Water Deck

Utilizing A Legendary Ocean Methods
Numerous water decks rely on this field spell card to perform powerful effects as discussed below.


 * Daedalus Method: 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 activated. As a result, the entire field is destroyed except the Daedalus, leaving the user a clear field to perform direct attacks on the opponent. Normally, people would prefer A Legendary Ocean for this operation in contrast to Umi. This is because summoning the Levia-Dragon - Daedalus would only require one Tribute. Others prefer to use the card Big Wave Small Wave to summon the Daedalus, which is a smart addition to Water Decks regarding these tactics. This method is preferably combo with the Stall Method to protect yourself when you aren't able to draw Daedalus or unable to summon it yet.With this approach, the best thing to do is swarm the field and then activate Aegis of the Ocean Dragon Lord to protect the monsters on your field, use daedalus's ability and destroy the field (except for your monsters), and you should have a field of monsters left to go for a direct attack and an instant win.


 * Stall Method This could be considered "Decrease Monster Level Method 3", but this specifically focuses on stalling. By utilizing the abilities of Gravity Bind, Level Limit - Area B, A Legendary Ocean, and Final Countdown, you can attack with all level 4 water monsters (since their Level is lower by 1 because of A Legendary Ocean effect if it's on the field), force all level 4 and above monsters into defense, and put a time limit on the opponent's moves.

Utilizing Beatdown Methods
Water monsters can also be played to destroy monsters, spells, and/or traps to perform multiple direct attacks. In this case, A Legendary Ocean does not serve as big of a role whereas cards like Umiiruka may help a little more since it adds more significant ATK strength.


 * Orca Method: This variation focuses on the cards Orca Mega-Fortress of Darkness along with its "ammo" cards: Cannonball Spear Shellfish and Torpedo Fish. Both of these "ammo" cards are tributed to destroy either a monster or a spell/trap, giving this method a very versatile edge. Since these will be sent to the Graveyard frequently, it is wise to add in Pot of Avarice and Salvage to retrieve "ammo." Umi / A Legendary Ocean or Umiiruka prove handy in increasing ATK strength as well. A Legendary Ocean can also be used to escape the Orca's tribute requirement.


 * Abyss Soldier and Penguin Soldier Method: This method uses Abyss Soldier and Penguin Soldier to send cards back to the opponents hand and then allowing you to attack directly. Keep in mind that Gale Lizard also sends any monster to your opponent's hand. Combined with A legendary Ocean Gale Lizard has 1600 attack and can easily be powered up. Abyss Soldier is a powerful monster on his own with 1800 attack while A Legendary Ocean is on the field. Combine this method with swarming tactics like Aqua Spirit's effect or Mermaid Knight's double attack effect to hit for massive damage in one turn while attempting to shut down any chance of your opponent getting out powerful monsters.


 * Hydrogeddon: If your opponent is simply summoning defense position monsters to try to stall until they get better cards then you can pretty much wipe out their entire side with Hydrogeddon. 1800 attack (assuming you have A Legendary Ocean on the field) beats the defense of most of the common monsters out there, and when you do destroy a monster you can special summon another Hydrogeddon.


 * Deep Sea Diva Swarm: If you want to increase the attack of your monsters easily, or just want to get a low level monster with a good amount of attack points, use Deep Sea Diva to special summon a level 3 or lower sea serpent type monster out on the field. The two key cards are Mermaid Archer which you can equip Deep Sea Diva to to raise it's attack, or you can special summon Spined Gillman which raises the attack of all: Sea serpent, aqua, and fish types you control by 400 points.  It is also a good idea to have Star Boy which also raises the attack of all water monsters on the field and lower any fire monsters. This strategy works well if you have Double Summon so you can lay out more Deep sea Divas and swarm you opponent with low leveled, high attack point monsters.  This can work well with Gravity Bind or Level Limit - Area B to keep your opponents monsters grounded while you increase your attack and avoid the stall effects.  If you run low level synchro cards, Deep Sea Diva is a tuner that that can easily help you get what you need.
