If you sell event units on farm missions that you don't want/need you can get more. 150 RCs from a farm event should be easy if you aren't trying to max the unit.

Just slowly save them up with an extra gold here and there and maybe some farm plats and you will eventually get there, maybe even before getting a black.
Note that event units give WAY less RC for discharging than their Premium counterparts. Like a premium gold gives 20, an event gold would give IIRC 3, plats it's 100 and 5. You're better off using those farmed event units as mini-platinum armors. Purely free players will take ages to get the 1k for the DK currently there unless you get lucky enough to pull duplicates of plats and blacks that you aren't going to use (sell a duplicate Aisha/Nanaly/Minerva and your soul will burn in hell while your mind screams "WHY THE HELL DID I SELL THAT OP UNIT???)
