Some of the Star Ships have flip effects that state you may discard cards to lower the stats of the revealed star ship. In borg mode can I discard cards from my hand to help another player diplomacy that ship or are the cards I discard only apply to my chances of getting that ship?

Also am I only the one that thinks the new borg ships effects are useless. I have to discard 4 cards to let another player trash a card. That is way to much and not worth it. As for the other 3..... I just don't know.
