Your deck seems a bit all over the place. You run a few of the goodstuff cards for lands like gitrog, tatyova, et al, but there doesn't seem to be much of a unifying theme. For example, if you had a scapeshift in there, I could see cards like ob noxious the fallen, er ob nixilis the fallen and the other landfall payoffs, but I am not seeing a ton of other good land matters cards that win you the game...they just generate value.
For golos ability, I don't know that I like the ability to play on my opponents turns. I mean, yes, you can activate and get some free stuff with the alchemists refuge, but most of your best stuff wants landfall triggers and exiling lands seems bad. Failing that, you don't have a lot of continously awesome tutor to the top of your library. Vampiric tutor, imperial seal, etc. Yeah, I get it, those are expensive, but worldly tutor, enlightened tutor, and mystical tutor aren't too bad and frankly, to the top of the library is precisely where you want it if you aim for his ability. Failing those, something that fits the bill would be liliana vess or bringer of the black dawn. Bringer especially is beautiful in a deck like this.
I guess what I am asking is, what is your unifying theme?
Edit: I stand corrected on the tutors. Everything but the mystical tutor could be seen as awfully darned pricey. My apologies on suggesting expensive cards, but it can help with what you might be trying to do.
