Feedback issue: #5529
Aura replacement code tried to remove the second face from the original zone which had ownerId == null. Now, we remember the first face (the original card) and remove it from the old zone before creating a permanent out of the second face.
* Accursed Witch's death trigger now requires targetting opponent instead of using aura replacement effects

Previously you could attach Infectious Curse to either player and get around hexproof
The ability text has also been updated to match the Oracle text of Accursed Witch.
