwolf]] [[Warrior]] (For [[Koa'ki Meiru Bergzak]]/[[Koa'ki Meiru Rooklord]]/[[Koa'ki Meiru War Arms]])* [[D.D.

If the player is not careful and summons multiple "Koa'ki Meiru" monsters to the field without thought, it can easily blow up if one is not able to pay all the costs.** Additionally, cards such as "[[Respect Play]]" or "[[Ceremonial Bell]]" can eliminate the majority of the alternative maintenance costs by making it impossible to reveal any cards. In that case, one would be forced to rely on sending "Iron Core" to satisfy maintenance costs.* "Koa'ki Meiru" monsters are very reliant on the hand, therefore any form of "Hand Control" presents a big threat by being able to specifically remove assets essential to the Deck. Cards like "[[Card Destruction]]", "[[Mind Crush]]", "[[D.D. Designator]]" and "[[Royal OppressionTrap Dustshoot]]" can completely disrupt the player's strategy.* Like many other decks, "Koa'ki Meiru" does not appreciate its Summons to be negated or blocked. "[[Solemn Warning]]", "[[Solemn Judgment]]", "[[Archlord Kristya]]", "[[Vanity's Fiend]]" or "[[Mirror ForceVanity's Emptiness]]" are all effective against the deck.{{Archseries navbox}}{{ArchetypeNavboxArchseries navbox (Duel Links)}}[[Category:ArchetypesTCG and OCG archetypes]]
