 "'''Mermail'''" ({{Ruby|水精鱗|マーメイル}} ''Māmeiru'') is an [[archetype]] of [[WATER]]-[[Attribute]] and [[Aqua]], [[Fish]] and [[Sea Serpent]]-[[Type]] [[Monster Card|monsters]], used by [[Brooke Walker]] in the past, introduced in the ''[[Abyss Rising]]''. They These monsters are based on [[wikipedia:Mermaid|mermaids]] outfitted with armor, hence "mail". They are intimately related to the "[[Abyss-]]" archetype, as they all belong to the archetype. The [[Level ]] 3 "Mermail" monsters are all Aqua-Type [[List of female cards|female]] monsters, Level 4 "Mermail" monsters are all Fish-Type male monsters, and Level 7 "Mermail" monsters are all Sea Serpent-Type monsters, except for the Aqua "[[Mermail AbyssteusAbyssbalaen]]" and "[[Mermail AbyssbalaenAbyssteus]]", which are Aqua-Type monsters.==Design==Each "Mermail" monster is based on a real life aquatic animal. The original three female Level 3 "Mermail" monsters released in ''Abyss Rising'', "[[Mermail Abysslinde]]", "[[Mermail Abyssgunde]]" , and "[[Mermail Abysshilde]]", have names coming from the Rhinemaidens (Woglinde, Wellgunde, Flosshilde) in the German opera ''[[wikipedia:Der Ring des Nibelungen|Der Ring des Nibelungen]] (The Ring of the Nibelung)'' by [[wikipedia:Richard Wagner|Richard Wagner]]. The Level 7 "Mermail" monsters (excluding "[[Mermail Abyssbalaen]])", "[[Mermail Abyssmegalo]]", "[[Mermail Abyssleed]]" and "[[Mermail Abyssteus]]" take inspiration from [[wikipedia:extinct species|extinct aquatic species]]. The Xyz Monsters, "[[Mermail Abyssgaios]]" and "[[Mermail Abysstrite]]" take inspiration from [[wikipedia:Twelve Olympians|Ancient Greek deities]].===[[Main Deck]] members==={| class="wikitablesortable"! scope="col" | Mermail ! scope="col" | [[Level]]!scope="col" | [[Type]]!

The "Mermail" archetype focuses on discarding or tributing WATER monsters to Special Summon "Mermail" monsters and activate their effects, and triggering additional effects off of these discards or tributes to generate advantage. They secondarily focus on interacting with the "[[Abyss-]]" archetype of Spell/Trap cards to support their strategy.Most [[Level]] 3 "Mermail" monsters all share a (excluding "[[Mermail Abyssdine|Abyssdine]]" and "[[Mermail Abyssocea|Abyssocea]]") have similar [[Card effect|effectTrigger Effect]] s that are triggered when they get are [[send|sent]] to the [[Graveyard]] , which usually Special Summons another "Mermail". {| class="wikitable mw-collapsible autocollapse"! colspan = 3 | Level 3 Mermail Summary|- they !

They have a small relation to the The Level 7 "UmiMermail" series since one of their support cards, monsters each share two effects with a common effect pattern.{{Quote|#''"You can discard [[Abyss-stromDiscard Cost]]", uses "Umi" for its effectto the GY; Special Summon this card from your hand. This is also evident in the new When Summoned this way: You can [[Field SpellEffect 1]] introduced in their debut set of "''[[Abyss Rising]]#'' (which, name wise, partially refers to them as well) whose effect treats it as "Umi." The Field Spell, "You can Tribute [[Lemuria, the Forgotten CityTribute Cost]]", helps them Xyz for a higher ; [[RankEffect 2]] [[Xyz Monsters]], and partially supports the Summoning of "Abyssgaios". Combining ''}}These effects will further trigger the original Level 3 "UmiMermail" cards with these newer cards is not a good option since there are much better options available for this task which outclass monsters' effects, and can also trigger some the "Umi" cards. The "Umi" cards ones that only have 1 connection in which they function properly, and their effects are generally weaker than those of trigger when sent from the "Mermail". Another possibility for a field spell is "[[Clear World]]". It causes the user of a water monster to discard at the end of their phase, facilitating their effects while possibly hindering the other playerGY via Tributing.

Swarming and Xyz Summon are thus their main style of play, and with all the recent support for WATER{| class="wikitable mw-collapsible autocollapse"! colspan = 5 | Level 7 Mermail Summary|-! rowspan = 2 | Mermail !! colspan = 2 | Effect 1 Details !! colspan = 2 | Effect 2 Details|-attribute !

Another strategy is to lock the attacks and effects The boss monster of strong opponent monsters with "Abyssgaios", using his effect to negate the effect of face-up enemy monstersarchetype, as his effect can be activated in any player's turn. To Summon him, one can Special Summon "Abyssmegalo's" effect, and then adding "[[Abyss-sphereMermail Abyssgaios]]" to your hand, letting you Summon another "Abyssmegalo" in your next turn. This is a Rank 7 Xyz monster that can also be done with "[[Mermail Abysslinde]]'s" effect to Summon "Abyssmegalo" prevent Level 5 or higher monsters from your Deck. Using the effect of "Lemuria" attacking, and negate the swarming power effects of "Mermails" can help as well, needing 3 face-up Level 4 "Mermails" or 4 face-up Level 3 "Mermails"opposing monsters with less ATK than it.

The "AbysslindeMermail" archetype supports, and is supported by, the "[[Abyss-]]" archetype of Spell/Traps. The "Abyss-" Traps provide some temporary power boosts or temporary Special Summons of "Mermail" monsters. The "Abyss-" Spells meanwhile are far more interesting: all the "Abyss-" Spells, the "Abyss-scale", are [[Equip Spell]]s that can only be equipped to "Mermail" monsters, and both boost the equipped monster's attack and provide 1 [[Negate|negation]] to an opponent's effect; "[[Abyss-scale of the Kraken|Kraken]]" negates a Monster, "[[Abyss-scale of the Mizuchi|Mizuchi]]" negates a Spell, and "[[Abyss-scale of Cetus|Cetus]]" negates a Trap. These negations are ''mandatorily'' applied to the first applicable effect they face, and they will immediately send themselves to the GY after negating one of effect. Despite these drawbacks, the "Abyss-scale" cards are still searchable negates can significantly disrupt the Deckopponent's most important plays.The main "Mermail" playstyle thus involves swarming "Mermail" monsters with Special Summoning cardseffects, gaining advantage off of their own discards and tributes, and ultimately either beatdown the opponent by summoning several Level 7 beaters or controlling the field with "Abyssgaios" and the "Abyss-scale" Spells. It acts as a "[[Mother GrizzlyMermail Abyssmegalo|Abyssmegalo]]" is thus vitally important for each of the three components of this strategy; it is a Level 7 beatstick that can Special Summon itself, discard other "Mermail" monsters, and search "MermailsAbyss-" that also works upon being destroyed by card effectsSpell/Traps.

The "MermailsAbyss-" also go hand-in-hand with the trap card "[[AtlanteanAbyss-strom]]" connects the archetype since their effects are activated when sent to the graveyard to activate a WATER monsters effect. By discarding "[[Atlantean Heavy InfantryUmi (series)|Umi]]", "series of [[Atlantean MarksmanField Spell]]" or "[[Atlantean Dragoons]]"s, to activate and the archetype does thematically have its own "Mermailsarchetypal Umi" effects you can destroy a card on in the field ("Heavy Infantry" and form of "Marksman") or search your Deck for any [[Sea SerpentLemuria, the Forgotten City]]-Type monster ("Dragoons. Though "Lemuria"), such as is generic and does not specifically support "AbyssmegaloMermail", while also gaining it does support the "Mermail's" effectsplaystyle of swarming monsters and making Xyz plays, enabling Xyz Monsters of other Ranks to be made.

== Story =={{See also|[[Gagaga Academy Tospedia card storylines#"The Mermails and Atlanteans" Edition|Gagaga Academy Tospedia card storylines]]}}The Mermail"Mermails" used to peacefully live in their underwater city, archetype synergizes especially well with the "[[Lemuria, the Forgotten City|LemuriaAtlantean]]"archetype, and albeit good in since their effects are activated when sent to the arts of fighting, they would rarely use this abilitygraveyard to activate a WATER monsters effect. However, sudden changes in the earth's crust made By discarding "Lemuria[[Atlantean Heavy Infantry]]" rise above the ocean, leaving the "Mermails" homeless. In that moment, the Emperor of the "[[AtlanteanMarksman]]" army, or "[[Poseidra, the Atlantean Dragon|PoseidraDragoons]]", choose to let activate the "Mermails" live under his protection, but they would have to obey his orders. Using the great treasure of effects you can destroy a card on the field ("Heavy Infantry" and "MermailsMarksman", the ) or search your Deck for any [[Abyss-squall|Golden RingSea Serpent]]monster ("Dragoons"), to control the weather, such as "PoseidraAbyssmegalo" ordered an all-out attack against their archenemies, while also gaining the "[[Fire King]]sMermail". Unfortunately, “Poseidra’s” body was taken over by [[Mermail Abyssgaios|the king]] residing in the Ring. The king eliminated the “Atlantean” army with ease. It appears that “Abysstrite” sealed the Ring away because the advent of the king required a sacrificeeffects.

===Weaknesses===* Cards that prevent searching or Special Summoning from the Deck, such as "[[Thunder King Rai-Oh]]" and , "[[Mistake]]" severely , or "[[Deck Lockdown]]", slows down this Deck theme the archetype significantly, as it halts all of the archetype requires significant searching effects to make combo plays and maintain their grind game.* Cards that negate card effect activations in the GY, such as "[[Debunk]]", "[[Silent Graveyard]]", "[[Necrovalley]]", "[[The End of Anubis]]"Mermail, or " monsters while also being a higher ATK than most [[Soul Drain]]", halts many of them the key GY monster effects the archetype.* Cards that banish cards sent to the GY, such as well. "[[Deck LockdownMacro Cosmos]]" and "[[Dimensional Fissure]]" , also works and stops Special Summoning prevents the archetype from activating their GY effects. It can also prevent "[[Moulinglacia the Main Deck too, but can be more easily countered so it is more useful as an early disruption tactic and Elemental Lord]]" from being Summoned.* The archetype's need for Tributediscarding-themed and/or Synchro/XYZ monster focused Decks Tributing-friendly monsters means that have no need it struggles to Special Summon from the Main Deck at allmaintain its grind game if built or played poorly.

"[[Debunk]]", "[[Forbidden Graveyard]]", "[[Necrovalley]]", "[[The End of Anubis]]" and "[[Soul Drain]]" also halts many of the key monster effects of a "Mermail" Deck as well to slow it down, but it does not affect the [[Xyz Summon]] options available unlike "Thunder King Rai-Oh". "[[Skill Drain]]" also affects the speed of this Deck and can assist in slowing it down too, but without "Debunk" or "Soul Drain" (or other similar Graveyard negation effect cards) their Graveyard activating effects are not affected and can result in its destruction.==Notes== [[Banish]] effect cards can cause havoc on "Mermail" and "Mermail"/"Abyss-" Decks because they lose their Graveyard activating effects, so "[[Macro Cosmos]]" and "[[Dimensional Fissure]]" are worth consideration. It also can prevent "[[Moulinglacia the Elemental Lord]]" from being Summoned through a lack of WATER monsters in the Graveyard. "[[Bottomless Trap Hole]]" is also a good option for removing dangerous support, such as "Moulinglacia", "[[Mermail Abyssmegalo]]" and "[[Mermail Abysslinde]]". And while "[[King Tiger Wanghu]]" can disrupt a "Mermail" or "Mermail"/"Abyss-" Deck, its continuous destruction effect will trigger their own effects normally, so cautious use is required: "[[Fossil Dyna Pachycephalo]]" the "Vanity's" monsters, "[[Vanity's Emptiness]]" and "[[Jowgen the Spiritualist]]" may be a more effective option in countering "Mermails". One major problem a "Mermail" user might face is "over-extending". Because so many "Mermail" effects rely on discarding or being discarded, a Duelist using the archetype might spend all but a couple of cards in their hand on swarming the field with monsters. Despite the many searchers of the archetype, a player might exhaust all of the options they built with a large hand and fall victim to a well-timed "[[Gorz the Emissary of Darkness]]".{{notelist}}
