Shadow stalk and Counterblast

[Shadowspite]

Currently, shadow stalk targets an enemy model within 10" of the model casting the animus, and then when the target moves, you get to make a full advance.

now, since shadow stalk is on the model targeted, not you, you can have counterblast on yourself (I believe)

now, if the model that is shadow stalked advances into your command range. which effect triggers first?

or do you get to choose?

Shadowstalk first (as per timing rules).

Shadowstalk first (as per timing rules).
Non-attack effects before attack effects got generalized to every situation? (If I remember correctly, it was only in the "after attack is resolved"-phase, only for the AP.)
