Shark ( archetype ) " Shark " ( シャーク " Shāku " ) is an archetype used by Reginald Kastle / Nash in the " Yu - Gi - Oh ! ZEXAL " anime and manga . Most of them are Level 3 or 4 WATER - Attribute and / or Fish - Type . Many have swarm effects , allowing easy Summoning of Rank 3 - 5 monsters . They are only support ed as an archetype in the anime and manga . Playing style . " Shark " monsters ( except for " Scrap Shark " , " Shark Fortress " and " Corroding Shark " ) are all WATER . " Xyz Remora " can almost instantaneously summon " Number 32 : Shark Drake " . A few of these monsters , notably " Metabo - Shark " and " Scrap Shark " , sport decent to high ATK at low Level s , allowing them to start out as beaters when Summoned . This lets them battle outside the Extra Deck . Their effects , as mentioned , allow them to manipulate their Levels between 3 and 5 , allowing them to Summon Rank 3 to 5 Xyz Monster s quite easily . Seeing as this archetype is built for aggression and swarming , a fast - paced Deck can be built using " Shark Stickers " , " Shark Cruiser " ( although this card takes a bit more prediction and a lot more luck ) , and most notably " Hammer Shark " to swarm the field . It is actually quite easy to pull combos with this Deck . The most basic one is to Normal Summon " Hammer Shark " , using its effect to Special Summon any Level 3 or lower WATER monster , then Special Summoning " Shark Stickers " . " Double - Fin Shark " is an excellent card to make an instant Rank 4 Xyz ( though only WATER ) . Another rather potent combo is to use the effect of " Bahamut Shark " to Special Summon " Number 47 : Nightmare Shark " which can attach another Shark monster like " Shark Stickers " to itself despite being Summoned with no Xyz Materials , and thus gain its rather useful effect too . Since this Deck focuses on swarming the field and being aggressive , cards like " Sea Lord ' s Amulet " can prevent your WATER monsters from being destroyed by your opponents card effects . Another good combo to maintain field presence is to use the effect of " Bahamut Shark " to Special Summon a Rank 3 WATER Xyz monster and then Xyz Summon again to summon " Full Armored Black Ray Lancer " and activate " Sea Lord ' s Amulet " to prevent " Full Armored Black Ray Lancer " from being destroyed and let " Full Armored Black Ray Lancer " attack your opponent ' s monsters to destroy his Spell / Trap cards . One should remember that the effect of " Bahamut Shark " only applies to " the rest of the turn " when restricting its attack . " Saber Shark " can help easily to Summon Rank 5 Xyz monsters like " " and " , " if one needs to defeat more powerful monsters , while another option is " Shark Fortress , " which protects your own monsters and can allow any monster to attack twice during the Battle Phase . " Metabo - Shark " is good due to its effect of bringing back two fish monsters from the graveyard and adding them to your Deck . One in - Deck " boss monster " , introduced in Cosmo Blazer , is " Hyper - Ancient Shark Megalodon " who sports the highest original ATK in the entire archetype ( 2900 ) . Its effect destroy s a monster when it inflicts Battle Damage , further pushing the aggressiveness of the archetype . The true boss monster is seen to be " " whose effect drops an monster ' s ATK and DEF to 0 , while " Number 32 : Shark Drake " brings a monster back that it destroyed by battle and lowers its ATK by 1000 , while also allowing it to attack again . " " is also useful due to its effect that allows a WATER monster to attack directly , allowing both a large amount of damage , and the triggering of " Megalodon ' s " effect . As such , this archetype can be used very aggressively to beat the opponent down . Another technique to summon " Number C32 : Shark Drake Veiss , " is by using a " Rank - Up - Magic " Spell card on " Number 47 : Nightmare Shark , " rather than using " Shark Drake " as Xyz Material . Though not Shark monsters themselves , " " is an excellent addition for cheap monster removal , with its evolved form being able to be teched in as well , " . " Most " Shark " monsters ' effects activate only when they are Normal Summoned , so to fully utilize them , you can tech in " Double Summon " or " Ultimate Offering " ( though the latter is now Forbidden ) to trigger these effects . By doing this , you can Tribute Summon " Hyper - Ancient Shark Megalodon " more easily . " Water Hazard " can be excellent , as the deck can already swarm quite quickly , and can essentially cut down on a turn for Xyz Summoning , as well as expanding your options if you don ' t have either " Hammer Shark " or " Shark Stickers " in your hand .
