^ Also a bad thing.
This is a direct counter to immorushes and speedbows? If this is the goal of this card, it fails miserably.
1st, if you are going to use it in your first turns (lets suppose, 3rd turn), you are also probably not dealing real damage to your opponent. All your quanta is drained (except Death), so you will also not be playing anything, while the opponent will be growing his creatures. You get no advantage.
2nd, immorushes and speedbows can easily pack a couple of explosions. Sorry, you lost.
Shards should be powerfull, but the all-or-nothing way of this card concept sucks.
