Thanks for the report! Much easier to follow the game with the overview shots.
I also liked the comments and plans between the turns.

You seems to have a massive load of bad luck. Both with activating and in some engagements. (The Avatar for example

)
Thoughts:
Why didn't you attack the Vultures? My first target would have been them and it looks like they are out of the AA bubble or close to it... You targeted the already activated artillery in turn one instead?
In my games they rarely survive turn 1 as they hit hard, so my opponent fear them and die "easy"
It also puzzles my why you didn't use the SC reroll on the vampire in turn 2 or 3 and why you didn't go for the "unprotected" blitz in the end. (Going after a full Russ company in the last turn is doomed to fail

)
I also noticed that you used the SC reroll in turn 1 before the Wraithlord had entered the board and that the broken Waveserpent survived loosing an engagement even though not being fearless but that is minor things

I know it was not your choice but it is kind of stange that the inf co didn't move up some of its units in base to base with the Wraithguards when they assaulted. That way they would have had taken away their extra MW attack...
