For SS, Asuet -> Arthropleurid is good. I think you should put a Scylla 3rd and then a 2LP like Lap in the 4th slot. It's always good to start rushes with three 1LP souls.
For the file, I really think you need to focus on the level 3 units and shades and cut out the expensive grims and Dalos. So if you take out the 2 Dalos and Word of Dalos and also Split second decision, and maybe soul bind, thats 4-5 extra slots. When you get your 3 LeBeau DEF add him.
Some other things to consider:
- You could try using souls that are inconsistent, but when landed can basically win you the game. Miandela is a great soul for the 2nd spot, that will be totally useless sometimes, but if you can return a level 4 unit like BKR for free odds are you'll totally win the game actually. Another idea would be to put an assassin 3rd of 4th. A well timed assassin can also get you huge advantages when you land it. If you go the assassin route, something like consuming grudge might be useful.
- I see you got 3 MD fencer, I would highly highly recommend using him over MD melee. Fencer is an awesome unit do not underestimate this guy!
So just some thoughts. I hope I gave you things to think about I think you have enough cards here especially with Dalos to bump up to at least 40% win rate. If you just do a generic... shade - rev - shade - lebeau - md fencer -> etc I think you will be okay!
