"Destroy 3 of your mana crystals. Give all minions in your deck and in your hand +2+2"
I've been recently trying to make this card work in some kind of aggro deck. The biggest problem was that I always fell really far behind after playing this on turn 3. You rely on topdecking a buffed 1 drop to at least stay kind of on board after playing [card]Surrender to Madness on turn 3.
So why not also buff minions in your hand so that you do not rely on topdecking a 1 drop. Maybe you can play Whispers of EVIL and Surrender to Madness on turn 3 to be able to play a 3/3 Lackey the next turn.
3 mana value cards that don't actually add to your card value are always kind of dicey. This'd help a little bit, but honestly I just think it's way too expensive for what it does. I'd be down for them changing it to a 2 cost card that destroys 2 of your mana crystals and making it +1/+3 instead or something.
But I doubt they would make a balance change that extensive.
