Campaing - 8 mission (HARD). I did it with STRATEGY! (Check Description) [Guilty Gear 2 -Overture-]

I lost 20-30 times before that. But finally get it, how to beat it without rush. The plan:
1. You need to research "Blockhead" first, then researh "Blade";
2. Destroy first enemy group from Valentines Masterghost;
3. Go help Dr. Paradigm, meanwhile hire Blockhead and Blade and set them in "lower" line together;
4. You need to research "Pencil Guy" and hold off the fisrt reinforcements by yourself mostly, or with Dr Paradigm (as you like);
5. Hire "Drill" and "Pencil Guy" to hold "top" line from second reinforcements and also hire "Pencil Guy" for lower line as fast as possible ("Pencil guy" is your second necassary key for victory!);
6. Run back and there, to defend different places, if necessary;
7. Be ready to defend Dr. Paradigm from 3rd reinforcements and 4th reinforcements (As you can see, my aslmost died from it, even if I'm there)
8. By last, research "Engulfer" and "Fire Wheel" for ending this all, and try not forget search for treasure chests with "Mana" at Ghosts.
9. You see me in video from "7" part of my plan, when I deal with 4th reinforcements;
10. Use all your items from chests. If you do not need them - sell them!;
11. ......
12. Profit!

I do not wanted to just "rush" this most Hardest mission (actually, it's not so easy). So I found a way to win, using servants right.
