Diraag, Void Summoner

Diraag costs {1} less for each card in exile.
Whenever an opponent draws a card, they instead draw 3 cards and exiles one of them
at random.
You may cast spells from exile that you don’t
own for {1} less, using mana of any color.
"Time and space do not bind me, as my reach
goes beyond that which no longer exists."
