Grand prize: 4 of every card at release

So the winner of this tourney would actually get himself the same topup as PRIMAL or above tiers => "4 of every non-exclusive card in the game at release". Since what do they mean with exactly with non-exclusive? This limitation isn't even mentioned for the grand prize of this tourney!

Concidering the prize, I think this will be a one time tournament (possibly spread across different smaller tournaments) between pro players?

Do we have any more details on this?
