If you would draw a card, return a card from your graveyard to your hand instead. If you can’t, you lose the game.
If a card would be put into your graveyard from anywhere, exile that card instead.
The “if you can’t” in the first ability refers to putting the card in your hand, as well as being unable to choose a card. Thus, if you can’t choose a card during resolution, you lose the game.
