Any deck that wants card draw and happens to be running enchantments would be very happy to run this- control decks with enchantment-based removal, for instance
If your opponent discards a card while you control Leyline of the Void, abilities that check whether a card is discarded (such as Hollow One, or a madness ability of the discarded card) still work, even though that card never reaches that player's graveyard
Case in point: The 2018 North America International Championships, an hour-long card game complete with real-time statistics and commentators announcing the moves of each player, has been watched by more than 200,000 people
