P.S. I ran some simulation and, alas, even with 3 levels of upgrades in all Guild Store items, so extra 150% color bonus and extra 15% HP/attack, my Fairy deck wouldn't be able to farm Cursed City more profitable than it could now Castle 27. Unlocking CC 27 for raid would be possible, even with 2 levels of upgrades. There could be in theory some other deck + artifact set better suited for a particular CC location, but I haven't found it yet.
