I channeled Shinji there for a second. Actually, it's the first time a card addressed the rivals, I believe (but I might be wrong), so it's a treat in a way.
3 cards, and what if the 3 are losers? The odds may not be that favorable, plus the opponent would, at least, get a preview of coming attractions. Then again, you'd get three cards and if all 5 are good, the pain isn't so bad.
More cards, the better, right? 6.9/10.
