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 of sending an Iron words "Core to the grave or revealing a monster of the same type" and "Chimera"). There are exceptions such as that of [[==Design==The "Koa'ki Meiru Powerhand]]" archetype consists of a plethora of different creatures, featuring elementals, dragons, where you must reveal a [[Normal Trap Cards|Normal Trap Card]]statues, warriors and many more and can overall be described as a mishmash of art styles. KoaThey don'ki Meirus are all [[EARTH]], [[WIND]], [[WATER]] t really have any connection in design or color, 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 Meiru" is a [[FIRE]] attributes, rendering them immune to their own control based effects which often affect [[LIGHTstun]] and /[[DARKcontrol]] monsters. All of the "KoaDeck revolving around fulfilling its monsters'ki Meiru" have [[maintenance cost]]s in order to keep them on the same mark (3 dragons) on some part of their body or on a weapon they havefield and apply their field-controlling effects. AlsoSecondarily, many Koa'ki Meiru and related cards' artwork uses yellow, orange, and red, except the archetype revolves around interactions with the Normal Spell "[[Iron Core of Koa'ki Meiru Ghoulungulate]]". ==Playing Style==The theme was initially designed to bring down the dominating decks Almost every "Koa'ki Meiru" monster has a maintenance cost that must be performed during each of over 2 banlists therefore centering around heavy control elements. Seeing as the meta was player''completely'' dominated by s [[LIGHTEnd Phase]] and DARK deckss, effects specifically targeted both Attributes therefore bringing about a specific Meta, Anti Meta themeotherwise they will destroy themselves. Because of their high [[ATK]], 11 Level 4 monsters from 1900 ATK, topping out at 3000 ([["Koa'ki Meiru Valafar]]), and the nature " monsters typically have a choice of two actions for their maintenance costs; the new support, options are typically sending an "Iron Core" from the theme has taken a more aggressive approach with powerful beatdown elementsplayer's hand to the Graveyard, namely [[Koaor revealing a card in the player'ki Meiru Rooklord]] and [[s hand (typically a monster of their same type).{| class="wikitable mw-collapsible autocollapse" style="margin-left: auto; margin-right: auto; border: none; text-align: center" |+ {{nowrap|Koa'ki Meiru Urnight]].Monsters & Maintenance Costs}} Generally speaking, there are two ways to use ! rowspan = 2 | Koa'ki Meiru cards.

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 KoaSea Panther|Sea Panther]] || 4 || WATER || Sea Serpent| Reveal 1 WATER monster|-| [[Koa'ki Meiru Powerhands only require War Arms|War Arms]] || 4 || EARTH || Warrior| Reveal 1 Normal Trap Card revealed).

Most A number of the "Koa'ki Meiru" monsters are used against (e.g. "[[Effect Monsters]], mostly [[DARKKoa'ki Meiru Drago|Drago]] " and "[[LIGHTKoa'ki Meiru Doom|Doom]] monsters, since they are the commonly used decks (") have effects focused on countering [[InfernitiesLIGHT]], and [[LightswornsDARK]], [[Blackwings]] etc.monsters (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]]-", "[[TypeKoa'ki Meiru Guardian|Guardian]] and ", "[[Beast-WarriorKoa'ki Meiru Sandman|Sandman]]", "[[Koa'ki Meiru Wall|Wall]]") also form a thematic sub-series with a single effect pattern: each of them can [[Typenegate]] monsters, using other Types according to the deckan opponent's main strategyaction (summoning a monster or activating a card/effect of a card type) by tributing themselves. Often overlooked is the fact that you can use "[[Iron Core Armor]]" to substitute for the maintenance cost of KoaKoa'ki Meiru monsters. The main advantage of including "[[Iron Core Armor]]" cards can be played as staples in your deck is that there exists plenty of support for [[Equip Spell Cards]]other Typing-focused Decks, or played as a single dedicated Deck. For example, using As a dedicated "[[Hidden Armory]]Koa'ki Meiru" to search for "[[Iron Core Armor]]Deck, the Deck primarily focuses on the Level 4 EARTH Rock " from your deck or graveyard may cause you to have one Koa'ki Meiru monster sent " monsters due to your graveyardtheir accessibility, power, which could be used to fuel and synergy with [[Rock]] support; they form a part of the effect of popular "[[Koa'ki Meiru GhoulungulateRock Stun]]"Deck. The Deck's main searchers are "[[Trade-InDiamond Core of Koa'ki Meiru]] can work well if using [[Beast King Barbaros]] to reveal for ", "[[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 [[low-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 TributeKoa'ki Meiru Doom]]", the card-destroying "[[Bottomless Trap HoleKoa'ki Meiru Ice]], " and "[[Mirror Force]], [[Call of the HauntedKoa'ki Meiru Tornado]]", and the mass effect negation of "[[Core ReinforcementKoa'ki Meiru Hydro Barrier]]". It would be wise to include cards that return monsters While "Iron Core of Koa'ki Meiru" is central to 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 Koafact that the card doesn'ki Meiru alive for a turnt have any effects itself and is purely an enabler for certain specific cards means that more modern "Koa'ki Meiru" 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" monsters. ===Recommended cards===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 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]])* [[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]]
