Mind Raker 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
Devoid (This card has no color.) When this creature enters, you may put a card an opponent owns from exile into that player's graveyard. If you do, each opponent discards a card.
Complete guide
Hailing from the Battle for Zendikar block, Mind Raker is a sinister Eldrazi Processor that manipulates the very fabric of the exile zone. This colorless creature serves as a bridge between exiling your opponent's resources and forcing them to lose even more options from their hand.
Colorless Complexity
Mind Raker features the Devoid keyword, meaning it has no color despite requiring black mana to cast. This applies in every zone—hand, library, battlefield, and graveyard. Even if an effect causes Mind Raker to lose its abilities, it remains colorless because color-setting effects are applied in an earlier layer of the game rules than ability-removing effects.
Processing the Exile Zone
When Mind Raker enters the battlefield, its triggered ability gives you the option to 'process' a card. You choose one card an opponent owns in the exile zone and move it to their graveyard. If the card was exiled face-down, you cannot look at it; instead, you must select a group of face-down cards and choose one at random to process. The discard effect only happens if you successfully move a card from exile to the graveyard.
Strategic Discard
Unlike many targeted discard spells, Mind Raker affects 'each opponent.' In a multiplayer game, you only need to process one single card from one opponent's exile to force every opponent at the table to discard a card. This makes it an efficient tool for disruptive play in Commander or other group formats.
Interaction examples
You cast Mind Raker while your opponent has a card currently in exile (perhaps from a previous Delve or Exiled effect). When Mind Raker enters, you choose to move that card to their graveyard. Because you performed this action, the opponent must then choose and discard a card from their hand.
If you control Roaming Throne with 'Eldrazi' chosen as the type, Mind Raker's ability triggers twice when it enters. To get the discard effect both times, you must have at least two cards owned by opponents in exile to process. You process one card for the first trigger to force a discard, then process a second card for the second trigger to force another discard.
If an opponent exiles your Solemn Simulacrum (using a spell like Path to Exile), you cannot use Mind Raker to put it into your graveyard because Mind Raker specifically requires a card an 'opponent owns.' You must wait until your opponent has a card of their own in exile to trigger the discard effect.

How it works : Mind Raker
Original English text — Wizards of the Coast / Scryfall
- #1· Wizards of the Coast
Cards with devoid use frames that are variations of the transparent frame traditionally used for Eldrazi. The top part of the card features some color over a background based on the texture of the hedrons that once imprisoned the Eldrazi. This coloration is intended to aid deckbuilding and game play.
No other card is named in this ruling.
- #2· Wizards of the Coast
A card with devoid is just colorless. It’s not colorless and the colors of mana in its mana cost.
No other card is named in this ruling.
- #3· Wizards of the Coast
Other cards and abilities can give a card with devoid color. If that happens, it’s just the new color, not that color and colorless.
No other card is named in this ruling.
- #4· Wizards of the Coast
Devoid works in all zones, not just on the battlefield.
No other card is named in this ruling.
- #5· Wizards of the Coast
If a card loses devoid, it will still be colorless. This is because effects that change an object’s color (like the one created by devoid) are considered before the object loses devoid.
No other card is named in this ruling.
- #6· Wizards of the Coast
If a spell or ability requires that you put more than one exiled card into the graveyard, you may choose cards owned by different opponents. Each card chosen will be put into its owner’s graveyard.
No other card is named in this ruling.
- #7· Wizards of the Coast
If a replacement effect will cause cards that would be put into a graveyard from anywhere to be exiled instead (such as the one created by Anafenza, the Foremost), you can still put an exiled card into its opponent’s graveyard. The card becomes a new object and remains in exile. In this situation, you can’t use a single exiled card if required to put more than one exiled card into the graveyard. Conversely, you could use the same card in this situation if two separate spells or abilities each required you to put a single exiled card into its owner’s graveyard.
No other card is named in this ruling.
- #8· Wizards of the Coast
You can’t look at face-down cards in exile unless an effect allows you to.
No other card is named in this ruling.
- #9· Wizards of the Coast
Face-down cards in exile are grouped using two criteria: what caused them to be exiled face down and when they were exiled face down. If you want to put a face-down card in exile into its owner’s graveyard, you must first choose one of these groups and then choose a card from within that group at random. For example, say an artifact causes your opponent to exile their hand of three cards face down. Then on a later turn, that artifact causes your opponent to exile another two cards face down. If you use Wasteland Strangler to put one of those cards into their graveyard, you would pick the first or second pile and put a card chosen at random from that pile into the graveyard.
No other card is named in this ruling.
