As Zero said, max affection is +5% atk and defense. It does not have an effect on stat carry over for evolution/amlgamation. For evolution, the highest affection level and the highest skill level between the 2 cards carry over. It doesn't carry over for amalgamate as amalgamate creates a whole new card. It also doesn't carry over for evolution accidents.
