Prophet of Inelis

At the beginning of your upkeep, obtain gold. Then obtain silver X times, where X is half the number of permanents you control named Gold rounded up. (To obtain gold, put a colorless artifact token named Gold onto the battlefield. It has "Sacrifice this artifact: Add one mana of any color to your mana pool." To obtain silver, put a colorless artifact token named Silver onto the battlefield. It has "Sacrifice this artifact: Add {1} to your mana pool.")
