I used to use this approach a few months ago, but then I realized it wasn't all that efficient. Leveling an HN to 40 is exactly the same as leveling an R to 40, and you get less EXP from HNs. So now I just cycle in one R/HR card at a time into a FAW deck and also use that on AWs:


 * First, I level slimes and metal slimes.
 * If I run out of slimes, I level skill unleash Rs (Furinkazan, Romance, Seagull).
 * If I run out of skill unleash Rs, I level experience bonus Rs (Detective, Io, Star Reader).
 * If I run out of experience bonus Rs, I level up passive bonus and treasure bonus 1-star HRs (Blacksmith, Cassandra, Druid, Oiran, Rotte).
 * If I run out of HRs, I level passive bonus and treasure bonus Rs that would be wasteful to evolve to HR (Canopus, Dogsled Girl, Kama).
 * If I run out of Rs, I level slime queens.

If I run out of stuff to level, I switch my event HRs into my FAW deck for friendship (they interfere with FAW fights, but I will hit level 50 long before 30 friendship). I also have a stockpile of HR Androids which I can max out with slimes or Rs in case I wind up needing more max leveled HSRs (has not happened ye, but maybe one day I will have really bad R card luck during an event).
