Betrayal of Flesh reads
Choose one — Destroy target creature; or return target creature card from your graveyard to the battlefield.
Entwine—Sacrifice three lands. (Choose both if you pay the entwine cost.)
If I cast it with entwine, can I target the same creature with the first half (while it is on the battlefield) and the second half (when it is in the graveyard)? Or do I pick the target for the second half before the first half resolves?
