Previously, I believe Bitter Rivals was ruled that if your opponent did not have a key word in hand and you did not want to change the zone, you could just ask them to pitch a key word anyway. However, it was ruled differently during the SEC. Which one is correct?
Bitter Rivals
E Reveal your hand: Your opponent reveals their hand. Either change the attack zone of this attack to any other zone or your opponent discards one card with a key word ability (Their choice).
