Hrmmm, suddenly got and idea from this card idea.
How about making a permanent one? It would be nice to get quanta when your are forced to discard cards, so we now could counter Nightmare by a bit, since discarding means getting more quanta, making Nightmare less OP (it's not OP in any way, but..), even though it's kinda situational. But if you're gonna make permanent one, remember to make it un-stackable, or it will be OP if you draw too much with drawing cards and you got quanta to play the same card the next turn just because you discarded a card.
I just meh from the real card tho, targeting our own hand just meh to me. Permanent one would be easier to handle by player too IMO. 
But nice idea, never thought something like thisMeh, the 3rd edit
EditEdit: Woops, my bad. I guess I screwed my brain if I left it over midnight
But still, targeting hand is not fun, how about making it passive? You gain the quanta when you discard a card at your turn's end?
