nothng happens
Yes if you complete a puzzle in one of the buidings you go underground you can find UNOWN and capture them and if you speak to one of the people aboveground they will give you an UNOWN Report to regisster the types of UNOWN in.
When you complete all the puzzles in the ruins of alph a guy will give you the unown report, when you catch all the unowns go to the house in the ruins of alph and give it to him, he will let you battle arceus LV.70.
People say it has something to do with celebi, saying you then (if you have National pokedex) can catch celebi with a GS ball (meaning go to the shrine and put the GS ball in the shrine in Ilex forest) Celebi will appear (as what people say) at lvl 30. if it is caught and first in your party, in ruins of alph instead of unowns its celebis This is a complete Lie. Nothing that I know of happens, because I havent, but talk to the guy who gave you the Unown report, maybe it'll do something.
they spell the alphabet and maybe you get a rare Pokemon
