Hi, we just want this confirmed.
Harrier Bees E: Reveal on copy of this card in your hand. Add the revealed card to your momentum, your oponent discards 2 cards Only playable if this attack is face up in your momentum.
To the question: He said that on the old forum, he read that you did not have to add the revealed card to your momentum, you could choose to just reveal, make your opponent discard and then put it back in your hand..
Well I think that the text on this card pretty much forces you to add the card to your momentum.
