not all, but ludibria ventis, manta ray, heavy melee shrine, amuni ship, monumnt of ancient knowdlege, savory bites, tender tag team and unleashed unit upgrade are very good; plus training dojo, bumblebee stable, azure stable and desert watch tower can be usefull.
I have another opinion4 buildings of that season pass are good
Who think that is not much for 2500 diamonds, don't buy it
(I suppose that rewards change every season)
however, better buildings are always welcome
