Forum:MST, Continuous Trap Cards and more

So here are my questions

1. Can I set MST and activate it on my next turn targeting the same MST?

2. Let's say my opponent has 3 face-down cards in his/her spell and trap cards zone and I have a set Call of the Haunted( with a monster I can special summon in my grave). My question is can I play Heavy Storm and chain my Call of the Haunted to prevent my opponent from negating my Heavy Strom with a Dark Bribe or a Solemn Judgment?

3. Can I activate Royal Oppression at any time or do I have to wait for a special summon to activate it? Coraguardian 02:27, June 1, 2010 (UTC)
