When this card is activated: You can activate 1 "Umi" from your hand or GY. While "Umi" is on the field, this face-up card gains these effects.
● Once per turn: You can banish 1 WATER monster you control until the End Phase; this turn, face-up Spells/Traps you control cannot be destroyed by your opponent's card effects (even if this card leaves the field).
● At the start of the Damage Step, if your WATER monster whose original Level is 5 or higher battles an opponent's monster: Destroy that opponent's monster.

  • Can place 1 “Umi” Field Spell from your Hand or Graveyard when this
    card is activated.
  • Once per turn you can banish any WATER monster you control until the
    End Phase, and all your face-up Spell or Trap cards cannot be destroyed
    by your opponent’s effects.
  • Enables WATER monster with original level 5 or higher to destroy
    opponent’s monster at the start of Damage step.


  • Relies on “Umi” Field Spell to activate.


  • If you have replaced Umi with A Legendary Ocean, do not activate this
    card’s effect of placing Umi from your Graveyard, it will return Umi to
    the Field and destroy A Legendary Ocean.
  • You can banish any WATER monster that has sustained negative effects
    from cards like Wall of Disruption, and return to the Field during the
    End Phase with its stats restored.
  • When your opponent activates Super Rush Headlong in response to your
    level 5 or higher WATER monster’s attack, Super Rush Headlong will take
    precedence over Sea Stealth Attack’s effect that allows level 5 or
    higher WATER monsters to destroy opponent’s monster at start of Damage
    step. However, you can choose to banish your attacking level 5 or
    higher WATER monster instead to avoid being destroyed by Super Rush
  • When your opponent uses Cosmic Cyclone to banish your Sea Stealth
    Attack (after you have banished a WATER monster), your banished WATER
    monster still returns to the Field at the End Phase.

Field Spell

You require these Field Spell to activate Sea Stealth Attack. A good combo is to use Warrior of Atlantis to search for A Legendary Ocean from your Deck.

Recommended Monsters

These WATER monsters with original level 5 or higher can destroy your opponent’s monsters at the start of Damage step.

Short answer: No.

Long answer: You cannot react to a monster's summon until that monster is already on the field. In this case your monsters would already be in the graveyard.

You could always set your toggle to 'on' and use SSA's effect to banish one of your monsters at the start of their turn.

What toggle?
Just ban this card and Amazoness onslaught in the meantime. Both are just stupidly broken. Same as the stupid Sylvan meta where you just sit and watch the other player burning his deck out.

Then tell us one SR/UR card from a box that is actually in the limited list right now.

Bet you can't, because there's none.

Besides, if they are willing to limit box SR/UR, we would already have Ties, SSA, Komushroomo, and Mask Change limited since a long time ago.
SSA with Wiz Fur Hire.
Man that's gonna be an annoying control deck.
this card and amazoness onslaught are out of control! every duel I have to encounter either one of the two or sylvians, with the latter actually being the mildest and slightly possible to beat
why tf did they have to release this card it basically makes its controller completely invincible! amazoness onslaught is almost as bad but at least that card can be destroyed with card effects, this card literally just makes spells, traps and monsters completely untouchable!!

I think Amazoness Onslaught is worse, since it banishes your monster. I could beat SSA by repeatedly summoning Arkbrave Dragon from the grave, but if Amazoness Onslaught touches my dragon... it is over for me. Btw, you can chain and destroy SSA before it resolves. You'd still need a quick-play/trap to chain plus one more card to bait your opponent into using SSA's banishing effect though.
Why everytime sylvan activate their effect in GY i cannot chain with this even toggle button is ON?????

You can build a casual fun ssa gishki deck. Use opponent monster to ritual summon and banish it to have it regain original attack. It's only meant for casual and fun play but not for high rank play

Where are those Sea Stealth decks, yo?
Oh yeah, someone mentioned destroying SSA/Umi/Legendary Ocean with chaining shenanigans. Basically, just bait your opponent into activating SSA's banishing effect, and chain a S/T destruction card to it. Since the last card in the chain goes first, you will be able to destroy SSA before it takes effect. So if you don't have Cosmic Cyclone or Anti-Magic Arrow... packing some S/T destruction quick-play spells might do too.

I’ll just make it stupid for me to understand.

Most people try to 🔥 the trap on sight? - thus ending in a fail.(they will banish and 🔥 is immune to destruction).

Your suggestion is,

Do a fake bait attack and when they vanish it, activate a QUICK PLAY destruction of trap 🔥.
Someone please tell me how you counter this card. It’s all over PVP and they should really limit this card to just 1. Anything you attack with gets destroyed

Bait Vanish.
Super Rush the other monster.

Problem is when the fuqq boy vanishes traps are immune from distruction.

You need like 2 monters,
Life points low enough to kill,
Super Rushes.
Destroy the trap first >
He will banish one monster >
Summon a monster..... >
your move
they need to limit this 🔥 to 1. way to OP.
