I know this has been asked at some point in the past, but searching through the new forums is unbearable so I wanted to ask again since I can't recall exactly.
I have a bitter rivals in play, I use the enhance, look at my opponent hand and he has a card with "Remy Multiple "1 or "R.Mika Reversal" for examples. IF he is actually playing as Remy or R.mika I know I can call keyword and force him to discard one, my question is if he is not playing as the named char, is the keyword dead for the Sake of Bitter Rivals Discard?

E Reveal your hand: Your opponent reveals their hand. Either change the attack zone of this attack to any other zone or your opponent discard 1 card with a keyword ability (your choice).
