Forum:Stardust Dragon Help

If I have Stardust Dragon on the field and I use its effect to negate a card in my opponents turn, and he decides to play Monster Reborn on MY stardust dragon, does it come back to me in the end phase due to its effect?

Also if it doesnt come back to me, the official rulings state that if my opponent controls stardust dragon and he uses the effect, I get the stardust dragon back at the end phase, does this go for cards used on it like Monster Reborn or just cards like Brain control etc?

Thanks in advance
