As far as I have been able to confirm within the game itself, type advantage only works for 1 and 5 total cards. Therefore, anwhere from leader alone to leader +3 cards with type advantage gives a 15% boost. It is only when you have leader +4 cards with type advantage (ie all 5 cards) that you get the 20% boost. I have (unfortunately) confirmed this several times in the tower events and in PvP battles.
