Kindred Enchantment — Demon

Whenever one or more Demons you control attack a player, you draw a card and lose 1 life. At the beginning of your end step, create a 5/5 black Demon creature token with flying, then mill two cards. If two cards that share all their card types were milled this way, sacrifice this enchantment.
