OK questions about two plays that came up recently. I'll try to describe as simply as I can.

1. I have a legendary creature on the table.
2. Opponent targets that creature with Swords to Plowshares.
3. I respond by returning him to my hand with Karakas.

Where does the creature end up?



Next situation:

1. Opponent has two Narcomoeba on the battlefield. He also has two Bridge From Below in his graveyard. So if I kill the Narcomebas, normally four zombie tokens would come into play.
2. So I cast Drown in Sorrow which gives all creatures -2/-2 until end of turn. I believe that means that not only the Narcomebas are killed, but any zombie tokens that reappear afterwards, correct?
