Forum:Legendary Ocean

I want to know if A Legendary Ocean's effect of downgrading monsters' levels by 1 counts for cards that you draw (when they become a part of your hand) whether the effect stays with the cards it applied to after it goes to the graveyard and whether the effect accumulates per 'A legendary ocean' card. For example, if I go through 3 of them, and I have a level 7 monster in my hand, does it become a level 4 once the 3rd one is played?
