IMO, Interviewer's Questions can be a very very good energy grabber. It just depends on the deck you're running. It was almost perfectly suited for my Tyranitar deck, which had 7 special energy and 6 basic. I'm not going to get more than half of my energy by using Cyrus, so I popped in 2 IQ. I didn't necessarily need them, but when I used them I was often rewarded. There have been numerous times where I've grabbed at least a Special Dark, a DCE, and a basic dark. It really depends on your deck.
