Flying
Whenever Lord of the Void deals combat damage to a player, exile the top seven cards of that player’s library, then put a creature card from among them onto the battlefield under your control.
Lord of the Void’s ability isn’t optional. If there is a creature card among the seven cards you exiled, you must put one onto the battlefield under your control.
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.
