ACTION: The next 2 damage dealt to one target unit are redirected to another target unit.
Can I play this in the action window after combat damage has been assigned? I know for indirect damage there is no window between assign and apply so I would have to play this "in response" to, say, Flames of Tzeenth. I'm curious if I can wait to see which of my units is being assigned damage in combat and THEN play this. What does "dealt" mean in game mechanic terms?
