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 Headlong.
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.
Not according to my experience. I've seen people active this card during my draw phase but I'm never able to do so during someone else's draw phase. I always have to wait until they play a card, usually one that targets this, and I can't flip it AND activate the banish effect at the same time.
You need to turn Activation Confirmation to Toggle or Tap
it's stupid easy to just keep looping Azure-Eyes and Dragon Spirit together until you've worked through all 3 copies of this in your opponent's deck. I feel kinda guilty going up against SSA with my Blue-Eyes deck these days.
what is the counter for this ? does "Hey Trunade counts" when attacking since it brings back the cards to the owner leaving the field empty then attack with monsters? it's bit overpowered if it doesn't
