$0.02 @ TCGplayer
Draw three cards. Target player mills three cards.
Follow the instructions in the order listed on the card: if you target yourself, you'll draw three cards, then put the top three cards of your library into your graveyard.
If the target player is an illegal target when Thassa's Bounty tries to resolve, it won't resolve and none of its effects will happen. You won't draw three cards.
