{{Infobox/Yu-Gi-Oh!/Archetype/End}} "'''Koa'ki Meiru'''", known in the OCG as Japanese for "'''Core Chimail''' " (a combination of the words "Core", "Chimera" and "Mail"コアキメイル ''Koakimeiru''), sometimes romanized as is an [[archetype]] debuted in ''[[Raging Battle]]'Core Chimair'.==Lore=={{Main|Master Guide 3 card storylines#File Number 05: Koa'' (a combination of the words ki Meiru}}According to "[[Iron CoreSpecimen Lab]]" and "Chimera,") is a theme from [[Raging BattleKozaky]], " and "[[Ancient ProphecyMagical Scientist]], [[Stardust Overdrive]], [[Absolute Powerforce]], and [[The Shining Darkness]]. However, the support card "[[experimented and created the "Koa'ki Ring]]Meiru" and other anti-meta cards appear in [[Starstrike Blast]].Monsters.==Etymology== The majority of their effects center around manipulating the "[[Iron Core of Koa'ki Meiru]]" or [[reveal]]ing one in your hand to activate an effect. Almost all is a combination of the monsters require a maintenance cost in the form of sending an Iron words "Core to the grave or revealing ", "Chimera" and "Mail", sometimes romanized as "Core Chimair" (a monster combination of the same type. There are exceptions, such as that of words "Core" and "Chimera").==Design==The "[[Koa'ki Meiru Powerhand]]", where you must reveal archetype consists of a [[Normal Trap Card]]plethora of different creatures, featuring elementals, dragons, statues, warriors and many more and can overall be described as a mishmash of art styles. They don't really have any connection in design or color, except for the fact that all of the "[[Koa'ki Meiru Valafar]]Meirus" where you have to send an "Iron Core the same mark (3 dragons) on some part of Koa'Ki Meiru" and cannot reveal any card in your hand insteadtheir body or on a weapon they use.==Playing style=="Koa'ki Meiru are all " is a [[EARTHstun]], /[[WINDcontrol]], Deck revolving around fulfilling its monsters' [[WATERmaintenance cost]] or [[FIRE]] attribute monsters, 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' artwork uses yellow, orange, and red, except for "[[Koa'ki Meiru Ghoulungulate]]". According to monsters typically have a choice of two actions for their maintenance costs; the options are typically sending an "[[Iron Core Specimen Lab]]", "[[Kozaky]]" and "[[Magical Scientist]]" experimented and created from the player's hand to the Graveyard, or revealing a card in the Koaplayer'ki Meiru Monsterss hand (typically a monster of their same type).{| class="wikitable mw-collapsible autocollapse" style=Playing Style==The theme was initially designed to bring down the dominating Decks of over 2 banlists and therefore centered around heavy control elements.

"|| 4 || EARTH || Rock| Reveal 1 Rock monster|-| [[Iron Core Immediate Disposal]]" is also nice mid game after building up resources in your hand.

A number of "Koa'ki Meiru Powerhands" only require 1 Normal Trap Card revealed)monsters (e.g. A good way to avoid problems with this is to keep a duplicate of the specific monsters in your hand-usually, "[[Koa'Ki ki Meiru Monsters require you to reveal a monster of the same type so you can reveal a duplicate or another Drago|Drago]]" and "[[Koa'ki Meiru of the same type. Koa'ki Meiru monsters are very reliant on the hand and so cards like "[[Card DestructionDoom|Doom]]", ") have effects focused on countering [[Mind CrushLIGHT]]", or "and [[D.D. DesignatorDARK]]monsters (which were likely intended as " can completely disrupt the player's strategy and cards like anti-meta" options against their contemporary LIGHT and DARK-based meta Decks).Four Level 4 EARTH Rock "Koa'ki Meiru" monsters ("[[Trap DustshootKoa'ki Meiru Overload|Overload]]" or even , "[[Des KoalaKoa'ki Meiru Guardian|Guardian]]" can deal serious damage. One way to beat the , "[[Koa'ki Meiru format is to have the opponent permanently reveal their hand to you on their turns in order to make them either discard an Sandman|Sandman]]", "Iron Core of [[Koa'ki MeiruWall|Wall]]" or destroy the card since they cannot "reveal" the card to you. Such cards include ") also form a thematic sub-series with a single effect pattern: each of them can [[Respect Playnegate]]" and "[[Ceremonial Bell]]"an opponent's action (summoning a monster or activating a card/effect of a card type) by tributing themselves. [[Remove from play]] Decks can remove "[[Iron Core of Koa'ki Meiru]]" and so you have to rely on your revealing effect. To protect yourself from thiscards can be played as staples in other Typing-focused Decks, it is or played as a good idea to have "[[Necrovalley]]" and single dedicated Deck. As a dedicated "[[Burial from a Different Dimension]]Koa'ki Meiru" in your [[Side Deck]].  Hand Control Decks present , the biggest threat by being able to specifically remove assets essential to Deck primarily focuses on the Deck. ==Playing Tips==This Deck revolves around [[Anti-Meta]]. Obviously, the most important card in the Deck is Level 4 EARTH Rock "[[Iron Core of Koa'ki Meiru" monsters due to their accessibility, power, and synergy with [[Rock]]", so having three in your Deck is support; they form a must. Most part of the monsters are used against popular "[[Effect MonstersRock Stun]], mostly " Deck.The Deck's main searchers are "[[DARKDiamond Core of Koa'ki Meiru]] and ", "[[LIGHT]] monsters, since they are the commonly used Decks ([[Infernities]], [[LightswornsKoa'ki Meiru Urnight]]", and "[[Blackwings]] etc.). Most Koa'ki Meiru Decks should focus on [[Rock]]-[[TypeSupplier]] ". Aside from the "Rock Stun" "Koa'ki Meiru" monsters, other relevant high-power (and [[Beastlow-Warriorcost) "Koa'ki Meiru" monsters include the LIGHT and DARK hard counters "[[Koa'ki Meiru Drago]]-" and "[[Type]] monstersKoa'ki Meiru Doom]]", using other Types according to the Deck's main strategy. Often overlooked is the fact that you can use card-destroying "[[Iron Core Armor]]" to substitute for the maintenance cost of KoaKoa'ki Meiru monsters. The main advantage of including Ice]]" and "[[Iron Core ArmorKoa'ki Meiru Tornado]]" in your Deck is that there exists plenty , and the mass effect negation of support for [[Equip Spell Card]]s. For example, using "[[Hidden ArmoryKoa'ki Meiru Hydro Barrier]]" to search for . While "[[Iron Core Armor]]" from your Deck or Graveyard may cause you to have one Koaof Koa'ki Meiru monster sent to your Graveyard, which could be used " is central to fuel the effect of "[[Koaarchetype'ki Meiru Ghoulungulate]]"s playstyle, and there are multiple dedicated searchers for it (e.g. "[[Trade-InCore Transport Unit]]" can work well if you are using "[[Beast King Barbaros]]" to reveal ), the fact that the card doesn't have any effects itself and is purely an enabler for certain specific cards means that more modern "[[Koa'ki Meiru Urnight]]" will typically try to downplay its importance, in favor of other external enablers (and "maintenance cost providers) like "[[Koa'ki Meiru CrusaderAdamancipator]]"monsters. Other level 8 monsters to work with "[[Trade-In]]" are "[[Koa'ki Meiru Valafar]]" and "[[Koa'ki Meiru Maximus]]". Maximus can also be revealed for "[[Koa'ki Meiru Drago]]" and Valafar is a strong beatstick that is immune to "[[Torrential Tribute]]", "[[Bottomless Trap Hole]]", "[[Mirror Force]]", "[[Call of the Haunted]]", and "[[Core Reinforcement]]". It would be wise to include cards that return monsters and other cards to your or your opponent's hand. For example, "[[Compulsory Evacuation Device]]" or "[[Penguin Soldier]]" can both remove threats from the field or keep a Koa'ki Meiru alive for a turn or even using it for the maintenance.  Usual Anti-Meta tricks like "[[Grave of the Super Ancient Organism]]" or "[[Royal Oppression]]" work fairly well, since Koa'ki Meirus can mantian 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. * "[[Koa'ki Meiru Urnight]]" and "[[Koa'ki Meiru Crusader]]" are [[Beast-Warrior]]-type monsters and have the same 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. Wall, Sandman, and Guardian all have effect negation abilities: they are used for a Rock Stun deck. Boulder and Prototype are both extremely useful for Koa'ki Meiru monsters because they do not require the normal sacrifice-Boulder is used to search for other Koa'Ki Meiru monsters or Iron Cores, while Prototype can sacrifice itself to prevent a Koa'ki Meiru monster from being destroyed during the end phase of the turn. * "[[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 in a different 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 easily achieved 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 the 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]]* [[Koa'ki Meiru Prototype]]* [[Fossil Dyna Pachycephalo]] [[Beast-Warrior]] (For [[Koa'ki Meiru Crusader]]/[[Koa'ki Meiru Urnight]])* [[Beast King Barbaros]]* [[Chiron the Mage]]* [[Pitch-Black Warwolf]]* [[Reborn Tengu]]* [[T.G.

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 "[Stardust Dragon[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 "[[Number 39: UtopiaTrap 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. "[[Steelswarm RoachSolemn Warning]]", "[[Solemn Judgment]]", "[[Archlord Kristya]]", "[[Vanity's Fiend]]" or "[[Vanity's Emptiness]]" are all effective against the deck.{{Archseries navbox}}{{ArchetypeNavboxArchseries navbox (Duel Links)}}[[Category:Archetypes]][[Category:Deck TypeTCG and OCG archetypes]]
