How does one win a debate...

1) I'm sure you're correct on the ordering being quasi-random; however, whether a given enemy mage casts his spell before a given mage of yours is random, as far as I know. (As it's dependent only on which ordering is used.) Which is really the necessary amount of detail for a summary of this nature, don't you think?

3-4) Come to think of it, you're totally right, the magically teleported units attack with the sneakers. I wonder what I was thinking... It's possible, however, I think, for a sneaking force to arrive at the province after the indie summons have done their work. Although now I'm in doubt: it's entirely possible that the instances I've observed were of the scout moving from a friendly province to a hostile province, not like I've paid that much attention to it before. If that were the case the structure would be certainly much more coherent. This could be tested by some industrious youth out there.

If your scout is hiding in an enemy province and then attacks another enemy province, it will attack as if it was hiding in the target province, I believe. If the scout is in a friendly province, it will attack as normal. At least works this way in relation to the magical summons; I wouldn't know for sure whether they will fight with the teleporters or the regularly moving units, though, as I never observed a situation like that.

This is too complex for a dummy like me, anyway!
