Helios, Solar God

Flying
When Helios enters the battlefield, each player may choose to pay 5 life. If they do, they draw three cards. When Helios deals combat damage to a player, that player must discard two cards at random.
During your upkeep, you may discard a card. If you don't, Helios, Solar God becomes colorless and 0/1 until your next upkeep.
