Forum:Call of the Haunted vs Light and Darkness Dragon

Hello,

Quick questions if I may,

1. It's my turn and I have a set trap on my side of the field (set the turn previous) and a face-up Rose, Warrior of Revenge. My opponent had a face up attack position Dandylion and Light and Darkness Dragon. I attack his face up Dandylion and when it goes to the graveyard its effect activates and is now negated, Can I chain to the negation and use my call of the haunted to return a card from my graveyard and than synchro summon?

2. If I Thunder King rai oh my opponents Mobius the frost monarch or battle fader, does the effect still go off? or is the summoning negated so there is no effect.

3. Also what is the speed of a monsters effect? i.e. d.d. crow. If I activate Call of the haunted can my opponent respond by playing d.d crow on my target thus destroying my call of the haunted?

4. Can I use stardusts ability during the battle phase? as long as it isn't during damage calculation?

Thank you in advance.
