The ability "Conspire" found on some instants/sorceries, reads
As you cast this spell, you may tap two untapped creatures you control that share a color with it. When you do, copy it and you may choose new targets for the copy.
What is the order of spells being placed on the stack when a spell is conspired? Normally, when copying a spell, it's when it is already on the stack, with cards like Twincast. However, looking at the text of Conspire, it seems to indicate that you copy the spell as it is being cast, which insinuates that it is not yet on the stack. Am I correct in this? To specify a situation in which this may be relevant, if I have Wort, the Raidmother out, and I cast Reverberate, and choose to conspire it, can the copy target the original? In what order are targets chosen? Is the original Reverberate on the stack yet?
