The first is just to annoy an opponent by getting rid of their ship for 5 turns just before they're about to do something important.
Another use is for avoiding the Anti-time Anomaly. You can play this on yourself just before everyone dies.
You can also use this card to prevent a battle.
Or you can use it to avoid the borg ship.
If you want to be really mean, when the borg ship is headed toward your opponent's ship, use it on your opponent so when they get back they are on the borg ship causing instant death.
You can also use this card just if you don't want your opponent to move anywhere. The only thing bad about the card is that you have to pre-announce the arrival time. It would be fun to just appear suddenly and not having your opponent know about it in advance.
