Both victory conditions are very faith heavy, Russia get the Lavra which allow Russia to build a better version of the holy site in every city at half price no district slot needed. Lavra also give extra great prophet points and extra great artist points, both are very nice for religion/culture victory. Russia can very well get the first pathernon and if it pick the thundra pathernon it can very well generate loads of faith just from adjacency bonus. Not only is faith needed for all religious agent but also for national parks which is very important for culture victory. Russia also have a rather nice starting bonus in that it get alot of free tiles.
