Players have been asking for new water support for a while now and Konami delivered with the latest box Abyssal Encounters which came with some interesting cards that were only added to the OCG last year. The most notable water support cards in this box are Warrior of Atlantis, Legendary Fisherman II, Citadel Whale, Abyss Soldier and of course Sea Stealth Attack.
Can be used when your Life Points are 1,000 or below. Until the End Phase, reduce the Level of all monsters in your hand by 3. This skill can be used to "Suijin, "Kazejin", and "Sanga of the Thunder," regardless of your remaining Life Points. This skill can only be used once per turn.
The strength of these decks come from the trap card Sea Stealth Attack, which has multiple effects. First of when you activate it you can activate one Umi from your hand or graveyard (which means you can activate A legendary Ocean since it’s always treated as Umi), Umi must be on the field for the following effects to be available. Next you have an effect that you can activate once per turn; you can banish one 1 water monster you control (this is a cost!) and for the rest of the turn your face-up spells/traps can’t be destroyed, at the end of that turn the banished monster is returned (same position as when it was banished). This is a very strong effect to dodge stuff like Enemy Controller, Wall of Disruption, Super Rush Headlong, Massivemorph,... (the list goes on and on).
It’s last effect makes it so that whenever one of you monsters, whose original level is 5 or higher (for example Legendary Fisherman II while Legendary Ocean is on the field meets this requirement), battles another monster, that monster is banished at the start of the damage step.
That last effect kinda works like a continuous Super Rush Headlong, however there are some important things to remember. First of if your opponent uses Super Rush Headlong; your monster will be destroyed. It doesn’t matter who the turn player is, the reason for this is that the effect of Sea Stealth Attack is a continuous effect, and Super Rush Headlong is an activated effect, so Sea Stealth Attack’s effect would activate only after Super Rush Headlong meaning it would be too late.
A very important thing to remember when playing this card, is to activate it as soon as possible (best thing to do is put your toggle button to ON and activate it during your opponent’s draw phase). The reason for this is that if you need to make use of its first effect, you can’t use it the moment you activate the trap, this is because the trap first needs to check if “Umi” is on the field.
If you are playing against this card, use backrow destruction first in case your opponent doesn’t know this and he won’t be able to protect his cards.
Another thing to remember when trying to deal with this card is to chain your backrow destruction to its first effect. For example if you use Enemy Controller on your opponent’s monster, and he uses its first effect to banish that Water monster, if you chain your backrow destruction (like Double Cyclone) your card will resolve first and the trap will be destroyed (because it wasn’t protected yet at that moment). If you would start out by using your Double Cyclone, your opponent could chain its first effect and their cards would be protected.
Mermail Abyssmegalo is an easy to summon high-leveled WATER monster, because of this he works well with Sea Stealth Attack. The summoning requirements for Abyssmegalo is discarding 2 WATER monsters which could be any monster in this deck and you would still get some utility out of the cost even when you discard another copy of Abyssmegalo to summon him. He will then search out your Abyss equip card which you can use on him for an attack boost and spell/trap disruption.
The last effect of Abyssmegalo is that he can attack twice during the battle phase by tributing another WATER monster you control. Again you can tribute almost any WATER monster in this deck and you will still find a way to use it later on. With 2 attacks and a great attack stat you can OTK your opponent or use those 2 attacks in combination with Sea Stealth Attack to clear your opponent's monsters.
Discarding is a big part of your strategy and therefore you need good discard fodder that will give you some added utility. Atlantean Marksman and Atlantean Heavy Infantry destroys cards on your opponent's field when discarded. Fishborg Planter can be revived by sending the top card from your deck to the graveyard and only if that card you send is a WATER monster. So after using Fishborg Planter as discard fodder you can use to possibly combo into the effect of the card you sent to the graveyard.
A Mermail Abyssmegalo you used as discard fodder can be revived from the graveyard by discarding 2 WATER monsters you control. Similarly a Citadel Whale you used as discard fodder can be revived by sending 2 WATER monsters on your field to the graveyard, additionally this special summoning will allow you to search Sea Stealth Attack.
The Atlantean monsters want to be sent to the graveyard so they can activate their effects, so aside from Abyssmegalo and Citadel Whale here are some more options to put them into the graveyard. Abyss Soldier discards a WATER monster to return a card on your opponent's field back to hand. With Atlantean's destruction effect this combo removes 2 cards from your opponent's field. Mermail Abysspike discards a WATER monster to search out a level 3 or lower WATER monster. Discard an Atlantean monster and search another to destroy a card while also keeping your resources up.
lots of decks in the current meta have are able to OTK their opponents, and these same decks are ones that heavy make use of special summoning. To avoid falling victim to an OTK Dragon Ice is a good tech option. When your opponent special summons a monster you can discard a card to special summon Dragon Ice from your hand or graveyard. Because of his unusual wording, you can discard Dragon Ice and special summon him. (The exact same card you discarded.)
Dragon Ice is fairly easy to summon and his WATER attribute with his level make him good with Sea Stealth Attack. In the situation you summon Dragon Ice to prevent an OTK, Sea Stealth Attack will protect your Dragon Ice, making it troublesome for your opponent to attack into it.
A very strong card if you can bring it out on the field, however people probably overestimate this card and most likely it will not be run in the most optimal Sea Stealth Attack decks (or maybe at most 1 copy). You’d run maybe one copy since it can be searched thanks to Legendary Fisherman II. This card can be special summoned from your hand OR graveyard by tributing 2 water monsters, so if you start your turn with one water monster already on the field, and you can normal summon another water monster, you can special summon it from your hand or graveyard that turn. When it’s special summoned you can set one Sea Stealth Attack from your deck (pay attention to special summon it and not normal summon it, and that Sea Stealth Attack cannot be activated that turn). Its last effect allows you to, once per turn, if your opponent activates a card or effect that targets one of your water monsters, you can negate it and destroy that card.
This level 5 monster can be normal summoned without a tribute when A legendary Ocean is on the field. It will have 2400 attack and will be immune to your opponent’s monster effects (this does not protect against Dakini’s effect!) as long as Umi is on the field. When this card leaves the field because of your opponent you can add a level 7 water monster from your deck to your hand. In the 3SD version you could search for Suijin, and in the last version you can search for Citadel Whale.
Because each of these decks run a lot of Water monsters, there will be times where you couldn’t possibly summon them all so with this card you can get use out of them. It also works great with Citadel Whale since Citadel Whale can be special summoned from the graveyard, so if you have Hammer Shark and special summon Abyss Soldier with Citadel Whale in the hand, you can freely use Abyss Soldier’s effect because it doesn’t matter if Citadel Whale is in the graveyard or hand if you plan on special summoning him that turn.
If you haven’t drawn A Legendary Ocean yet you can discard this card to bring it to your hand. If did draw it already it’s still a decent monster with 2100 attack while ALO is on the field. It can be special summoned with Hammer Shark while ALO is on the field, or can be discarded with the effect of Abyss Soldier if you don’t plan on summoning him.
The only reason you’d run the Three star demotion skill is for this card. With the recent changes made to certain skills you can now normal summon one of the Gate Guardian pieces (like Suijin) without any cost or requirement. This can only be done once per duel, so if you draw into another Suijin you can discard it with Abyss Soldier’s effect. This card will also be protected by Sea Stealth Attack since its original level is 7 and it is a water monster.
It also comes with its own little protection because once you can make a monster’s attack (that attacks this card) go to 0. So if you set this card turn 1 you can use it to stall, and cause a lot of damage to your opponent (because in most cases if they want to deal with it, it’ll have to be face-up).
When looking at strong level 5 monsters (which can be normal summoned without a tribute thanks to ALO), there aren’t that many great options. Two of the more interesting cards (to fill in those slots) are Mecha Sea Dragon Plesion and B.E.S. Crystal Core. With Mecha Sea Dragon Plesion you can tribute one water monster to destroy a face-up card your opponent controls. So you can use this effect to get some use out of your other water monsters when they become less useful like Warrior of Atlantis (you basically get some use out of them just like Abyss Soldier does) , but you can also chose to tribute Mecha Sea Dragon Plesion to activate its own effect.
Because Cosmic Cyclone banishes a card, you cannot protect against it
with Sea Stealth Attack’s effect.
If you have a board with Sea Stealth Attack, A legendary Ocean and
two monsters whose original level are 5 or higher, you probably won
the game because with the combination of both Sea Stealth Attack’s
effects there isn’t a lot your opponent can do to come back.
Although this deck is very strong, the problem with it will be its
consistency. That’s why you can run balance/restart to help with your
B.E.S. Crystal Core
|A good option if you are looking for more level 5 Water monsters.|
|This water monster can be special summoned with Hammer Shark’s effect without the need to have ALO on the field. This card will summon a token when it leaves the field (except when destroyed by battle). So when you tribute it with Enemy Controller or for Citadel Whale, you’ll get a token|
