{1}, Sacrifice Dross Skullbomb: Draw a card.
{2}{B}, Sacrifice Dross Skullbomb: Return target creature card from your graveyard to your hand. Draw a card. Activate only as a sorcery.
If the target of Dross Skullbomb's last ability isn't a legal target as the ability tries to resolve (probably because it has left the graveyard), you won't draw a card.
