Cogwork ArchivistHow it works & interactions with other cards

A Towering Defender

Standing tall with the Reach keyword, Cogwork Archivist can block creatures with Flying even though it doesn't have Flying itself. This makes it an excellent deterrent against aerial assaults while it sits on the battlefield waiting to use its activated ability.

Resolving the Ability

To use its ability, you must pay two generic mana and tap the Archivist. You then choose a single target card from any graveyard. Upon resolution, that card is moved from the graveyard to the bottom of its owner's library. Because the ability targets, the card must be in the graveyard when the ability is activated and when it tries to resolve.

Strategic Considerations

Common mistakes include forgetting that this ability can target your own cards or your opponent's cards. You can use it to prevent an opponent from reanimating a threat, or to put a powerful spell from your own graveyard back into your deck to be drawn again later. Note that if the card leaves the graveyard before the ability resolves, the ability will fail to do anything.

When to Activate

Since the ability requires tapping, you must choose between blocking or using the library-tuck effect. In many cases, it is best to wait until the end of your opponent's turn to activate it, ensuring you have a blocker available during their combat phase.

Interaction examples

Recycling Your Assets

Meteor Golem

If your Meteor Golem was destroyed earlier in the game, you can activate Cogwork Archivist's ability targeting Meteor Golem in your graveyard. By paying two mana and tapping the Archivist, the Golem is moved to the bottom of your library, allowing you to search for it or draw it again later to destroy another nonland permanent.

Protecting Your Library Size

Psychosis Crawler

If you have Psychosis Crawler on the battlefield and you are worried about running out of cards in your library, you can use Cogwork Archivist to put discarded cards back into your deck. This ensures you have more cards to draw, which in turn triggers the Crawler's ability to make opponents lose life.
