Whenever a creature is dealt damage, its controller may exile that many cards from the top of their library. They may play those cards until the end of their next turn.
Players pay all costs and follow all normal timing rules for cards played from exile with Expedited Inheritance’s permission. For example, if one of the exiled cards is a land card, they may play it only during their main phase while the stack is empty.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
