Teleport question

[Dimaz]

If you cast GR on both A and B you will catch both scouts in original provinces and they won't move at all. You should always attack with a scout from the province where you don't cast anything appearing in magic phase, that's the main rule. However you can sneak scout from A to B and attack from B to A, this way you'll have both scouts in place for the next turn.

I can confirm the following...

I had a scout in A and a scout in B.
Cast GR on A & B.
Sent A to B (not stealth).
Sent B to A (not stealth).

The result:
scout fights B.
GhostRiders fight B.
scout fights A.
GhostRiders fight A.

Having the scout in A attack A & scout in B attack B leads to the same result.
