I am guessing that you mean the symbol?

If so it's colorless mana. Some cards in the "Oath of the Gatewatch" block (IIRC) specifically required colorless mana to play. There are no such cards in the current Arena card pool, so in arena it's just mana that you can use to pay generic mana costs with ( etc).
