Answer:
The subject of Al Qadhaa wa Al Qadr is THE only real "mystery"
in Islam. That is because it is a "mystery" to everyone. Pre-destiny vs Free-will.
Most things in our lives Allah has pre-determined. Example: when we are born, when we die, the time we live in, the culture we come from, the parents we come from, our genetics . . . need I continue?
But then , we are told, God had given us free-will. And yet again, we are told that God already knows what you - of your free-will will do; and so He has prepared the result - already.
That is and will always be a mystery to Mankind. That is because Allah is unfathomable. Just as Elohim is, to the Jews (it's the same God), Allah CANNOT be understood. We need to understand that.
And then again, we are told in a famous Hadith (saying) of Muhammad (peace be upon him): Laa Yarudd Al Qadr, Illa Ad-Duaa'. "Nothing turns pre-destination away, except prayers".
This complicates things more, it seems; however, the understanding of it is thus: Allah determines something will happen to His servant (you); but the servant is busy praying that it not happen (or whatever). So Allah removes that which He had written, and replaces it with something else He had written.
Allah already KNOWS that you would be making this prayer, so He set up another Qadr - to replace the one He had determined before.
NOW . . . WHY does God do all that gymnastics?
FOR A PURPOSE. If not for anything else, we know that Allah shows His servants what COULD have been in their lives had they been dfferent. Had the evil been good, He will show them what He had determined for them (because they really were free to choose). Had the good been evil (and not made those prayers) then Allah can show them what their lives would have been like, as well.
Glory be to God - who said that He would show us the truth of all that we did - on the Day of Judgment.
Yes, the effect only works after the effect resolves, so you can activate it in a chain to "Royal Decree". Cards like "Dust Tornado" can even destroy "Royal Decree" as it is chained to "Royal Decree"'s activation. When the chain resolves, "Dust Tornado" will destroy "Royal Decree" and "Royal Decree"'s effect will disappear since it is no longer on the field.
You can still activate them, but Royal Decree negates all other traps except itself, so they will be negated. You can however activate such a card like Seven Tools of The Bandit to negate the activation of Royal Decree itself and destroy it, because Royal Decree does not apply the negation effect until it resolves.
