Lack:
rare
7/7/7
quick
Each player loses resources equal to a cost of rares in his hand.

so you lose another 7/7/7 resources because you have Lack in hand.
Could be useful in a plague deck but it seems anyway a dead draw.
Maybe it should do something also if there aren't rares in opponent's hand.

made stock to be partly readded

I know it sucks compared to tornado, but if the enemy has some nice rares like bahamut, devil, residence of the gods etc effect if quite good

also - it's quick :)
