How does SSA protect Legendary Ocean? A field spell card. Both of its effects help WATER Monsters but I see nothing in the text about spell/trap cards.
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).
It's a trap card. It doesn't need to say it can be used in either player's turn. That's like saying Rush Recklessly or Jar of Greed should specify that. You could try using it if, for some reason, you can't grasp that. ;p
