Infernal Genesis
Enchantment
At the beginning of each player's upkeep, that player mills a card. Then they create X 1/1 black Minion creature tokens, where X is the milled card's mana value.

If the card has no mana cost (for instance, if it's a land), then its mana value is 0. This means no tokens will be created.
