Artifact Recursion

Cards that loop artifacts back from the graveyard, whether to hand, to the battlefield, or by casting them directly. Includes Goblin Welder and Daretti, Scrap Savant swapping artifacts between yard and play, Emry, Lurker of the Loch casting artifacts from the graveyard, Trash for Treasure and Refurbish reanimating big artifacts, and death-trigger loopers like Myr Retriever and Scrap Trawler. Narrower subset of graveyard.recursion, scoped specifically to artifact-only returns; generic any-card recursion stays in the broader graveyard category. Distinct from artifacts.artifact_tutor, which pulls from library rather than graveyard.
