Numerous water decks rely on this the Field Spell Card "[[A Legendary Ocean]]" to perform powerful effects as discussed below.

====Daedalus Methodmethod==== One way to use "[[A Legendary Ocean]] " is with the "[[Levia-Dragon - Daedalus]] " or its superior, the "[[Ocean Dragon Lord - Neo-Daedalus]]". Both monsters' effects require [[A Legendary Ocean]] or "[[Umi]] " to be activatedon the field (which "A Legendary Ocean" is treated as). As a result, the entire field is destroyed except the "Daedalus", leaving the user a clear field to perform direct attacks on the opponent. If "[[Abyssal Kingshark]] " is on the field when you activate the effect of "Daedalus' effect", the Shark "Kingshark" is not destroyed. Normally, people would prefer [["A Legendary Ocean]] " for this operation in contrast to [["Umi]]. This is ", because summoning the Summoning "[[Levia-Dragon - Daedalus]] " would only require one [[Tribute]]. Others prefer to use the card "[[Big Wave Small Wave]] " to summon the Summon "Daedalus", which is a smart addition to Water WATER Decks regarding using these tactics. Another good idea is using "[[Warrior of Atlantis]] " to search out [["A Legendary Ocean]] or [[Umi]]".

====Decrease Monster Level Method method 1==== Another way to use "[[A Legendary Ocean]] " is to utilize its level Level decreasing ability effect on water WATER monsters on the field and in the hand. Strong Level 5 water WATER monsters such as "[[Giga Gagagigo]]", "[[Terrorking Salmon]]", or "[[Catapult Turtle]] " can then be normal summoned Normal Summoned without [[Tribute]], allowing the user a more efficient way of bringing out monsters to inflict heavy damage.

====Decrease Monster Level Method method 2==== Another variation of this method utilizes stall cards such as "[[Gravity Bind]] " or "[[Level Limit - Area B]] " to halt monsters above Level 4. Since the user's water WATER monsters (preferably monsters originally Level 4) are decreased in levelLevel, then those monsters would be able to escape the stall cards. This allows "[[Mermaid Knight]] " or "[[Amphibious Bugroth MK-3]] " to either attack twice or attack directly. In the case of the "Bugroth", "[[Limiter Removal]] " can prove as a useful card. "[[Field Barrier]] " will help in protecting "[[A Legendary Ocean]]". Spell and/or trap Trap negation and/or removal will be handy as well , including "[[Dust Tornado]]", "[[Twin Twisters]]"/"[[Mystical Space Typhoon]]", or "[[Solemn Judgment]]".

[["A Legendary Ocean Deck]]s " Decks to some extent could can also utilize synchro monsters[[Synchro Monster]]s. One of the latest support cards is "[[Deep Sea Diva]]. Not only " is this card a [[Tunermonster]], but and when [[Normal Summon]]ed, it can bring out a Level 3 [[Sea Serpent]] -[[Type]] monster from your [[Deck]]. Three examples would be , such as "[[Atlantean Pikeman]]", "[[Mermaid Archer]]", and or "[[Spined Gillman]]". This could either bring about can allow a Level 4 or a Level 5 [[Synchro Monster]] to be Summoned easily, unless a Level 2 or Level 3 [[Synchro Monster]] comes out. This should be used as a back up plan because [[although with "A Legendary Ocean]] " it will downgrade these [[Water]] [[Monster]]'s level making it more difficult to [[Summon]] instead allow the desired [[Synchro Monster]]. However, it is possible to also utilize this [[Field Spell Card]] to bring out the necessary [[Summoning of lower-Level Synchro Monster]]Monsters. In addition to thatAdditionally, "[[Deep Sea Diva]] " has less than 1500 [[ATK]] , so it can be added back to your [[Handhand]] by "[[Salvage]]. However, [[Water]] Deck users must be aware of its low attack. A [[Monster]] with 200 [[ATK]] and 400 [[DEF]] cannot survive for very long. All in all, using these can be a great advantage since it can gives the user more options in a [[Duel]]".

"A Legendary Ocean " Decks to some extent could can also utilize [[Xyz monstersMonster]]s.Due to "A Legendary Ocean" lowering the lowering Levels of water WATER monsters Levels, it would be is easy to get out a Summon [[rankRank]] 3 or lower Xyz monsters, specificallyMonsters, particularly WATER Xyz monstersMonsters. Also, using original Level 5 water WATER monsterswhose Levels are lowered by "[[A Legendary Ocean]]", such as "[[Giga Gagagigo]] " or "[[Terrorking Salmon]]", whose Levels are lowered by [[A Legendary Ocean]], can summon out strong allows the player to Summon Rank 4 Xyz monstersMonsters, such as "[[Bahamut Shark]] who " which can use his its effect to summon out Summon strong Rank 3 or lower water WATER Xyz monsters who get boosted attack from [[A Legendary Ocean]]Monsters.
