, Discard an artifact card: Search your library for an artifact card with mana value 1 or less, reveal it, put it into your hand, then shuffle.

Choose a card type, then reveal the top four cards of your library. Put all cards of the chosen type revealed this way into your hand and the rest into your graveyard. (Artifact, creature, enchantment, instant, land, planeswalker, sorcery, and tribal are card types.)
