Here is the setup:
We play a team game, I play Legion, my friend plays Skorne.
The Basilisk Drake casts "Lurker" on the Seraph. The Seraph activates, shoots, casts Slipstream and walks away, also bouncing another model.
Does it work?
Why I'm even asking: Seraph has bushwhack, Seraph shoots, now Seraph should get to move, as a result of having bushwhack, but if I cast Slipstream, does Lurker expire, denying me the movement?
