When you play this card, it becomes a copy of the command card your opponent played on his last turn. Follow
"Follow the instructions on that card as though you were actually playing it, except reverse any section references made on the card"
1) as though you were actually playing it --> you can chose ANY section as you would do if playing that card from your hand.
2) the exception about reverse section is applied only if it's referenced on the card.
These are my 2 cents.
