Barclay APR reduction and SP CLI :)

So I got the guts to call Barclay after my 7th statement to request for APR reduction of my Arrival WMC and was successful from 24.24% to 20.24%. After giving me the APR reduction I asked for a SP CLI... Approved $700. Not a lot but better than nothing. So I got both APR reduction and a $700 SP CLI this pm. Image may be NSFW.
Clik here to view. .... Im thinking about adding 1 more Barclay card, what's the easiest card to get approved? Brand cards? My TU FICO 8 is at 693 right now with 7 Inqs.
