Turning rares from T50 into relics is an interesting idea, but the problem with T50 is that it is horribly inaccurate at reflecting the 50 best decks. Even if there are fewer farms in the T50, the T50 decks will be the decks from the top 50 grinders, and usually not the decks from the 50 best players. T50 should go, especially once there is T500.
