Hard to say, but...
I dont have the game yet, but I believe that you should go for Belial Edge > 6B and Deadspike > 6B when possible.
And before 5D's, try to add 2C (more untechable, therefore, mostly used for later combo parts) or 5C (more damage, less untechable).
Midscreen, 5B 6A Gauntlet Hades/TK GH links are the best and works on everyone.
