MAGIC: THE GATHERING
|Type:||Legendary Creature - Aetherborn Rogue|
When Gonti, Lord of Luxury enters the battlefield, look at the top four cards of target opponent's library, exile one of them face down, the put the rest on the bottom of that library in a random order. For as long as that card remains exiled, you may look at it, you may cast it, and you may spend mana as though it were mana of any type to cast it.
In addition to being a mainstay of Standard control decks, Gonti set an interesting precedent: an effect that exiled cards that you could cast even after Gonti was killed or exiled.
