Yeah I had problems with my base set too! I bought about 9 or 10 boxes normally 2 or 3 at a time and over that period only got 1 wanderlei and 1 velasquez so I see how people struggle to finish it, I sold a base set but I had to buy about 10 cards singley off eBay it's stupid you should be able to put 1 together after a couple of boxes!
I'm not too far off my blue autos, still need the top dogs which I'm saving till last tho ie lesnar, Gracie, gsp, a.silva..
Thinking about hocking off all my Matt relics except for my wanderleis and my cheick Kongo bloodlines auto so I can finish my insert sets and blue autos!
PM if there is some matts you need I have quite a few incl a Liddell 4/5 colour!
Ps I herd the guida relic is almost impossible to get!
