So... If it was the other players' turn could i use the "may play the top card of your library if it's a land card".

Enabling 2 land drops for my "1" turn..
From the mtg rules:
305.3. A player can't play a land, for any reason, if it isn't his or her turn. Ignore any part of an effect that instructs a player to do so. Similarly, a player can't play a land, for any reason, if that player has used all of his or her land plays for that turn. Ignore any part of an effect that instructs a player to do so.
So no, you cannot.
Bummer and thank you
