Tomb Trawler 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

: Put target card from your graveyard on the bottom of your library.

Complete guide

Tomb Trawler is a versatile utility creature that ensures your most valuable resources are never truly lost to the graveyard. This artifact Golem provides a repeatable way to recycle cards, protecting your deck from being emptied and setting up future draws.

Recycling Your Graveyard

Tomb Trawler features a simple but effective activated ability: for two generic mana, you can move any target card from your graveyard to the bottom of your library. Because this is an activated ability and not a 'mana ability,' it uses the stack and can be responded to by opponents. There is no limit to how many times you can activate this in a single turn, provided you have the mana to pay the cost.

Resolution Step-by-Step

First, you announce the activation and pay the {2} mana cost. Second, you choose a target card in your graveyard; if that card is removed from the graveyard before the ability resolves (for example, by an effect that exiles it), the ability will fail to resolve. Finally, if the target is still legal, the card is placed directly on the bottom of your library. This does not count as drawing or discarding a card.

Strategic Timing and Common Mistakes

A common mistake is forgetting that Tomb Trawler can target any card type, including lands, creatures, and spells. It is best used in response to graveyard hate or to prevent yourself from losing the game if you have no cards left to draw. Remember that placing a card on the bottom of your library doesn't make it immediately accessible unless you have a way to shuffle your deck or search for it.

Interaction examples

Maintaining Momentum with Mana

Ornithopter of Paradise

If your Ornithopter of Paradise is destroyed and sent to the graveyard, you can tap other lands to pay {2} for Tomb Trawler's ability. By targeting the Ornithopter of Paradise, you move it to the bottom of your library, ensuring you can eventually draw it again or find it with a search effect to rebuild your mana base.

Reducing the Setup Cost

Foundry Inspector

With Foundry Inspector on the battlefield, the cost to cast Tomb Trawler is reduced from {2} to {1}. While Foundry Inspector does not reduce the cost of the activated ability itself, it allows you to deploy your graveyard protection much faster, leaving more mana open to actually use the recycling ability during the same turn.
