Mastermind Plum (Borderless) [Ravnica: Clue Edition]

Mastermind Plum attacks, exile up to one target card from a graveyard. If an artifact card was exiled this way, create a Treasure token. (It's an artifact with "T, Sacrifice this artifact: Add one mana of any color.")

Whenever you cast a spell, if mana from a Treasure was spent to cast it, you draw a card and lose 1 life.
