Granmarg and Book Of Moon

If player A summons Granmarg The Rock Monarch and player B activates Book of Moon to flip Granmarg down does Granmarg destroy itself if it's the only face-down? I like 75% sure that it doesn't.

Why would they do that, when the summoner of Granmarg has to select a target first?

You're answering like John. Yes or no? I'll take that as a no, so I figure you won't have a target after Book Of Moon is chained right?

It would because the effect would activate, then the opponent would chain the effect of book of moon. Book of moon would resolve first flipping the monster face down. After the effect is over then Gramarg's effect would activate destroying himself.

It would be the same if you just summoned Zaborg and they had a monster on the field, then they activated Ring of Destruction as chain on their monster. Ring would activate then without a monster Zaborg destroys himself.

Actually no. First when you summon a monarch, assuming the summon is not negated, you have to declare your target after that your opponent has a chance to respond likewise you can respond to whatever they do. After that resolve the effect of the monarch on whatever the original target(s) declared upon activation. No matter what happens to the declared target(s) you do not change its effect to another card.

So in short Granmarg would not destroy itself.

<laffin> You're answering like John?

While a simple yes or no answer will tell you what happens, it's more important to give the mechanics of why or why not as ilikepiesodie has done. It goes along with the old wise phrase of ,"Teach a man to fish...."

When you understand the game mechanics you'll be able to answer your own questions 90% of the time. If you only know a single card ruling with a yes or no answer then when a similar card comes along you'll be asking the same question for it.

The game mechanic here is that trigger effects such as Grammarg target as activation, no cards target at resolution, the target is named as part OF activation, once a target is named the target can never change. So if the target disappears before resoulution the effect resolves without effect.

If the target card was book of moon and you chained book of moon to the effect, Granmarg's effect's target is gone, therefore nothing happens. He wont destroy himself because he was face up on activation and the face down book of moon was the target.
