Tablet of Discovery (SOS)

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.

Niche mana rock for spellslinger decks, but the mill effect is unreliable and the mana production doesn't justify the slot over more efficient ramp options. Better as a budget alternative in casual red decks that can leverage the incidental card advantage.
