if u remove d.d. survivor and a light to bring out chaos sorcerer does d.d. survivor come back to the field?

does newdoria work if skill drain is on the field?

This belongs in the Rules of dueling.

It does belong to in the Rules of Dueling forum, but i think i can answer the questions.

1) Read D.D. Survivor, i think its effect states that if its removed from the field, then it comes back, but not if its removed from the graveyard.

2) No

I'm not sure on the Newdoria one, but i think that i'm right.
