Tablet of Discovery

Artifact

When this artifact enters, mill a card. You may play that card this turn. (To mill a card, put the top card of your library into your graveyard.) {T}: Add {R}. {T}: Add {R}{R}. Spend this mana only to cast instant and sorcery spells.

Leaving no stone unturned is just the beginning.
