Geralf's Mindcrusher 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
When this creature enters, target player mills five cards. Undying (When this creature dies, if it had no +1/+1 counters on it, return it to the battlefield under its owner's control with a +1/+1 counter on it.)
Complete guide
Geralf's Mindcrusher is a formidable blue Zombie Horror that exerts immense pressure on your opponent's library while proving difficult to keep off the battlefield. By combining a potent mill effect with the resilience of the Undying mechanic, this creature ensures that your opponent's resources are constantly being eroded.
Dual-Phase Disruption
Geralf's Mindcrusher features a triggered ability that occurs whenever it enters the battlefield, requiring a target player to mill five cards. Because of its Undying keyword, this ability will typically trigger twice: once when it is first cast and enters the battlefield, and a second time when it dies without a +1/+1 counter and returns from the graveyard.
Understanding Undying
Undying is a triggered ability that checks the creature's state at the moment it is put into the graveyard from the battlefield. If Geralf's Mindcrusher dies and had no +1/+1 counters on it, the ability triggers and returns the card to the battlefield under its owner's control. Crucially, it returns with a +1/+1 counter, making it a 5/5 threat that will not trigger Undying again unless that counter is somehow removed.
Strategic Implementation
To maximize this card, look for ways to reset its Undying status or utilize its high mana value. While it lacks immediate protection, the fact that your opponent must kill it twice to truly get rid of it makes it an excellent choice for control decks looking to stabilize the board and win via deck depletion.
Interaction examples
If you have Hullbreaker Horror on the battlefield, you can cast Geralf's Mindcrusher to trigger the Horror's ability. If Geralf's Mindcrusher has already returned via Undying and has a +1/+1 counter, you can use a later spell and Hullbreaker Horror to return the Mindcrusher to your hand. Re-casting it will trigger the mill effect again and reset it to a state where Undying can trigger once more.
In a deck featuring Psychosis Crawler, your strategy often involves drawing cards to drain life. Geralf's Mindcrusher complements this by attacking the opponent's other primary resource: their library. While the Crawler punishes them for the cards you hold, the Mindcrusher punishes them for the cards they haven't even played yet.
