I refer to this as my current Unholy Trinity. The OOO Driver is the easiest to obtain but the other two are probably going to require the donation of bodily fluids to obtain.
Right now my grails are SHF Deneb and SHF Gai for under ridiculous prices.
Missed out on two different opportunities to get Deneb for $50 a couple months ago, and I can't find him for anything less than double that right now. And the last Gai I saw on Mandarake was over 9000!
