Beeswax, Forger of Gold

When Beeswax, Forger of Gold enters the battlefield, create a colorless artifact named Gold with "Sacrifice this artifact: Add one mana of any color to your mana pool."
Beeswax's power and toughness are each equal to the amount of Gold tokens in play.
Whenever a Gold token is sacrificed for mana, you may discard a card. If you do, draw a card.
