Pontid+baltid if we go by phenotypes, which is a very Russian combo(southern russia/ukraine=pontid/alpine/north pontid, central russia/belarus/northwestern russia/baltic states=baltid/east nordid/neo-danubian)
Finnish people look either like Swedes or like Balts, although there are some very specifically finnish faces like, for example, Jammpi(you won't confuse him with a Swede or with a Lithuanian)
