Can I use Brightwater to return Darkstar to it's owners hand?
"after a card is discarded from a players hand, kneel BK to return that card to its owners hand"
I wasn't sure how the timing would work - Darkstar is a passive
If they were both responses, would the first response be successful and the second unsuccessful
I also assume I cannot use BK to return a card discarded from hand as a cost ~ because there is no window to do this?
