The problem with the initial card is you have to stop discarding cards once you draw Blood Queen(if that's the right play). But with this card, you can stop discarding cards but still play it as a 4/6, maybe at 6 mana and not as a 5 mana 2/6 that the Original card would be. Also, this has Stealth so, it's likely to connect once.
I know the time is far too early to say so, and the cards to see are still plenty.
But as far as we know, this card seems bad.
How would you buff her just a little? Not meant to make a broken card, just something fine to play with the known card.
Enjoy creating your slightly better version!
