The strongest " is a combination of the monsters require a maintenance cost in the form words "Core", "Chimera" and "Mail", sometimes romanized as "Core Chimair" (a combination of sending an Iron Core to the grave or revealing words "Core" and "Chimera").==Design==The "Koa'ki Meiru" archetype consists of 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 are all [[EARTH]], [[WIND]], [[WATER]] " have the same mark (3 dragons) on some part of their body or on a weapon they use.==Playing style=="Koa'ki Meiru" is a [[[FIREstun]] attributes, rendering them immune to their own /[[control based effects which often affect [[LIGHT]] and ] Deck revolving around fulfilling its monsters' [[DARKmaintenance cost]] monsters. All of s in order to keep them on the "field and apply their field-controlling effects. Secondarily, the archetype revolves around interactions with the Normal Spell "[[Iron Core of Koa'ki Meiru]]" have the same mark (3 dragons) on some part of their body or on a weapon they have. Also, many Koa.Almost every "Koa'ki Meiru and related cards' artwork uses yellow, orange, and red, except " monster has a maintenance cost that must be performed during each of the player's [[End Phase]]s, otherwise they will destroy themselves. "Koa'ki Meiru Ghoulungulate]]. ==Playing Style==The theme was initially designed to bring down the dominating decks " monsters typically have a choice of over 2 banlists therefore centering around heavy control elements. Seeing as two actions for their maintenance costs; the meta was ''completelyoptions are typically sending an "Iron Core" from the player'' dominated by [[LIGHT]] and DARK deckss hand to the Graveyard, effects specifically targeted both Attributes therefore bringing about or revealing a specific Meta, Anti Meta theme. Because card in the player's hand (typically a monster of their high [[ATK]], 11 Level 4 monsters from 1900 ATK, topping out at 3000 ([[Koa'ki Meiru Valafar]]same type), and the nature of the new support, the theme has taken a more aggressive approach with powerful beatdown elements, namely [[.{| class="wikitable mw-collapsible autocollapse" style="margin-left: auto; margin-right: auto; border: none; text-align: center" |+ {{nowrap|Koa'ki Meiru Rooklord]] and [[Monsters & Maintenance Costs}}! rowspan = 2 | Koa'ki Meiru Urnight]]. Generally speaking, there are two ways to use Koa'ki Meiru cards. The most obvious is to simply use a dedicated deck; the other being to use individual ! rowspan = 2 | Level! rowspan = 2 | Attribute! rowspan = 2 | Type! colspan = 2 | Maintenance Cost|-! Option 1! Option 2|-| [[Koa'ki Meiru monsters as a supplement to Type specific decks of their type, giving an [[Anti-MetaMaximus|Maximus]], controlling aspect to it as well asbeing able to maintain it through the alternative maintenance cost; for example, using [[|| 8 || WIND || Dragon| rowspan = 20 | Send 1 "Iron Core"| Send 1 "Koa'ki Meiru Drago]] in a Dragon type deck as seen in Disaster Dragon builds." monster|- 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 MeiruValafar|Valafar]] from your deck and graveyard such as || 8 || FIRE || Fiend| —|-| [[Koa'ki Meiru BoulderRooklord|Rooklord]], [[|| 7 || EARTH || Warrior| Reveal 1 Warrior monster|-| [[Koa'ki Meiru CrusaderGhoulungulate|Ghoulungulate]], and [[Core Transport Unit]]. || 5 || EARTH || Zombie| Reveal 1 Zombie monster|-| [[Iron Core Immediate DisposalKoa'ki Meiru Powerhand|Powerhand]] 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 || Machine| Reveal 1 Normal Trap|-| [[Koa'ki Meiru RooklordUrnight|RooklordUrnight]] and || 4 || EARTH || Beast-Warrior| Reveal 1 Beast-Warrior monster|-| [[Koa'ki Meiru DragoBergzak|DragoBergzak]].

With the addition of || 4 || EARTH || Insect| Reveal 1 Insect monster|-| [[Koa'ki Meiru UrnightCrusader|Crusader]] from [[Absolute Powerforce]], you gain a swarm/toolbox element. || 4 || EARTH || Beast-Warrior| Reveal 1 Beast-Warrior monster|-| [[Koa'ki Meiru GhoulungulateGravirose|Gravirose]] is nice protection but your tribute fodder is best used on Rooklord. S/t protection is a better option. || 4 || FIRE || Plant| Reveal 1 Plant monster|-You can also play a RFG | [[Koa'ki Meiru deck. Ghoulungulate can protect your monsters while setting you up for [[Return from the Different DimensionOverload|Overload]]. Milling elements are recommended to load your grave. The set up takes time so you can use Royal Oppression as you aren't in any rush. Cyber Valley is also a great asset to the deck.|| 4 || EARTH || Rock| Reveal 1 Rock monster|-==Weaknesses==Because | [[Iron Core of Koa'ki MeiruGuardian|Guardian]] may often be in the graveyard, it is vulnerable to cards that can remove it from play, such as || 4 || EARTH || Rock| Reveal 1 Rock monster|-| [[Gladiator Beast RetiariKoa'ki Meiru Sandman|Sandman]], and || 4 || EARTH || Rock| Reveal 1 Rock monster|-| [[Macro Cosmos]Koa'ki Meiru Wall|Wall]]. Also, having multiple || 4 || EARTH || Rock| Reveal 1 Rock monster|-| [[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 Ice|Ice]] || 4 || WATER || Aqua| Reveal 1 Continuous Spell|-| [[Koa'ki Meiru Powerhands only require 1 Normal Trap Card revealed).

Obviously, the most important card needed in the deck is "[[Iron Core of KoaKoa'ki MeiruBoulder|Boulder]]", so having three in your deck is a must. Most of the monsters are used against || 4 || EARTH || Rock|-| [[Effect MonstersKoa'ki Meiru Hydro Barrier|Hydro Barrier]]|| 3 || WATER || Aqua|}In gameplay, mostly [[DARK]] and [[LIGHT]] monsters, since they are the commonly used decks ([[Infernities]]"Koa'ki Meiru" monsters have a variety of effects, ranging from consistency support, battle, [[Lightsworns]]destruction, [[Blackwings]] etcor negation focused effects.). Most A number of "Koa'ki Meiru decks should focus on " monsters (e.g. "[[RockKoa'ki Meiru Drago|Drago]]-" and "[[TypeKoa'ki Meiru Doom|Doom]] and [") have effects focused on countering [[Beast-WarriorLIGHT]]-and [[TypeDARK]] monsters, using other Types according to the deck's main strategy. Often overlooked is the fact that you can use (which were likely intended as "anti-meta" options against their contemporary LIGHT and DARK-based meta Decks).Four Level 4 EARTH Rock "Koa'ki Meiru" monsters ("[[Iron Core ArmorKoa'ki Meiru Overload|Overload]]" to substitute for the maintenance cost of , "[[Koa'ki Meiru monsters. The main advantage of including Guardian|Guardian]]", "[[Iron Core ArmorKoa'ki Meiru Sandman|Sandman]]" in your deck is that there exists plenty of support for [[Equip Spell Cards]]. For example, using "[[Hidden ArmoryKoa'ki Meiru Wall|Wall]]" to search for ") also form a thematic sub-series with a single effect pattern: each of them can [[Iron Core Armornegate]]" from your deck or graveyard may cause you to have one Koaan opponent'ki Meiru s action (summoning a monster sent to your graveyard, which could be used to fuel the or activating a card/effect of a card type) by tributing themselves."[[Koa'ki Meiru Ghoulungulate]]". [[Trade-In]] cards can work well if using [[Beast King Barbaros]] to reveal for [[be played as staples in other Typing-focused Decks, or played as a single dedicated Deck. As a dedicated "Koa'ki Meiru Urnight]] and [[" Deck, the Deck primarily focuses on the Level 4 EARTH Rock "Koa'ki Meiru Crusader]]. Other level 8 " monsters due to work their accessibility, power, and synergy with [[Trade-InRock]] are [support; they form a part of the popular "[[Rock Stun]]" Deck.The Deck's main searchers are "[[Diamond Core of Koa'ki Meiru Valafar]]", and "[[Koa'ki Meiru MaximusUrnight]]. Maximus can also reveal for ", and "[[Koa'ki Meiru DragoSupplier]] ". Aside from the "Rock Stun" "Koa'ki Meiru" monsters, other relevant high-power (and Valafar is a strong beatstick that is immune to low-cost) "Koa'ki Meiru" monsters include the LIGHT and DARK hard counters "[[Torrential TributeKoa'ki Meiru Drago]], " and "[[Bottomless Trap HoleKoa'ki Meiru Doom]]", the card-destroying "[[Mirror ForceKoa'ki Meiru Ice]], " and "[[Call of the HauntedKoa'ki Meiru Tornado]]", and the mass effect negation of "[[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 Device]] or [[Penguin SoldierCore Transport Unit]]"), for example, can both remove threats from the field or keep a 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 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 Organism]] or [[Royal OppressionAdamancipator]] works fairly well, since Koa'ki Meirus can mantain a solid game even without Special Summoning" monsters.  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]] share the [[Beast-Warrior]] type, and reveal requirement, while allowing for a good presence on the field and card advantage.  * [[Koa'ki Meiru Sandman]], [[Koa'ki Meiru Guardian]], [[Koa'ki Meiru Boulder]], [[Koa'ki Meiru Prototype]] and [[Gigantes]] can be extremely agressive 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. Even though you will be sending Iron Core of Koa'ki Meiru to your grave often it's not wise to include a [[Forced Requisition]] since it will only activate if you are '''DISCARDING''' a card. Since the text on [[Koa'ki Meiru powerhand]] state that either you need to reveal one normal trap or by '''SENDING AN IRON CORE OF KOA'KI MEIRU''' to your graveyard Forced Requisition will not activate so it will only hurt you if add it to your deck. ===Recommended Cards=== ====[[Monster Cards]]====[[Rock]](For [[Koa'ki Meiru Guardian]]/[[Koa'ki Meiru Sandman]])* [[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]])* [[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 "[[Trap 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 "[[Vanity's Emptiness]]" are all effective against the deck.{{Archseries navbox}}{{ArchetypeNavboxArchseries navbox (Duel Links)}}[[Category:ArchetypeTCG and OCG archetypes]]
