Huh, this can sound nasty... I will throw lots of rocks (imagine the rocks as figurative unbalances this card may have) and I will enjoy seeing how you deal with them, both if you evade them or get hit in the head with them
1- I use this with fractal and Light Dragons (6xMartyr 6xFractal 6xLight Dragon, some pillars/towers/pends, Mark of Whatever, only a Duo). I play my upped Martyr, then fractal it, then... Well, I play all of them and after the first fractal, fractalling dragons gets more and more fun. Seem a bit too powerful, mainly with upped Martyr.
2- What happens if the top card in my hand is a targetting spell? Like Fire Bolt... Or if it's a Spark? I guess it dies instantly...
3- It's hard to see a non-casual use of the passive ability. I won't pack this card just to play a random card of my hand (one I may not even want to use) once my hand is clogged. I see it more like the active ability is too cool, and the passive is "meh".
Anyways, I like the picture, love the concept, and it gives me sooooo many decktype ideas, like MartyrNovaBows with 3/4 cost creatures instead of current 2/3 cost NovaBows, or... well, that's all I've imagined yet
I actually wouldn't complain if Zanz made this a new card in the game as it is now.
