Waking Nightmare is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.
Official card text
Target player discards two cards.
Complete guide
Waking Nightmare is a classic discard spell that forces your opponent to shrink their hand size at sorcery speed. As an Arcane spell, it carries additional synergy within the Kamigawa block, allowing for powerful splice interactions in specialized decks.
What It Does
For three mana, Waking Nightmare allows you to target any player and force them to discard exactly two cards from their hand. Because the text does not specify 'at random,' the target player chooses which two cards to discard.
How It Resolves
First, you cast Waking Nightmare and choose a target player. If the target is legal when the spell attempts to resolve, that player selects two cards from their hand and puts them into their graveyard. If the player has only one card, they discard that one; if they have no cards, the spell resolves but nothing happens.
Common Mistakes
Players often forget that this is a Sorcery, meaning it can only be cast during your main phase when the stack is empty. Additionally, remember that you cannot force a player to discard if they have protection from black or hexproof, as the spell requires a target.
When to Play It
Waking Nightmare is most effective in the early to mid-game to strip away your opponent's win conditions or reactive spells. It is particularly strong against control decks that rely on holding a large hand of answers.
Interaction examples
If your opponent casts Demonic Tutor to find a specific card, you can use Waking Nightmare on your following turn to force them to discard that card along with another, effectively neutralizing their search.
After you clear the board with Toxic Deluge to remove threats, you can cast Waking Nightmare to ensure your opponent cannot easily rebuild their board state from their remaining hand.
