I got 1 missing rare science-collectible via that and many uncommons and rares sciences+relics I already had.
So far I've got many rares and uncommons (sciences and relics) multiple times (record on rare 1 science is 3 or 4 and on rare 1 relic is same) w/o help of God Powers (most relics I got on 1st 3 days and after I got access to lab sciences also affter 3 days).
I suggest ability to buy missing relics for certain price, like 250000/500000 tech points for uncommon science/relkic-collectible and 1000000/1500000 for rare science/relic-collectible, that way it would be usefull to keep scientists after has gained all techs and got tech trophy since after has got tech trophy and villagers become armers with few doctors and maybe few builders (if there's something to do for them like was at VV4).
I don't think I have got any collection filled on VV-games so far, always 1-3 collectibles short of getting filled.
