I run a bunch of non-conventional lands to make sure I always hit my colors when I need them, the damage from City is usually irrelevant, but would the first one for me to cut. I consistently go off turn 2-3, sometimes even 1 with SSG. I also like the land because it allows to me play Abrupt Decay and Dispel in the sideboard to deal with sided in hate.
One question is why the lone Jin-Gitaxias? Because, sometimes after looting once or twice, I will have two or even more Emrakuls and I hated discarding one and resetting my graveyard too early because I needed to keep what was in my hand. I decided to cut one Emrakul for him, and I think putting in Jin on an opponent's end step unanswered is a huge setback for them.
